Administrator Guide

• Promote the replica set to a recovery volume (and snapshots) on the secondary group and congure initiators to connect to the
recovery volume.
If the primary group becomes available, you can replicate the recovery volume to the primary group and then fail back to the
primary group, returning to the original conguration.
NOTE: Replication is used primarily for disaster recovery and does not take the place of a comprehensive backup
strategy.
You can manually delete replicas and replica sets that are no longer needed. You cannot delete the most recent, complete replica
from a replica set, but you can delete the entire replica set, which disables replication on the volume.
NOTE: For information about NAS replication options, refer to NAS Volume Replication Operations.
About Volumes
Volumes provide the storage allocation structure within the PS Series group.
To access storage in a PS Series group, you allocate portions of a storage pool to volumes. You can create a volume on a single group
member or one that spans multiple group members. You assign each volume a name, size, and a storage pool. The group
automatically load balances volume data across pool members.
Figure 5. PS Series Volumes depicts volumes in a PS Series group. Table 6. PS Series Volumes explains the callouts used in the
gure.
