Migrate Group Leader Functions to Backup Leader
Use the group command to migrate the group data and management services from the Group Leader (GL) array to the Backup Group Leader (BGL) array. Having the BGL take over the GL management role, you can maintain services even though the original GL is offline. At that point, you can take the former group leader offline or remove it from the group.
IMPORTANT: Manually moving the
GL array management role to the BGL array in the group is a support-assisted
procedure. Performing group leader migrations with encrypted volumes in any pool in
the group requires an outage window, because encryption passphrase reentry is
required. For more details about manual Group Leader migrations, refer to
KB-277.
Perform this task from the group leader array.
NOTE: It is a good practice
to migrate the GL management services to the BGL before performing a scheduled
outage.
