Abort System Lock
The Abort System Lock command can be used to stop the system lock. It is
available as soon as a lock for update is initiated.
Clicking Abort System Lock returns the redundant chassis status to Primary with
Disqualified Secondary. Clicking Abort System Lock also results in the system
update stopping and the program in the secondary controller being cleared. If you
click Abort System Lock, you need to download the program to the secondary
controller before re-attempting a Lock for Update.
