Troubleshooting - HP Surestore Disk Array 12h - And FC60 Configuration Manual

Table 1. Error Conditions
Error Condition
The logical devices are not
recognized by the system.
The SGI system does not
reboot properly after hard
shutdown.
The SGI system hangs.
If the system has an error condition, see Table 1 for recommended actions. If you are
unable to resolve an error condition, ask your HP service representative for assistance.
Recommended Action
Be sure the READY indicator lights on the disk array are ON.
Be sure the SCSI cables are correctly installed and firmly connected.
Be sure the SCSI terminators are properly connected.
Be sure the SCSI TIDs are properly configured. The LUNs for each SCSI TID must
start at 0 and continue sequentially without skipping any numbers.
Be sure the SCSI IDs on each SCSI bus are unique. Do not connect two devices with
the same SCSI ID on the same SCSI bus.
If the system is powered off without executing the shutdown process, wait three
minutes before restarting the system. This allows the disk array's internal time-out
process to purge all queued commands so that the disk array is available (not busy)
during system startup. If the system is restarted too soon, the disk array will continue
trying to process the queued commands, and the system will not reboot successfully.
Make sure that the TIDs are set 0 through 6 and 8 through 15 and that TID 7 has
been reserved for the fast-wide SCSI controller card.
