Post-Merge Tasks
After you merge two groups, perform the following tasks.
- Online all volumes that were previously in the source group.
- Update any SNMP clients to contact the group leader's (destination group's) management IP rather than the source group's, and the group leader's SNMP community name (rather than the source group's).
- For iSCSI groups, update initiators with the new discovery IP for these volumes and then reconnect.
- Re-arrange pool and volume assignments as needed. For example, merge the default source group into the default pool on the destination group.
-
If there was replication going to the source group, change it to
now go to the destination group.
- On any group (other than the destination group) that was previously replicating to the source group, create a partner to the destination group.
- Edit all schedules previously using the source group so that the destination group is used instead.
- Delete the source group as a partner.
-
If there was replication going from the source group, change it to
now come from the destination group.
- On any group (other than the destination group) that was previously being replicated from the source group, create a partner to the destination group.
- Promote all volume collections that were replicated from the source group (making the new group the owner).
-
Demote to the destination group.
This makes the destination group the new owner for these volume collections.
- On the destination group, all partners that were paused on the source group before the merge must be resumed.
-
Rezone.
If you had zoning set up, then re-zone due to changes to WWPNs for what was previously the source group.
