Problems expanding storage
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.
Cannot connect to a NAS share
The following sequence will cause problems when connecting to a NAS share.
1. Create an NFS share and mount it on a Linux box.
2. Delete the share on the HP StoreOnce Backup system without unmounting it from the Linux
box.
3. Recreate the share again with the same name.
In this scenario, the Linux client will assign a new set of inodes to the new share, but when trying
to access the old mount point it will use the previous set of inodes and will therefore not manage
to connect.
Reboot the host Linux system and the connection will work again.
Cannot access a storage shelf
Always power up with all storage shelves that have been configured attached. If a shelf is not
connected, none of the storage will start. In this case, power off, reconnect the storage and reboot.
Do not attempt to reconfigure the storage using the StoreOnce Management console.
If you disconnect a storage shelf, you must reconnect it to the same RAID controller to which it was
originally connected.
Contact HP Support if you have ongoing problems accessing storage shelves.
