Solving problems with multiple resynchronizations During the upgrade process, both controllers perform a resynchronization simultaneously.

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 upgrade resynchronization is still in progress, the controller will terminate with a code of 0b 08 01 00.

If controller termination occurs due to multiple resynchronizations, contact your HP-authorized service representative for assistance.

Solving problems with multiple resynchronizations
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 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 flags through the command line interface or WOCP
•
Disk group hardware problem on a Vraid1 virtual disk, or attempted re-connection of a disk when
there is a disk group hardware problem
•
Bad Block Replacement (BBR) performed on a disk
•
Memory allocation failure or other errors
Every effort should be made to ensure that 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.
