HP StorageWorks Data
Protector 5.1 does not
display the VLS cartridge
barcodes.
By default, the barcode reader
support is turned off in Data
Protector 5.1.
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.
VLS performance is
being reduced by test
unit readys (TURs) from
a Windows host(s) with
access to the VLS.
The Removable Storage Manager
or Removable Storage program on
a Windows host is submitting TURs
to the VLS.
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.
At reboot, there are
spurious critical FC
port failures reported
as noti fi cation alerts,
normally on every port.
Then, a little while
later, Info noti fi cation
alerts for each FC host
port are generated,
indicating the FC ports
are operating normally.
This is expected behavior and does
not indicate a problem.
None
After replacing drive 0
in a node, the system
will not boot.
A blank drive was installed in drive
bay 0.
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.
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.
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.
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.
