I Cannot Create A Device; I Cannot See A Newly Created Device; I Cannot See Additional Slots From The Backup Application; A Deleted Device Keeps Reappearing - HP StorageWorks D2D User Manual

• If it is accessible, there is a problem with the backup application. Certain backup applications
require you to use their own drivers for both the tape device and medium changer. If this is
the case, you must install the backup application drivers manually after the Installation wizard
has completed.
• Make sure that the iSCSI initiator is connected to the devices and log on to them, if they are
not. See "Targets
• If it is not accessible, rerun Discovery.

I cannot create a device

The HP D2D Backup System supports a maximum of six devices.

I cannot see a newly created device

When you create a new device on the HP D2D Backup System, the host will not be able to see the device
until you connect manually to it using the iSCSI Initiator. See
for more information.
If you still cannot see the device, check Device Manager to make sure it is visible from the host.

I cannot see additional slots from the backup application

When you create additional slots for an autoloader on the HP D2D Backup System, you may need to
restart services on the backup application so that it can see the new slots.

A deleted device keeps reappearing

When you create a device with the Installation wizard it is always configured as a Persistent Target
on the host. This means that the connection will automatically be restarted each time the host logs
on to the HP D2D Backup System. To delete the connection, use the iSCSI Initiator as described in
"Persistent Targets

If backup is slow

Are you connecting to a 10/100Base-T port? 100 Base-T will limit performance; 10 Base-T will severely
limit performance.
Check that other network traffic is not too heavy. Congested networks will slow performance, even
on Gigabit.
Check the backup application. If you are backing up a client of a backup server, the bottleneck may be
in the backup server.
Ensure that the host being backed up is not in use at the time of backup.

Cartridge troubleshooting

• Cannot resize cartridges
• My tape drive has run out of space
• My physical tape drive has a smaller capacity than the cartridge size on the HP D2D Backup
System

I cannot resize cartridges

The only time you can resize cartridges is when you first create an autoloader or add slots and they are
blank. Once the cartridges are made available to the backup application, it formats them ready for use
and they are no longer blank, even if you have not yet written data to them. Similarly, the erase function
on most backup applications does not return the cartridge to a blank state.
