2 VMAX Management h) Create the masking views. VMAX Management In a Cisco UCS Director EMC VMAX account you manage the following pools, groups, devices, and views: Thin pools Create/delete, expand, bind/unbind, and view details Devices data devices, thin devices, and meta devices Initiator groups Create/delete, rename, add/remove initiator, replace initiator, set override flags, and view details Storage groups Create/delete, rename, add/remove device, associate/disassociate FAST policy, and view details Port groups Create/delete, rename, add/remove port, and view details Masking views Create/delete, rename, and view details Thin Pools A new thin pool requires a unique name. Click buttons on the Thin Pools tab for the following actions: Create Create a thin pool. Expand Bind Unbind Delete Expand a thin pool. Bind a thin pool. Unbind a thin pool. View detailed reports on a thin pool. Delete a thin pool. 2 OL

3 Creating A Thin Pool Creating A Thin Pool An EMC VMAX thin pool is a collection of data devices that provide storage capacity for thin devices. On the Storage pane, choose the VMAX data center. Click the Thin Pools tab. In the Create Thin Pool dialog box, enter a name in the Thin Pool field. Click Submit. Data Devices A Symmetrix device is either a data device or a thin device. The Data Devices tab provides the following actions: Create Delete Create a data device. Delete a data device. View detailed reports on a data device. OL

4 Creating a Data Device Creating a Data Device On the Storage pane, choose the VMAX system. Click the Data Devices tab. In the Create Data Device dialog box, complete the following fields: Device Count field Capacity (GB) field Emulation drop-down list Configuration field Disk Group field The data device count. The capacity, in gigabytes. Choose the Emulation type for the data device. Choose the Configuration for the data device. The disk group name. 0 Click Submit. What to Do Next You can select a device and click to see the drill-down report. Thin Devices A Symmetrix device is either a thin device or a data device. The maximum size of a VMAX thin device (TDEV) is ~240 GB. Note If you want to create a TDEV greater than this size, combine TDEVs to form a meta device. Each TDEV can be part of only one meta device. The Thin Devices tab provides the following actions: 4 OL

5 Creating a Thin Device Create Delete Create a thin device. Delete a thin device. View detailed reports on a thin device. There is no Rename action for a TDEV. The device name is unique and remains the same even if the TDEV becomes a meta device, and vice versa. Creating a Thin Device On the Storage pane, choose the VMAX system. Click the Thin Devices tab. In the Create Thin Device dialog box, complete the following fields: Device Count field Capacity (GB) field Emulation drop-down list Bind to Thin Pool field Pre-allocate 100% check box The thin device count. The capacity, in gigabytes. Choose the Emulation type for the thin device. Continue to 0. Check this check box to pre-allocate 100% of storage for the thin device. 0 1 Choose either None, or choose a thin pool to bind this device to from the list. Click Submit. What to Do Next You can select a device and click to see the drill-down report. OL

6 Meta Devices Meta Devices A meta device enables you to aggregate thin devices to increase device size. You can create a meta device with a thin device as the head, and other thin devices as members. The total meta device size is the combination of the head size, and all the member device sizes. Note There is no Delete action for a meta device. Removing the members from a meta device results in a thin device. The Meta Devices tab provides the following actions: Create Meta Create a new meta device. View detailed reports on a meta member device. Creating a Meta Device On the Storage pane, choose the VMAX system. Click the Meta Devices tab. Click Create Meta. In the Create Meta Device dialog box, complete the following fields: Select Head Thin Device field Meta Type drop-down list Select Member Device(s) field Click Select. Continue to 0. Choose the Meta Type type. Click Select. Continue to 1. 6 OL

7 Initiator Groups In the Select dialog box, choose the head thin device, and click Select. In the Select Items dialog box, click Check All, Check None, or check the boxes for individual devices. Click Select. In the Create Meta Device dialog box, click Submit. Initiator Groups A VMAX initiator group is a collection of host bus adapters (HBAs) that work together. Initiator groups that contain other initiator groups are considered cascaded initiator groups. You can add, replace, or remove host initiators for an initiator group. A new initiator group requires the following parameters: Initiator group type Initiator group name Initiator type Initiator name Consistent LUN (on/off) Click buttons on the Initiator Groups tab for the following actions: Create Rename Delete Add Initiator Replace Initiator Remove Initiator Override Flags Create an initiator group. Rename an initiator group. Delete an initiator group. Add a host initiator. Replace a host initiator. Remove a host initiator. Override flags for volume set addressing, common serial number, disable Q rest on UA, SPC2 protocol version, environment set, AS400, avoid reset broadcast, open VMS, SSCI support1, and SCS13. View detailed reports on an initator group. OL

8 Creating an Initiator Group Creating an Initiator Group On the Storage pane, choose the VMAX system. Click the Initiator Group tab. In the Create Initiator Group dialog box, complete the following fields: Initiator Group Type drop-down list Initiator Group field Initiator Type drop-down list Initiator field Consistent LUN check box Choose the Initiator Group Type (Standard or Cascaded). Standard is the default initiator group type. If you chose Cascaded, continue to 0. The initiator group name. Choose the initiator type (iscsi or FCP). iscsi is the default initiator type. The initiator name. Check this check box if you want to use consistent LUN. Unchecked is the default. 0 For a cascaded initiator group, complete the following fields: Select Parent Initiator Group field Select Child Initiator Group field Select the parent initiator group. Select the child initiator group. 1 Click Submit. Storage Groups A VMAX storage group is a collection of Symmetrix logical volumes that are used by an application, a server, or a collection of servers. 8 OL

9 Creating an Empty Storage Group Storage groups present storage to hosts and are also used for FAST policies. In Cisco UCS Director you can create VMAX storage groups that are either Empty or Cascaded. A cascaded group can be contained within a masking view to present storage resources to an entire cluster. The Storage Groups tab provides the following actions: Create Rename Delete Add Device Remove Device Associate FAST Policy Disassociate FAST Policy Create a storage group. Rename a selected storage group. Delete a storage group. Add a new device to a selected storage group. Remove a device from a storage group. Associate a FAST policy with a selected storage group. Disassociate a FAST policy from a selected storage group. View detailed reports on a storage group. Creating an Empty Storage Group On the Storage pane, choose the VMAX data center. Click the Storage Groups tab. In the Create Storage Group dialog box, complete the following fields: Storage Group Type drop-down list Storage Group field Accept the default option Empty Storage Group. The storage group name. Click Submit. OL

10 Creating a Cascaded Storage Group What to Do Next Add devices and associate FAST policies to the storage group. Creating a Cascaded Storage Group A cascaded storage group can contain one or more child storage groups. On the Storage pane, choose the VMAX data center. Click the Storage Groups tab. In the Create Storage Group dialog box, complete the following fields: Storage Group Type drop-down list Select Parent Storage Group field Child Storage Group field Choose Cascaded Storage Group. Choose the parent storage group. Choose the child storage group. Click Submit. What to Do Next Add devices and associate FAST policies to the storage group. Port Groups A VMAX port group is a collection of front-end ports. The Port Groups tab provides the following actions: Create Rename Delete Create a new port group. Rename a port group. Delete a port group. 10 OL

11 Creating a Port Group Add Port Remove Port Add a new port to a selected group. Remove a port from a group. View detailed reports on a selected port group. Creating a Port Group On the Storage pane, choose the VMAX data center. Click the Port Groups tab. In the Create Port Group dialog box, complete the following fields: Port Group field Select Port Group field The port group name. Click Select. Continue to. 0 1 In the Select Items dialog box, choose the VMAX port group. Click Select. In the Create Port Group dialog box, click Submit. Masking Views VMAX designates three types of auto-provisioning groups: storage groups, port groups, and initiator groups. These three groups work together as a masking view. The masking view ensures that the target initiators (in an initiator group) can access the target storage resources (in a storage group) by means of the target ports (in a port group). Masking views are also useful for making changes to storage presentation. Changes to groups that belong to a masking view, such as adding a device or port, are automatically reflected in the masking view. OL

12 Creating a Masking View Click buttons on the Masking Views tab for the following actions: Create Rename Delete Create a masking view. Rename a masking view. View detailed reports on a masking view. Delete a masking view. Creating a Masking View Before You Begin You must create a storage group, initiator group, host LUN, and port group in the system. You must attach devices to the storage group. On the Storage pane, choose the VMAX data center. Click the Masking Views tab. In the Create Masking Views dialog box, complete the following fields: Masking View field Select Storage Group field Host LUN ID field Select Initiator Group field Select Port Group field The masking view name. Choose the Storage Group. The host LUN ID. Note If a LUN ID is not specified, the Host LUN ID is autogenerated. Choose the Initiator Group. Choose the Port Group. Click Submit. 12 OL
