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).
• The storage is installed in the wrong disk bay locations for this expansion set.
• There are any failed or predictive fail disks in either the existing or newly added storage.
• The SAS cabling to the disk enclosures is incorrect.
• There are any “foreign” LUNs already present on the attached storage.
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.
