Perform a Manual Takeover of the Group Leader Array
- You must have set up a secondary management IP address that is associated with the backup group leader array.
- You must have an administration role associated with the backup group leader array.
- You cannot have Automatic Switchover (ASO) of Group Management Services enabled or the Witness installed.
- You cannot have a pool striped across two arrays in the group.
The takeover operation enables you to promote the backup group leader so that it becomes the group leader and takes over the management functions. You should only perform these steps if the group leader is not responsive.
NOTE: If the group
leader is responsive, but you want to migrate the group leader functions to the
backup group leader and promote it to group leader, use the group –migrate command to migrate the group leader
to the backup group leader. The takeover operation will fail if the group leader
is responsive.
- Remove synchronous replication.
- Set up synchronous replication.
- Perform a handover.
- (Optional) Migrate the group leader.
