Cutover Statuses:

cutover_status='Y' 'COMPLETED'

cutover_status not in ('N','Y','X') and status='F' 'FAILED'

cutover_status='0' 'CUTOVER STARTED'

cutover_status='1' 'SERVICES SHUTDOWN COMPLETED'

cutover_status='3' 'DB CUTOVER COMPLETED'

cutover_status='D' 'FLIP SNAPSHOTS COMPLETED'

cutover_status='4' 'FS CUTOVER COMPLETED'

cutover_status='5' 'ADMIN STARTUP COMPLETED'  --> Issue occured here

cutover_status='6' 'SERVICES STARTUP COMPLETED'

cutover_status='N' 'NOT STARTED'

cutover_status='X' 'NOT APPLICABLE'

So Cutover Failed, But File system is already switched i.e patch edition (FS2) become run edition and run edition (FS1) become patch.

Run File System: FS2

Patch File System: FS1

Solution:

1. Source the Run edition Env file (FS2 is Run edition here)

2. Shutdown the application services and start only admin server.

3. Run the cutover again, this cutover will not bringdown and brought up any services and also will not flip filesystem again,  It will complete quickly.

adop phase=cutover mtrestart=no

4. Restart tha application services on all nodes.
