HP StoreOnce Backup - Manual (Page 152)

5. The information message advising you that the HP StoreOnce Backup System is optimizing is
normal and does not require you to take any action. The status will become OK as soon
optimization completes, but it may take some time. If you look at the Status—Storage page,
the same message is displayed but all relevant storage pool information is available.

Creating cartridges (Virtual Tape Devices only)
All cartridges and data were lost when the disks failed. Before you can use the HP StoreOnce
Backup System you must create new cartridges. Use the Create all button to create a blank cartridge
of the size/emulation type selected when the library was first configured in all empty slots.
