• If it is accessible, there is a problem with the backup application. Certain backup applications

requireyoutousetheirowndriversforboththetapedeviceandmediumchanger. Ifthisis

the case, you must install the backup application drivers m anually after the Installation wiza rd

has c ompleted.

• Make sure that the i SCSI initiator is connected to the devices and log on to them, if they are

not. See “Targets tab”onpage49

• 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

WhenyoucreateanewdeviceontheHPD2DBackupSystem,thehostwillnotbeabletoseethedevice

until you connect manually to it using the iSCSI Initiator. See “Advanced installation” on page 45

for more information.

If you still cannot see the device, check Device M anag er to make sure it is visible from the host.

I cannot see additional slots from the backup application

When you cre

ate ad d itional 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 tab” on page 50.

If backup is slow

Are you co

nnecting to a 1 0/1 0 0B a se-T port? 100 Base-T will limit performance; 10 B ase-T will severely

limit pe

rformance.

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 ba

ckup 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

Theonlytimeyoucanresizecartridgesiswhenyouﬁrst create an autoloader or add slots and they are

blank. O nce the cartridges a re made available to the backup application, it formats them ready for use

and they are no long er 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.
