The Computer No Longer Recognizes The Drive In A Tape Array; Problems With Cleaning - HP LTO Ultrium Technical Reference Manual

The computer no longer recognizes the drive in a tape array

Possible Cause
You powered up the drive or
added it to the tape array
after the host system was
turned on.
The drive is not inserted cor-
rectly.
There is a fault with the host
system.

Problems with cleaning

Use the following table to resolve cleaning problems:
Problem
Recurring cleaning message.
The cleaning cartridge is ejec-
ted immediately after loading.
If the drive is installed in a library:
Problem
A brand new data cartridge is
used, and the library operator
panel indicates that cleaning
is required.
Potential Solution
Most modern host bus adapters/host systems will only locate and display at-
tached devices when the system is booting up. Try rebooting your host system
after the tape array is powered up.
Check the drive is properly inserted into the tape array so that it mates with
the connections at the rear of the enclosure. The extraction lever should be
pushed in, locking the drive in position.
1. Make sure that the system is configured to recognize the device.
2. Ensure that the correct driver for the tape drive is installed. Look at the
host adapter documentation and backup software documentation for
further advice.
Solution
Clean the drive with an LTO Universal Cleaning Cartridge as instructed in
the tape library documentation. If the message reappears, replace the cleaning
cartridge with a new one.
If the message reappears when a particular data cartridge is used, verify that
the data cartridge is readable by clearing the message and reading the tape
again.
If the data cartridge can be read, back up the data to another cartridge and
then discard the damaged one.
Make sure that you are using an approved LTO Ultrium Universal cleaning
cartridge and that the cleaning cartridge is not expired.
Solution
Clean the outside of the data cartridge with a barely damp, clean, lint-free
cloth. Clean the drive as instructed by your tape library documentation.
If the operator panel indicates cleaning is required within a short period of
time, replace the data cartridge.
