Troubleshooting
Discover storage fails
The hardware discover storage command will fail if:
• A previous discover storage command is already running.
• There is no storage to be added.
• There are insufficient expansion licenses applied to allow the entire expansion to complete
(in this case, no expansion will take place until sufficient licenses are present for all added
storage).
• There are any “foreign” LUNs already present on the attached storage. In which case the
foreign LUNs will need to be deleted with the command hardware delete storage. See
the Maintenance and service guide for more details.
• There are any failed or predictive fail disks in either the existing or newly added storage.
• The storage is connected to an incorrect RAID controller or is daisy-chained from the wrong
expansion enclosure.
Add storage fails
The hardware add storage command will fail if:
• There is an outstanding discover or add command in progress.
• Any of the error conditions described above for the hardware discover storage
command have not been rectified.
