Post-Merge Tasks

After you merge two groups, perform the following tasks.

  1. Online all volumes that were previously in the source group.
  2. 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).
  3. For iSCSI groups, update initiators with the new discovery IP for these volumes and then reconnect.
  4. Re-arrange pool and volume assignments as needed. For example, merge the default source group into the default pool on the destination group.
  5. If there was replication going to the source group, change it to now go to the destination group.
    1. On any group (other than the destination group) that was previously replicating to the source group, create a partner to the destination group.
    2. Edit all schedules previously using the source group so that the destination group is used instead.
    3. Delete the source group as a partner.
  6. If there was replication going from the source group, change it to now come from the destination group.
    1. On any group (other than the destination group) that was previously being replicated from the source group, create a partner to the destination group.
    2. Promote all volume collections that were replicated from the source group (making the new group the owner).
    3. Demote to the destination group.
      This makes the destination group the new owner for these volume collections.
    4. On the destination group, all partners that were paused on the source group before the merge must be resumed.
  7. Rezone.
    If you had zoning set up, then re-zone due to changes to WWPNs for what was previously the source group.
