Problem

Solution

Tape stuck in drive.

1.

Power cycle the autoloader, allow it to complete

initialization, which in rare cases can take as

long as 10 minutes, and then retry unloading the

tape using the autoloader operator control panel.

2.

Allow the tape drive to complete all operations.

This may take as long as ten minutes if you

reset or cycle power on the autoloader while

the cartridge is positioned at the physical end

of the media.

3.

Make sure that the backup software is not

reserving the slot or preventing the tape drive

from ejecting the cartridge. The backup software

needs to cancel the reservation and any hold it

has on the tape drive. Temporarily disconnecting

the autoloader from the host server and power

cycling eliminates the host and its software as

a problem source.

4.

Contact your service representative.

Media
Cleaning or data cartridge incompatible with drive.

Make sure you are using data and cleaning

cartridges that are compatible with the

drive and model of your autoloader (see

Backward read compatibility

” on page 32). The

autoloader automatically unloads incompatible

cartridges, the Media Attention LED flashes, and an

exclamation point (!) displays in the inventory display

for the indicated slot number. You will need to export

the media in order to clear the state. Media that is

damaged or put in a very dirty drive may also be

marked as incompatible.

Cannot write to or read from tape.

Make sure that the cartridge is write enabled

(move the write-protect switch to the enabled

position).

Make sure you have the appropriate data

cartridge for your autoloader model. HP

recommends DAT 72 cartridges for DAT 72X10

1U autoloaders.

Make sure that the cartridge has not been exposed

to harsh environmental or electrical conditions

and is not physically damaged in any way.

Many backup applications do not read or write

to cartridges that were created using a different

backup application. In this case, you may have to

perform an erase, format, or label operation on

the cartridge.

Make sure you understand any data protection

or overwrite protection schemes that your backup

application may be using, which could prevent

you from writing to a given cartridge.

Clean the tape drive. See

Cleaning the tape drive

” on page 42.

Retry the operation with a different, known good

cartridge.
