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 SVC 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.
