Solving problems with multiple resynchronizations (Step 10)
During the upgrade process, both controllers perform a resynchronization simultaneously. This invokes a
fast restart of the controllers — bypassing execution of lengthy hardware diagnostics. This fast restart
allows the controllers to complete the resynchronization sequence before the host timeout period elapses
and the host becomes aware that the storage system is unavailable.
If an event occurs that causes a second resynchronization while the
fi
rmware upgrade resynchronization
is still in progress, the controller will terminate with a code of
0b 08 01 00
. The following events
cause the controller to resysnchronize automatically:
•
Initialization of the storage system
•
Setting debug
fl
ags through the command line interface or OCP
•
Occurrence of a disk group hardware problem on a Vraid1 virtual disk, or the return of a disk
during this condition
•
Bad Block Replacement (BBR) performed on a disk
•
Memory allocation failure or other errors
Every effort should be made to ensure none of these events occur during the upgrade process. If
controller termination occurs due to multiple resynchronizations, contact your HP-authorized service
representative for assistance.
