Symptom Possible causes Solution 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 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. 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. HP StorageWorks 149

Symptom
Possible causes
Solution
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.
