3 1 Introduction While you can configure NetApp storage with the onboard OnCommand System Manager software, management of large numbers of storage objects becomes tedious without help from OnCommand Unified Manager (OCUM). Unified Manager allows you to grow your storage environment whether it is on-premises, in the cloud, or both, without growing your administrative staff by monitoring, alerting, and managing multple storage clusters at scale. The goal of this lab is to familiarize you with the basic operation and benefits of OnCommand Unified Manager. The activities in this lab explore how to manage availability, capacity, and protection over multiple storage clusters using OnCommand Unified Manager (OCUM). Specific use cases highlight different ways to access and use the information provided in the OCUM dashboard. Workflow Automation, OnCommand Insight, and OnCommand System Manager are covered in detail in other labs. A block diagram is provided of a OCUM environment. 1.1 Lab Objectives This lab demonstrates basic monitoring and management operations and identifies NetApp best practices where applicable. When you complete this lab you should have a basic understanding of the following Unified Manager features: Enterprise view of multiple storage systems and objects facilitating proactive storage management. Annotation and grouping features categorize resources according to criticality, application, location, and ensure consistent configuration and management of storage objects. Monitoring of resource availability and data protection relationships and alerting on issues before they become critical. Performance collection and analysis of storage resources. Wide variety of included reports. 1.2 Prerequisites In order to use this lab successfully, the following are the recommended prerequisites: 3 This lab assumes some prior experience with NetApp products.

4 2 Lab Environment This lab environment has been configured with a storage layout typical of a multi-datacenter company. While the two NetApp storage clusters below reside on the same layer 2 network, the storage within each cluster is configured as if it were at different geographical locations. There is a Windows 2012 R2 management station called the Jumphost that you will run the lab activities from. Notice that the environment includes this management station, the OnCommand services, and two NetApp clustered Data ONTAP nodes operating as two single-node clusters. This lab does not require application and database servers, so they are not included the configuration.

In order to demonstrate the capabilities of OCUM, you need many objects to monitor and manage. Having an understanding of the geographical location, business units, and applications for this hypothetical company environment is crucial to understanding why the Annotations and Groups features of the product are used in the examples that follow. The Finance and Sales business units operate out of Los Angeles, CA, while the Support, Engineering, and a second sales office operate out of New York, NY. The main applications for the company are Oracle, Exchange, vsphere virtualization, and basic file shares. Note: This lab environment does not include the application servers. Instead, it focuses on the data layout for a company that needs to support those applications. 5

7 3 Lab Limitations This lab has the following limitations: 7 All of the servers and storage controllers presented in this lab are virtual devices. Consequently, any operations involving movement of large quantities of data will not exhibit performance representative of real systems. Due to the inability to provide active load or historical performance data, the performance monitoring and analysis capability will not be covered in this lab.

8 4 Lab Activities This lab has the following activities for you to perform: Interface Overview on page 8 Interface Exercise on page 8 Data Protection Relationships Overview on page 14 Data Protection Relationships Exercise on page 15 Annotations and Groups Overview on page 19 Annotations Exercise on page 20 Favorites Page Overview on page 32 Favorites Page Exercise on page 33 Capacity and Utilization Overview on page 36 Capacity and Utilization Exercise on page 36 Alerts Overview on page 41 Alerts Exercise on page 42 Reporting Overview on page 48 Reporting Exercise on page Interface Overview OnCommand Unified Manager (OCUM) provides a consolidated view of your storage resources over a number of different storage clusters and sites. OCUM not only collects availability statistics, but it also collects and analyzes capacity statistics that alert you on capacity trends that need attention. Data protection relationships are monitored for compliance with replication lag time thresholds. Through the integration with OnCommand Workflow Automation, protection relationships can be created and repaired independantly of OnCommand System Manager. For performance alerts and trending, OnCommand Performance Manager capabilities are now integrated into the OCUM dashboard. This allows performance events to be consolidated into OCUM, and allows the storage administrator to observe more details of a performance event through the central OCUM interface. This activity familiarizes you with the overall interface of OnCommand Unified Manager. The tasks you will perform in this activity are listed below: Tasks Log into OnCommand Unified Manager. Review the Dashboard. View Information Across multiple storage clusters. View information at an individual cluster level. View information down at a volume level Interface Exercise These steps help provide a view into the details available on the OCUM Dashboard. 1. Open Chrome. The default home page is set to 2. Click Advanced. 8

9 2 Figure 4-1: 3. Click Proceed to ocum.demo.netapp.com. 9

10 3 Figure 4-2: 4. Login to OCUM as admin. 5. Enter Netapp1! for the password. 6. Click Sign In. 10

11 4 5 6 Figure 4-3: 7. The Unified Manager dashboard is displayed. The dashboard provides an overall look at the health of the storage environment managed by OCUM. 8. The Unified Manager dashboard overview includes four major sections: Availability Any events related to storage availability will show up in this section. Events included here are down network interfaces, down cluster interconnects, or missing lun paths. A cluster node that no longer has spare disks available would also be reported here. Capacity Aggregate, volume, and LUN capacity issues are reported in this section. Also included are capacity trending events that alert you if a particular storage object is anticipated to fill up in the near future (The time until full thresholds are configurable). Performance While OCUM collects data at 15 minute intervals, performance events are collected at 5 minute intervals. Baseline performance data is collected on storage objects, and predictive analysis is performend when the access patterns vary from the norm. This lab does not go into the details of performance capabilities, except to explain that the events OPM generates will show up in this section of the OCUM dashboard. Protection Data protection mirror or vault relationships are monitored to insure compliance with the desired update frequencies for each relationship. If the data in the mirror or vault is delayed by more than the allowed lag time, OCUM will show an event in this section. The Workflow Automator services are integrated with OCUM to enable you to correct data protection events without having to leave the OCUM interface. 9. Take a look at the cluster level. Click on the 2 under the Clusters graph in the Availability tile of the dashboard. 11

12 9 Figure 4-4: 10. Click on the name cluster1. 10 Figure 4-5: 11. The default view of the cluster is from an overall health perspective. Notice the overall health is green. 12. Take time to click on each of the tabs to view the information provided for the selected cluster. 13. You can also view the cluster from a performance perspective. Click the Switch to performance view check box to select that view. 12

13 Note: Due to lack of an active load, the performance view is not covered in this lab Figure 4-6: Now look at the environment at a volume level to show management can be across multiple storage systems. 14. On the left menu click on Health > Volumes. This provides a summary of all volumes being managed by OCUM regardless of which cluster they reside on. You can see which aggregate a volume is contained in, as well as which SVM is serving the volume. Note: You can export the displayed information to a CSV file by clicking Export on the upper right. 15. You can filter this view by selecting the filter criteria on the left. For example, under Protection Role you could select Unprotected to see all of the volumes that are not currently protected, in order to set up protection relationships for them. 13

14 14 15 Figure 4-7: 16. You may want to take a moment to return to the Dashboard and explore information at the cluster, SVM, or aggregate level as well. This activity illustrates how the OnCommand Unified Manager interface can provide summary and detailed level health and performance information across multiple clusters, and enable effective management of storage resources at any level. 4.2 Data Protection Relationships Overview OnCommand Unified Manager provides the ability to monitor and manage existing data protection relationships across multiple storage clusters. This is important to make sure the relationship updates successfully occur at the necessary frequency for the desired level of protection. OCUM can also be integrated with OnCommand Workflow Automation to create data protection relationships. This activity familiarizes you with OnCommand Unified Manager ability to monitor and manage data protection relationships, and respond to issues that may affect data protection. The tasks you will perform in this activity are listed below: Tasks Log into OCUM and view the overall protection health for the storage managed by Unified manager. View the existing protection relationships across all storage clusters. Investigate a problem with a data protection relationship. Take corrective action to resolve the problem. As you click down into an event to get more details, note the other information present in OCUM. Each objectspecific page in OCUM contains a wealth of collateral information related to that object, including links to those related objects. 14

15 4.2.1 Data Protection Relationships Exercise 1. If you have not already logged into OCUM, log in and view the dashboard. 2. Note that in the Protection tile of the dashboard, there is an event on the lag status graph. This is a data protection lag event on one of nine data protection relationships. 2 3 Figure 4-8: 3. To get a closer look at this issue, click on the 9 just below the red bar graph display where it shows 9 total Protection Lag Status indicators. This will bring us to the listing of all data protection relationships currently being managed by Unified Manager. Take a moment to note the information available for each relationship. 4. Find the entry with the error indicator in the Lag Status column. 5. The volume effected by this error is finance. 4 5 Figure 4-9: 15

16 6. Scroll to the right and find the Schedule column. Notice there is no update schedule associated with the finance volume. This is the reason for the Lag Status error. The volume was created and a SnapMirror data protection relationship was initialized; however, the mirror is now lagging behind the source volume due to the missing update schedule. To correct the error, a schedule has to be applied to the volume, and an on-demand update of the mirror relationship must be performed. 7. Click the svm4_finance_mirror Destination Volume name. 6 7 Figure 4-10: 8. Click Actions > Relationship > Edit. 8 Figure 4-11: 9. Click the SnapMirror Schedule drop down menu, and select daily. 10. Click Submit. 16

17 9 10 Figure 4-12: 11. At the completion of the SnapMirror modification job, the Schedule field for the modified relationship should now contain Daily. This should take 30 seconds or so. 12. Click to select the newly modified relationship for the finance volume. 13. Click Initialize/Update Figure 4-13: 14. On the Init/Update Relationships dialog box, click Submit. 17

18 14 Figure 4-14: 15. A prompt is displayed to view job status details. Click View Details 15 Figure 4-15: 16. The Job status is displayed. Click Refresh to update the status and wait for Complete. 16 Figure 4-16: 17. Select Dashboard > Overviewfrom the menu on the left. 18

19 18 17 Figure 4-17: 18. Notice the Protection status section of the Dashboard now shows all green indicators. In this activity you viewed the health of data protection across all storage systems managed by OCUM, responded to a problem, and took the necessary corrective action all from a single console. 4.3 Annotations and Groups Overview Even in small IT environments, managing storage objects in a meaningful way is a challenge. Scaling the number and size of these objects out over many nodes, clusters, and geographically separate datacenters only adds complexity to storage management. OnCommand Unified Manager s Annotations and Groups allow a storage architect to better organize these storage objects. When set up properly, Annotations allow you to instantly understand the business impacts of an event, or alert in OCUM. Administrators can associate any storage object to an annotation without the need to apply rule-based annotation. Groups allow an action to be applied to all storage objects that are a member of that group, thus eliminating repetitive tasks on similar objects and improving consistency of management. These features also allow for quick tailoring of reports generated from OCUM. In this lab environment, Annotations are used to specify where a storage object resides, which application the storage object is supporting, and which business units rely on the storage object for daily activities. Annotations can be manually applied to a storage object; however, there are often some simple rules you can use to automatically annotate an object depending on its name, which Storage Virtual Machine is managing it, or which cluster it is in. The following lab activity explores the defined annotations as well as the rules that are in place to associate the annotations with the related storage objects. Tasks Open OCUM and Administrative Menu and locate access to annotations and groups Review default annotations and annotation rules and how they can be used to organize storage objects and automatically assign annotations to new objects as they are created Select a volume storage object and manually assign an annotation. 19

20 Tasks View the default groups how rules determine membership of a group and actions determine what operations can be performed across all group members Annotations Exercise 1. If you have not already logged into OCUM, log in and view the dashboard. 2. Click on the gear icon at the upper right to go to the Administrative options menu. 2 Figure 4-18: 3. There are four default annotations in OCUM, each with one or more rules. Additional annotations can be created. If not already selected, click on theapplication annotation. Under Values you see that this environment has been configured with four possible values for an application. These values are configured by the OCUM administrator, and can be anything that makes sense for organizing storage objects. As you can see there are already Application annotations, or values for Exchange, Oracle, File Shares, etc. 4. Click Manage Rules. 20

21 3 4 Figure 4-19: This is a list of annotation rules that define which objects will have the Application annotation values. 5. Select the Exchange annotation rule for volume objects. Note: There is also an Exchange rule that applies to SVM objects. 6. Click Edit. 6 5 Figure 4-20: While annotations can be manually applied to any object, this rule shows how annotations can be dynamically applied to all current and future storage objects that match the rule. In this example, SVM3 and SVM7 are Storage Virtual Machines that are dedicated to serving Exchange data. As a result, all volume objects owned by either SVM3 or SVM7 will automatically have the Application annotation applied with a value of Exchange. This eases the management burden of making sure new objects are properly categorized. 7. Click Cancel. 21

22 7 Figure 4-21: 8. Take time to edit the other annotation rules to see how their conditions differ. The Exchange and File_Share values are applied to objects owned by certain SVMs, while the Oracle and vsphere values are applied by matching a part of the object name. Note: As was the case with annotations, new annotation rules can be created to meet organizational needs. 22

23 8 Figure 4-22: 9. Click the Annotations tab to go back and investigate the BU (Business Unit) and Geography (Datacenter Location) annotation definitions. 9 Figure 4-23: OCUM Groups can utilize Annotations within the group rules, as you will see in the next section. Administrators can associate any storage object to an annotation without the need to apply rule based annotation. The following steps manually assign a annotation to a volume. 10. Click on the Home icon on the upper left. 23

24 10 Figure 4-24: 11. Navigate to Health > Volumes. 12. Click on the mgmt_datastore volume Figure 4-25: 13. On the volume details page of mgmt_datastore, select Actions > Annotate. Note: You can only assign a storage object to an available annotation. You cannot create a new annotation with this process. To create a new annotation, navigate to Administration > Annotations, click the Add Annotation button, and complete the form. 24

25 13 Figure 4-26: 14. On the Annotate Volumes window, select the data-priority > high annotation and value. This annotation is applied to storage objects that contain high-priority data. For example, objects that are hosting business applications can be considered high priority. 15. Click on Apply. 25

26 14 15 Figure 4-27: 16. Notice this new annotation is now associated with the volume. You can also see that there are two other annotations that have been automatically applied to this volume. vsphere is associated with this volume because its name contains the string datastore, and LA is associated with this volume because the volume is owned by cluster1. Note: If these automatic associations are not clear, review the annotation rules using the steps in the previous section. 26

27 16 Figure 4-28: Now that you have reviewed Annotations and their purpose, along with how they can be automatically applied to new storage objects, take a look at how groups can simplify storage management Groups Exercise The goal behind groups is to define a collection of objects that a single action can be applied to. Because the action is applied across all objects in a group, the members of that group should have very similar characteristics. They could be all file share volumes, all volumes containing LUNs, all vsphere datastore volumes, all SVM root volumes, etc. In this lab environment, objects have been defined in the following groups: Database_LUNs Database_NFS SVM_root_vols Unstructured_data VM_storage This activity focuses on applying a new volume threshold to all members of the SVM_root_vols object group. 1. Click on the gear icon at the upper right to go to the Administrative options menu. 2. Select Groups in the Management section on the left menu. Notice that the groups in this environment are applied to only Volume objects. Clusters and SVMs can also be members of a group. 3. Click SVM_root_vols. 27

28 2 3 Figure 4-29: You can see in this view that the SVM_root_vols group has an associated rule as well as an associated action. Note: A rule is a condition or a set of conditions that must be met for an object to be a member of that group. 4. Click Manage Group Rules to discover how objects become members of this group. 4 Figure 4-30: 5. Click the SVM_root_vols name to highlight the entry. 6. Click Edit. 28

29 6 5 Figure 4-31: This group rule is very simple, as it matches any volume containing _root in its name. Remember that the objects allowed in a group are clusters, SVMs, and volumes. The Target Object Type on this rule is set to Volume. The Conditions section allows for both and and or conditions to be set in order to create very specific rules that include multiple conditions. 7. Click Cancel. 29

30 7 Figure 4-32: 8. Click Group Actions to view the actions that have been established and can be applied to a group. 9. Click on the name of the action to highlight the entry. 10. Click Edit. 30

31 Figure 4-33: This group action overrides the global capacity threshold values. Since the volumes in this group are SVM root volumes, they are very small, and are not anticipated to grow much. Note: In certain conditions, log files can build up and require clean up, or increasing the volume size may be necessary, so it is still a good practice to alert when they get full. 11. Click Cancel. 31

32 11 Figure 4-34: Note: Take time to investigate the other groups, and what conditions are required for objects to be in those groups. Because rules are used to populate the groups, any new storage objects that are created with those same conditions will automatically be added to the group, and the associated actions will apply to them as well. In this lab activity, you have reviewed annotations and annotation rules, and how they can be used to organize storage objects and automatically assign annotations to new objects as they are created. You also reviewed how groups can provide consistency across like storage objects as they are created. Both lead to more effective and consistent storage management. 4.4 Favorites Page Overview The Favorites dashboard provides faster access to critical storage objects. Cluster, aggregate and volumes can be added to the favorites dashboard. This page intelligently provides relevant information based on the storage object type. For example, an aggregate would display capacity utilization and performance statistics, whereas a volume will display capacity utilization, protection, and performance statistics. In this activity you look at the default favorites that are included with OCUM, view the information available for a favorite, and finally add a favorite to your Favorites dashboard. 32

33 Tasks Review currently installed Favorites Review advantages of using Favorites and ability to easily get more details Add a new Favorite Favorites Page Exercise 1. If you have not already logged into OCUM, log in and view the dashboard. 2. Select Favorites on the left menu. 2 Figure 4-35: Note: Notice that for each favorite item on this page there are different details provided in this view that are closely related to the object type. Take a moment to examine the page. At a quick glance you can see that the engineering volume does not have a data protection relationship associated with it. This is just one example of how important details will pop up on this view of items you deem to be Favorite. 3. Hover the cursor over one of the volume favorites to get more details in terms of on which cluster and SVM it is located. 33

34 3 Figure 4-36: 4. Navigate to a resource that you might want to add to the Favorites page. Select Health > Volumes from the menu on the left. 4 Figure 4-37: Note: You can add Aggregates, Volumes, and Cluster objects as favorites. For this example, you are configuring a volume as a favorite. 5. Click on volume vdi_datastore. 34

35 5 Figure 4-38: 6. While on the Volume Details page, click the star to add this volume to the Favorites page. 7. Now go back to the Favorites page to view the newly added object. 7 6 Figure 4-39: 8. Notice the vdi_datastore volume is now listed on the favorites page. See how simple it is to populate this page with the most important storage objects for quick access to their associated details! 35

36 8 Figure 4-40: In this activity you have seen OCUM Favorites and the details viewed for each. You have also added a Favorite to the dashboard so that the status details of critical objects can be easily monitored. 4.5 Capacity and Utilization Overview The key to effective capacity management is being proactive. On-Command Unified Manager enables that by providing early warning of potential capacity issues before they become critical, and reports at an aggregate or volume level of daily growth rates and "days to full" statistics. Through the use of Annotations, capacity utilization can be monitored at a application, business unit, or geographic level. Note: Reports and Annotations are covered in other activities of this lab. The Capacity pane on the Overview dashboard, displays, as a graph, information about the capacity of aggregates and storage virtual machines (SVMs) that are monitored by Unified Manager. The storage objects are categorized as Healthy, At Risk, or Have Incidents. For example, the status of an aggregate whose used capacity has reached the full threshold value is displayed as At Risk. This pane also displays the number of storage objects in each of the categories Capacity and Utilization Exercise In this activity you will locate the details for the yellow capacity event, and resolve the issue. 1. If you have not already logged into OCUM, log in and navigate to Dashboards > Overview on the left. 2. Look at the error, which is yellow under the Capacity section below, and click on the 1 above the yellow SVMs bar graph. 36

37 1 2 Figure 4-41: 3. The capacity error is related to the sales_east volume being full. 4. This time acknowledge the error before correcting it. Click the checkbox on the left side of this entry. 5. Click Acknowledge Figure 4-42: 6. Notice the State changed for this event. This will communicate to other OCUM users that someone is working on the issue. 7. To resolve the event, click on the source volume name svm8:/sales_east. 6 7 Figure 4-43: 37

38 8. Notice that this volume has a Full Threshold set to 40%. Since the volume has sufficient space, adjust the threshold level to a more appropriate value. 9. Click Actions > Edit Thresholds. 9 8 Figure 4-44: 10. Click Restore to Defaults to remove the custom thresholds for this volume, and set them back to the global capacity threshold defaults. 38

39 10 Figure 4-45: 11. Notice the Space Nearly Full, and Space Full thresholds that will be applied with this change. 12. Click OK. 39

40 11 12 Figure 4-46: 13. Click Close on the Success confirmation window. 13 Figure 4-47: 14. Navigate to Dashboards > Overview on the left. Note: The yellow indicator on the Capacity pane in the SVMs graph may take a few minutes to show the new (green) status. You can either wait for this update on the dashboard, or continue with the next activity and notice it turn green as you finish other tasks. 40

41 14 Figure 4-48: 15. Now that you resolved the issue, mark the event as Resolved. Click on Events on the left. 16. Click the checkbox on the left of the event, and click Mark as Resolved Figure 4-49: In this activity you discovered a capacity issue with one of the SVMs, acknowledged the event to let others know you were working on it, then quickly corrected the problem. This was all done from a single tool. This activity showed quick and proactive storage management at work. 4.6 Alerts Overview In order to enable quick response to events when they occur, and minimize potential disruption to users, OnCommand Unified Manager can be configured to send notifications that alert you about events in your environment. These notifications can be in the form of SNMP traps, or s to appropriate individuals or groups. In addition to SNMP traps and notifications, an alert can also trigger a pre-defined script. These customer written scripts can provide additional information about the event, or possibly take corrective action. The script must be written in Perl, Shell, PowerShell, or be a batch file. The OCUM Alert can pass the following arguments to the script being called: eventid, eventsourceid, eventsourcename, eventsourcetype, eventstate, eventargs. When you create an alert you will define: 41 What resources this alert will apply to. What category and type of event(s) to which it applies.

42 What action(s) are taken. ( , SNMP trap, script) Alerts Exercise In the following activity you are going to create an alert based on data aggregate events. 1. If you have not already logged into OCUM, log in, and view the dashboard. 2. On the left menu click Health > Aggregate. 2 Figure 4-50: 3. Click the aggr2 aggregate. 3 Figure 4-51: 4. Click Actions > Add Alert. 42

43 4 Figure 4-52: 5. Name the alert Data Aggregate Alert. 6. Click Resources. 6 5 Figure 4-53: Note: The aggr2 aggregate is already in the Selected Resources list because that was the context you were in prior to adding a new alert. From this view, you can continue to add an alert for the one object you selected (aggr2), or you can modify the alert to include/exclude other objects. Because this activity is mainly focused on data aggregate events, you are going to remove the specific object, add all aggregates, then exclude the non-data aggregates (aggr0). 7. Click on the double-left arrow <<- to remove all currently selected aggregates (aggr2). 8. Click the << All Aggregates >> resource. 43

44 9. Click the right arrow -> to move it under Selected Resources Figure 4-54: 10. Click the Exclude tab. Note: The Exclude tab will be greyed out until you put << All Aggregates >> in the selected resource list. 11. Enter aggr0 in the Name contains field, and click Add. 44

45 10 11 Figure 4-55: At this point you have specified that this alert applies to all data aggregates. Now you need to specify which events, and the level of severity, this alert will be subscribed to. 12. Click Events. 13. Select both Critical and Error. 14. Click the double-right arrow - >> to add all items to the Selected Events. 45

46 Figure 4-56: This specifies that this alert applies to all Critical and Error events for all non-data aggregates. Now specify what notification or action will be taken when one of these events occur. 15. Click Actions. 16. Click the Alert these users: drop down list, and select admin. Note: This can be a user, or a group of users. 17. Set the Notification Frequency to Remind every 15 minutes. 18. Click Save. 46

47 Figure 4-57: Note: You can also attach a script for remedial actions on a type of event. To perform this, simply add the script in the Select script to execute. You are not actually configuring this in this session. 19. To view this new alert, along with all other defined alerts, in the left menu click Configuration > Alerting. Note: Notice that this is the only alert that has been created in this environment to date. 20. Select the alert, and you will see the alert details appear at the bottom of the page. 47

48 20 19 Figure 4-58: You have just extended Unified Manager's event detection capability to provide alert notification for those events that are most critical to storage operations. This enables administrators to react quickly and minimize or eliminate disruption to users. 4.7 Reporting Overview While Events and Alerts are an important part of OnCommand Unified Manager communicating storage related issues to the administrator, OCUM Reports provide information that can help identify potential issues, and give the administrator time to be proactive and prevent issues from occuring. Capacity trending reports can help predict how long a LUN, volume, or aggregate can grow at its current rate before becoming full. Other report views help communicate to business units and executives how the current storage investment is being utilized. Because this lab environment does not add new data to the LUNs and volumes it contains, the capacity trending data will not be of much interest. The sample data that exists within the storage objects was placed there on a single day in the past, and has not been added to since then. Given this fact, OCUM does not anticipate any of the volumes in this lab to become full in the near future. In this activity you perform the following activities: Log into OnCommand Unified Manager. Run and on-demand report and share it. Create a schedule of reports to be run on a daily basis Reporting Exercise 1. If you have not already logged into OCUM, log in and view the dashboard. 48

49 2. In the left menu, click Reports. 2 Figure 4-59: 3. You will see that there are four categories of built-in reports: Capacity Utilization, Operational Reports, Inventory Reports, and Data Protection Reports. Note: There is also the ability to create custom reports and import them into OCUM. This is outside the scope of this lab. Consult the References section for additional information. 4. Under "Capacity Utilization", locate the Volume Capacity and Utilization report, click Run Report. 4 Figure 4-60: 5. Scroll from left to right in order to see all of the columns of data available in the report. 49

50 6. Click Actions > Share. 6 5 Figure 4-61: Note: These reports can also be customized as shown on the right side of the report. Customization is outside the scope of this lab. 7. When you share a report, you can enter a list of addresses for recipients, define the subject line, and select from five different export formats: PDF, XHTML, CSV, Excel, and Text. 8.
