HP StorageWorks 300 - Virtual Library System EVA Gateway User Manual page 149

Symptom
HP StorageWorks Data
Protector 5.1 does not
display the VLS cartridge
barcodes.
VLS performance is
being reduced by test
unit readys (TURs) from
a Windows host(s) with
access to the VLS.
At reboot, there are
spurious critical FC
port failures reported
as notification alerts,
normally on every port.
Then, a little while
later, Info notification
alerts for each FC host
port are generated,
indicating the FC ports
are operating normally.
After replacing drive 0
in a node, the system
will not boot.
When oversubscription is
enabled and you create
enough cartridges in a
storage pool to put your
free storage capacity
below the threshold,
the pool may reach
critical status. If you then
disable oversubscription,
your storage pool will
remain in critical status
and will not return to
good status—even after
reboot.
Possible causes
By default, the barcode reader
support is turned off in Data
Protector 5.1.
The Removable Storage Manager
or Removable Storage program on
a Windows host is submitting TURs
to the VLS.
This is expected behavior and does
not indicate a problem.
A blank drive was installed in drive
bay 0.
When you disable oversubscription,
the system does not monitor the
storage pool's capacity, even to
check that it is no longer at a critical
level. The status will not change.
Solution
To turn on barcode reader support
in Data Protector:
1. Click Device & Media.
2. Right-click the VLS library name
and select Properties.
3. Click the Control tab.
4. Click the Barcode reader support
box to select it.
Stop the Removable Storage
Manager or Removable Storage
program, and set the startup type to
Disabled on the Windows host using
the Services utility located under
Control Panel > Administrative Tools.
None
If a blank drive is installed in drive
bay 0, the system will not boot. To
remedy this, switch the drive located
in bay 0 with the drive located in
bay 1.
Re-enable oversubscription, set the
alert threshold so that the storage
pool is within the capacity threshold,
then wait for the pool to return
to good (green) status. Disable
oversubscription and the storage
pool will maintain good status.
