Solution Possible causes Symptom
first level of logical device binding,
the FC HBA binds the FC WWPN and operating system path name
(\\.\Tape0) on a Windows host node 1. Disconnect the Windows node from
the SAN (label and unplug all FC
cables).

still shows these virtual tape drive
2. Delete all files and folders under the
"./system32/NtmsData" folder

At the second level, the Windows devices as being enabled and at the

Location.
(location of the system32 folder
varies between Windows versions).
Removable Storage Manager (RSM)
will bind the SCSI Bus Number, SCSI
3. In the Microsoft Computer
Management window, enable and
start the RSM.
Target ID, and SCSI LUN (SCSI layer
device) to an OS \\.\Tape# path
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.
See the Netbackup web site to
determine if the six character limit can Netbackup has a 6 character barcode
limit. Only 6 characters of the actual The VLS cartridge barcode numbers
displayed on Veritas Netbackup do
be changed. If the shortening of the VLS cartridge barcode numbers will
be displayed. not match the actual VLS cartridge
barcode numbers.
cartridge barcode numbers removes
characters from the barcode numbers,
making them no longer unique, the
barcode numbers cannot be used with
Netbackup. You must create new
cartridges with no more than six
character barcode numbers.
Manually create the device file for the
virtual library. See the Veritas
Netbackup manual. Netbackup on HP-UX cannot see
virtual devices on a VLS. Netbackup on HP-UX cannot build a
device file for a VLS library.
This is normal and will not cause
problems. Real autoloader libraries do not
support barcodes. Netbackup does not display the
cartridge barcodes for Autoloader
library emulations on the VLS.
To turn on barcode reader support in
Data Protector: By default, the barcode reader support
is turned off in Data Protector 5.1. HP StorageWorks Data Protector 5.1
does not display the VLS cartridge
barcodes.
