Configuring source and target volume backup settings
Source and target volume backup settings must be configured for the following recovery scenarios provided by VMware SRM version 5.0 and later:
- Planned failover
- Disaster recovery
To do this, configure Spectrum Virtualize
Family SRA to create FlashCopy® backups of the remote
copy source and target volumes by setting protectSource and
protectTarget to True in
sra.settings. (To learn how to update sra.settings, see
Updating the SRA configuration file.)
Note: For IBM Stretched Cluster and IBM HyperSwap, a stretched volume or a HyperSwap volume
does not have source or target, so the SRA will not create FlashCopy backups even if
protectSource and protectTarget are set to
True.
In addition, set the appropriate MDisk group IDs for sourceMDiskGroupID and
recoveryMDiskGroupID within sra.settings before completing
the update process. Also, be sure to set the appropriate testMDiskGroupID in
sra.settings before promoting target volumes to the VMware ESX server and
recovering VMs on them.
Note: If the Spectrum
Virtualize Family SRA fails to back up the source or target volumes, no warning message is
displayed. Check the backups on the storage system or check the messages in the SRM log files.
