Backup Software Errors
While the library product itself is supported by Hewlett-Packard, all software
products are supported by individual software vendors. (See Backup Software
Support on page 201.)
Your software applications may need to be reconfigured or, in some cases,
reinstalled after you have installed additional drives or slots into the library. In
addition, some backup software applications may require the purchase of
additional add-on components and/or licenses when increasing the number
of storage slots or drives.
Contact your software application provider for more information or if newly
installed storage slots and drives are not recognized by your backup software
application.
