8 Scheduled downtime: Backups Online point in time backups 6.1 Save-While-Active (SWA) synchronized across libraries and IFS objects Single checkpoint to ensure library and IFS data saved in consistent state STRSAVSYNC command in 6.1 Full System Copy Services Manager (FSCS) from IBM STG Lab Services Enables automated, full system backup without ending user jobs Supports SVC/V7000, DS8000 and XIV external storage See Full System Copy Services Manager section of IBM i Advanced Copy Services developerworks Wiki Save IASP mirror copy (FlashCopy or detached geographic mirror) For PowerHA environments FlashCopy with ICSM (IASP Copy Services Manager) from IBM STG Lab Services enables automatically creating point in time copies of an IASP on DS8000 or SVC/V7000/V3700. See ICSM - FlashCopy section of IBM i Advanced Copy Services developerworks Wiki 7

9 FlashCopy overview Prod LPAR IASP DS8000, SVC, Storwize, V840/V9000 *SYSBAS FlashCopy LPAR-2 IASP Tape Backup *SYSBAS (backup) FlashCopy is a point-in-time-copy of external storage logical volumes that can be established very quickly and with minimal or no disruption or resource on the production LPAR IASP based or Full System solution FlashCopy options full copy, no copy Space Efficient FlashCopy volumes can reduce FlashCopy storage by 70-80% Use with 6.1 Quiesce to eliminate IASP vary off or LPAR shut down, journal for object and data integrity of flashcopy Automate with IASP Copy Services Manager for PowerHA on i or with Full System Copy Services Manager" (FSCS) from IBM STG Lab Services Integration with BRMS Ideal for off-line backup solutions 8

10 PowerHA FlashCopy options IBM i can leverage FlashCopy to: Create a copy of an IASP for backup Create a full system copy for backup Recommendation is: Vary off the IASP or power down the system before taking the Flash Known as a cold Flash is the best way to guarantee complete data integrity IBM i 6.1 added support for the Quiesce of IASP Known as a warm Flash suspends transactions & operations to ensure that as much in-flight data as possible is written to disk Places transactions at database boundaries if possible Best when used with applications running commitment control Requires a recovery vary-on of the IASP. 7.1 and later supports Quiesce with VIOS storage pools 9

11 What is Full System FlashCopy? A set of tools provided by IBM PowerHA Lab Services for years Originally marketed as Full System FlashCopy Toolkit (FSFC Toolkit) Rebranded in 2014 as Full System Copy Services Manager (FSCSM) Rebranded in 2016 as a feature under Full System Manager Full System FlashCopy (FSFC) Leverages FlashCopy features on IBM storage subystems Presents a full system copy of a production system (LIC and O/S) to another set of hardware resources Intended to be a BACKUP SOLUTION Automates the end-to-end processes required to achieve a full system backup of production system(s) 10

12 Who are the target customers for Full System FlashCopy? Customers unable (or un-willing) to implement PowerHA requirement for independent auxiliary storage pools (IASPs) for any reason Time constraints Resource limitations Most Budgetary restraints common Application-specific technical obstacles reason Customers with limited down-time windows on production systems Customers desiring easier recovery options for full system outages Customers needing alternative options to software-based strategies Stopping replication, allowing changes to catch up, performing backups primarily on application data only, resuming replication Customers wanting a temporary production test environment to use until the next backup is performed 11

13 Features and Benefits of Full System FlashCopy Provides full system backup of production partition with minimal (or no) interruption to production workload Provides better RPO of full system data (more frequent backups) Simplifies recovery process with full system backup on one (or few) tape(s) Supported with wide variety of IBM external storage DS8000 Family Spectrum/Storwize (SVC-based) - V3700, V5000, V7000, V9000, Flash Systems XIV Can manage multiple environments from one controlling partition Automates end-to-end process via single command Easy, centralized management of many steps on many systems Extensive logging for time-tracking and error resolution Integrates well with BRMS environments (but not required) 12

14 Scheduled downtime: Backups Backup Usability/Automation 7.1 and 7.2 BRMS enhancements Improved functions for managing backups, media, backup history, and recoveries See News section of BRMS developerworks Wiki BRMS Enterprise Function Monitor backup operations for all your BRMS systems from a central site Provides common spot for recovery reports, dashboard for all systems, ability to get status on a control group run... all from a central hub. 7.2 enhancements (not PTFed back to IBM i 7.1) Auto refresh of Hub s node status (dashboard) via new Q1ABRMENT subsystem PRTRPTBRM support Failed Control Group View to debug problems faster See BRMS Enterprise section of BRMS developerworks Wiki for details See BRMS Enterprise Enhancements Redpaper 13

26 Live partition mobility Move a running partition from one Power7/8 server to another with no application downtime Movement to a different server with no loss of service Virtualized SAN SAN and and N etwork Infrastructure Reduce planned downtime by moving workloads to another server during system maintenance Rebalance processing power across servers when and where you need it Live Partition Mobility requires the purchase of the optional PowerVM Enterprise Edition 25

27 Partition mobility: Active and Inactive LPARs Active Partition Mobility Active Partition Migration is the actual movement of a running LPAR from one physical machine to another without disrupting the operation of the OS and applications running in that LPAR. Applicability Workload consolidation (e.g. many to one) Workload balancing (e.g. move to larger system) Planned CEC outages for maintenance/upgrades Impending CEC outages (e.g. hardware warning received) Ability to move from Power7 servers to Power8 servers without an outage Inactive Partition Mobility Inactive Partition Migration transfers a partition that is logically powered off (not running) from one system to another. Suspended Partition Mobility Suspended Partition Migration transfers a partition that is suspended from one system to another. 26

29 Unscheduled Downtime: Recovery Time IPL performance improvements 7.1/7.2 Access Path recovery and Journal synchronization Significant improvement in some environments (including IASP vary on), particularly where large Access Paths are rebuilt unexpectedly instead of recovered from the journal 7.1 Cumulative PTF package C and/or DB2 PTF Group SF99701 Level Cumulative PTF package C and/or DB2 PTF Group SF99702 Level Main Store Dump (MSD) improvements Storage Management Subset Directory Recovery (SRC C ) on systems with very large (>4GB) permanent directories Smart Dump for User-Initiated MSDs and XPF-related crashes Prior to 7.2, these were always Full Dumps requiring all main store to be dumped Smart dumps require only a subset (around 10%) of main storage to be copied to disk which greatly reduces the time needed for this MSD step New message on Copy Status screen indicates when Smart (subset) dump vs. Full dump being copied (factor into IPL recovery time/decision making) Best Practices for Managing Time Needed for Main Storage Dump (MSD) Technote Latest recommendations, enhancements, and PTFs to help manage and reduce time required for a MSD 28

30 Main Store Dump Smart-Dump Indicator Prior to 7.1, when copying a Main Store Dump to disk, SRC C6xx4404 is displayed where xx is the percent completed for copying the dump In 7.1 (and with PTF MF58168), the SRC is later changed to indicate what type of dump is being copied (xx still displays the percent complete): Full dump: SRC C6xx1404: Copying a compressed full dump SRC C6xx2404: Copying a uncompressed full dump Subset dump ("smart dump"): Much shorter/faster than a full dump! SRC C6xx3404: Copying a uncompressed subset dump SRC C6xx4404: Copying a compressed subset dump In 7.2, a message is displayed on the MSD copy status screen while the copy is in progress indicating the type of dump being copied and the percent complete To see this information, press Enter on the MSD summary screen ("Main Storage Dump Occurred" screen), select "Work with current main storage dump (MSD)" on the MSD Manager screen, and then press F11=Copy status 29

31 Unscheduled Downtime: Recovery Time 7.1 TR4 Remote Restart Recover and reboot partition on another server after an unplanned server failure Similar prerequisites as for LPM (VIOS, external storage, etc.) Combine with Power Enterprise Pools for maximum flexibility/efficiency Requires either IBM Systems Director VMControl or HMC V8R8.1.0 (Simplified Remote Restart with HMC 8.820) Includes new command to initiate a Remote Restart operation (manually or automate using CLI/APIs) 30

32 Unscheduled downtime: Recovery time Restore Enhancements 7.2 Defer restore and journaling of dependent objects Also available as 7.1 PTF SI Option to not start journaling for restored objects New STRJRN parameter on restore command 7.1 New ALWOBJDIF(*COMPATIBLE) value on RSTLIB/RSTOBJ commands Essentially behaves like ALWOBJDIF(*ALL) in combination with ALWOBJDIF(*FILE) for database files (i.e., a single value that does what most people want to happen) 7.1 Fast Restore of Single Object 6.1 Restore logical and physical files in different libraries in any order 31

33 7.1 Fast restore of single object Save operations track position (physical location on tape) of each object New field returned for each object in Save OUTFILE or OUTPUT You must retain this positioning information for use during restore New restore POSITION parameter RSTLIB RSTOBJ and RST commands and APIs POSITION(*START) is default and gives existing behavior POSITION (hexadecimal value) allows you to pass the position for a single object to be restored Requires that sequence number SEQNBR also be specified Also supported for parallel restores Very significant performance improvements can result For example: Restoring last object from 1.1 million IFS object save went from about 22 minutes to less than 3 minutes. Backup Recovery Media Service (BRMS) uses this new support 32

34 Unscheduled downtime: Recovery time Journal management enhancements (since 6.1) Journal libraries and automatically journal new objects in the library 7.1 Object name filtering for automatic journaling (select/omit objects based on name) User can end journaling and then start journaling a file without closing file STRJRNxx/ENDJRNxx commands to start or end journaling all objects in a library DSPRCYAP/EDTRCYAP screens show which access paths are eligible for SMAPP protection but are not currently being protected User control over frequency of forcing changed objects to disk (journal recovery count) Choose faster runtime processing vs. faster IPL/vary on recovery after abnormal shutdown See Journal management > What's new topic in the Knowledge Center

35 Remote journal enhancements 7.2 Remote journal over secure sockets (SSL) support 7.1 Automatic restart of remote journaling if ended due to a recoverable comm error 7.1 Ability from source side to view number of retransmissions occurring for a remote journal connection Measurements of how far behind source system is at sending data to target (6.1 included measurements of how far behind target system is at receiving data from source) 7.1 Filtering and not sending journal entries that are not absolutely needed to the target 7.1 Improved WAN performance via larger buffer size (greater of 256KB or TCP send buffer size on source or TCP receive buffer size on target) Also available via PTFs v5r4m0 MF46358, v5r4m5 MF46359, v6r1m0 MF Use of data port services with up to 4 comm lines for greater resiliency 6.1 Validity checking to verify data received by target matches data sent from source 34
