Troubleshooting
Recommended Action
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 the Device
Emulations Appendix.
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.
