name. Only tape drives are subject to
this second binding level.
NOTE: If you have built and
connected Windows nodes before
installing the VLS system, the Windows
tape device paths can break, change,
or disappear when RSM is run.
(Windows runs RSM by default.)
When RSM initially discovers any
removable storage device, such as a
tape drive, it will make an entry in
NtmsData database. Once a tape
drive is listed in this NtmsData
database, the Windows OS can
potentially either break the second
level OS path name bind or re-bind it
to a different OS path name, even
with RSM in a "Disabled" state.
4. Bring up the Removable Storage
utility in the Microsoft Computer
Management window.
5. Verify there are no Tape or Library
devices listed (other than the direct
attached devices such as the
CD-ROM drive).
6. Stop and Disable the RSM service
in the Microsoft Computer
Management window.
7. Reconnect the Windows node to the
SAN (plug all FC cables back in to
the original HBA Ports).
8. Repeat this process on all Windows
backup server nodes.

Manually create the device file for the

Netbackup manual.
Netbackup on HP-UX cannot see
virtual devices on a VLS.
Netbackup on HP-UX cannot build a

This is normal and will not cause
problems.
Real autoloader libraries do not

Netbackup does not display the
