Prerequisites

In order for SRM to run any operations on FlashArray-hosted datastores/RDMs, there are a few requirements:

1. FlashArray SRA version 3.1 or later
2. Replication must be configured on those volumes
3. Array managers must be configured
4. Array pairs protecting those volumes must be enabled
5. Volumes must be discovered by SRM
6. The volumes must be added to a protection group
7. The protection group must be in at least one recovery plan
8. Hosts and host groups must be pre-created on the recovery FlashArray for the target recovery clusters
9. Place volumes in protection groups for use with SRM protection groups and recovery plans. Using Hosts or Host Groups as placement for volumes to be protected by SRM has inconsistent behavior and support for this is best effort. Pure Storage is working to improve these workflows for a future release of the SRA when using host or host groups, but at this time Pure recommends avoiding using Host or Host Group placement for FlashArray protection groups

   There is no need to pre-create any recovery volumes or pre-connect anything to the recovery hosts on the FlashArray(s). The SRA automates the process of creating recovery volumes and connecting them to the appropriate host resources.

   Note:

   Everpure recommends always recovering all datastores in a pod together. While you can separate out different groups of datastores from the same pod into different SRM protection groups/recovery plans for testing, it is advisable to perform actual recoveries all together of everything in that pod. The reason for this is that for failback the pod must be un-stretched. If there are still applications running within the pod the unstretch operation will adversely affect their availability until the recovery is complete. For this reason, it is best to put non-SRM protected volumes in their own pod, or any datastores that might need to be failed over independently in their own pod.
