Solving Problems If The Storage System Does Not Come Back Online; Solving Problems With Multiple Resynchronizations - HP 6100 Software Manual

Solving problems if the storage system does not come back
online
The system software upgrade should take approximately 10 minutes to complete. If the storage system
does not come back within 10 minutes, check the following:
• Determine if the problem is with HP Command View EVA by performing the troubleshooting steps
in "HP Command View EVA
• Check any Remote Support Software messages.
1. Double click on the System Event Analyzer icon on the management server to run Remote
Support Software.
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 firmware 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 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.
