Troubleshooting
Recommended Action
Verify that the READY indicator lights on the disk array
are ON.
Verify that fiber cables are correctly installed and firmly
connected.
Verify that the target IDs are properly configured.
The LUNs for each TID must start at 0 and continue
sequentially without skipping any numbers.
Verify that the TIDs/WWNs on each bus are unique.
Do not install two devices with the same ID on the same
bus.Recheck the buses for new devices.
Verify that LUSE devices are not intermixed with normal
LUNs on the same port.
Verify that the maximum number of LUSE devices per port
has not been exceeded.
Verify that the disk array host mode is set correctly.
If you power off the host without executing the shutdown
process, wait three minutes to allow the disk array's
internal timeout process to purge queued commands. If
the host restarts while the disk array is processing queued
commands, the host may not reboot successfully.
Verify that the disk array logical devices are correctly
formatted.
Verify that the volume capacity for OPEN-x volumes is
not greater than the maximum capacity allowed. See
Appendix B,Disk array supported emulations
Verify that the capacity of the volume group is not less
than the total capacity of the partitioned logical volume.
Verify that the host was restarted correctly.
Verify that the file system attributes are correct.
Reboot the host.
Contact HP.
Check the HBA and make sure it was installed
properly.Reboot the host.
Make sure there are no duplicate disk array TIDs and that
disk array TIDs do not conflict with any host TIDs.
