HP StoreOnce Backup - Manual (Page 166)

5. Look at the diagnostic message and scroll down to the logical drive section to locate the UUID
of the logical drive that is not configured.
NOTE: It is also possible to view the hardware tree from the StoreOnce GUI and expand
the tree to locate the storage enclosure that contains the alien LUN.
6. After identifying the logical unit that needs to be deleted, note its UUID because you will need
to specify this in the delete command.
7. Run the following StoreOnce CLI command to delete the LUN:
hardware delete storage <UUID>
The command will complete successfully if the LUN can be deleted i.e. it is not mounted.
8. After the delete command has completed rebuilding the storage system use the following
StoreOnce CLI commands to discover and add storage to the system:
hardware prepare storage
hardware add storage
This will configure both the storage in the appliance (base storage) and any attached expansion
shelves, if licenses are present on the appliance.
