Deleting Replication Sets; Reversing Roles - Sun Microsystems StorageTek 6140 Administration Manual

Deleting Replication Sets

When you delete a replication set, the primary volume stops replicating data to the
secondary volume. The association between the primary and secondary volumes is
removed, and both revert to conventional volumes. The data stored on the volumes
is not affected, and the volumes can remain mapped. You can delete multiple
replication sets simultaneously.
To remove the replication relationship between volumes:
1. Click Sun StorageTek Configuration Service.
The Array Summary page is displayed.
2. Click the name of the array on which either volume in the replication set resides.
The navigation pane and the Volume Summary page are displayed.
3. In the navigation pane, choose Logical Storage > Replication Sets.
The Replication Set Summary page is displayed.
4. Select the replication set that you want to delete, and click Delete.
A confirmation message is displayed.
5. Click OK.
The replication set is deleted.

Reversing Roles

You can reverse the roles of the primary and secondary volumes in a replication set
in the event of a failure of the primary volume. The secondary volume assumes the
role of the primary volume so that the application software now accesses the
secondary volume directly while the primary volume failure is corrected.
You can perform the role reversal from either volume in the replication set. For
example, when you promote the secondary volume to a primary role, the existing
primary volume is automatically demoted to a secondary role (unless the system
cannot communicate with the existing primary volume).
Note: If you change the role of a volume in a replication set that is a member of the
consistency group, the replication set will become a member of the consistency
group on the array that hosts the newly promoted primary volume.
To reverse the role of volumes within a replication set:
1. Click Sun StorageTek Configuration Service.
The Array Summary page is displayed.
