• Retain the iSCSI target name of the original volume.
• Keep the ability to demote to the replica set. (Unless you are permanently promoting the replica set, make sure that you
keep this ability.)
7. Click Next to open the Promote Replica Set – iSCSI Access panel.
8. Specify the following information:
• Conditions that a computer must match to connect to the recovery volume. Type a CHAP user name, IP address, or iSCSI
initiator name.
• Recovery volume permission (either read-only or read-write).
• Whether to allow initiators with dierent iSCSI qualied names (IQNs) access to the recovery volume.
9. Click Next to open the Promote Replica Set – Summary dialog box.
10. Review the information. Click Finish, or click Back to make changes.
After the promote operation completes, the replica set disappears from the list of inbound replica sets, and the recovery volume
appears in the list of volumes.
Recovery Volume Options
After you promote an inbound replica set to a recovery volume:
• You can connect to the recovery volume.
• When the original volume on the primary group becomes available, go to the next step in the failover and failback process.
• To reverse the inbound replica set promotion and cancel the failover, demote the recovery volume to an inbound replica set:
a. Click Volumes.
b. Expand Volumes and then select the recovery volume name.
c. Click Demote to replica set.
• If the original volume becomes permanently unavailable, you can make the inbound replica set promotion permanent.
Recovery Volume Restrictions
To temporarily fail over a volume to the secondary group, you promote the volume’s inbound replica set to a recovery volume. Users
can connect to the recovery volume and resume accessing the volume data.
All volume operations apply to a recovery volume, with some exceptions:
• You cannot change:
– Volume size
– Volume name
– Public alias
– RAID preference
– Replication partner
– Thin-provisioning settings (applicable only to recovery template volumes and recovery thin clone volumes)
– Permission (applicable only to recovery template volumes)
• You cannot delete a recovery template volume if any of the following objects are attached:
– Recovery thin clone volumes
– Thin clone replica sets
– Permanently promoted thin clone replica sets
How to Handle a Failed Operation
To check the status of a Replicate to Partner operation and the Failback to Primary operation:
1. Open the Alarms panel and click the Failback Operations tab.
