Solving Problems With Multiple Resynchronizations - HP 6400/8400 Software Manual

• Check any WEBES messages.
1. Double click on the System Event Analyzer icon on the management server to run WEBES.
2. Click Full View under either System Log or the appropriate storage system in the left navigation
pane.
• Check the storage system event logs.
1. Run HP Command View EVA and log in.
2. Select the storage system whose logs you want to view.
3. Click View events to view the event logs that can be displayed.
If none of the above recommendations resolves the problem, contact your HP-authorized service
representative for help.

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.
