Slow Backups - Certance LTO-2 Online User's Manual

Troubleshooting Guide
If the tape did not eject and the LEDs show "POST Failure," "Hardware or Firmware Error," or "Man-
ual Intervention Required," the drive may be bad. Contact Technical Support.
If you have a problem with inserting a cleaning cassette and receive the message:
2.
"The last cleaning cartridge used in the tape drive has worn
out:
It means the cleaning cartridge is used up. Purchase a new cartridge to perform any more cleaning
cycles. Normal operation of the drive is not affected. The drive will continue to automatically eject
the expired cleaning cartridge.
If you insert a cleaning tape that is not expired but the tape is being ejected by the tape drive
3.
without performing the cleaning, you may see the message:
"The last cleaning cartridge used in the tape drive was an
invalid type:
1. Do not use this cleaning cartridge in this drive.
2. Wait for the current operation to finish.
3. Then use a valid cleaning cartridge."
This message means the tape drive does not recognize the cleaning tape as being of a valid type.
You may have purchased a cleaning tape that is not supported by the tape drive. Purchase a sup-
ported cleaning tape.
If the tape drive issues a message to backup software to instruct you to clean the tape drive,
4.
you may see the message:
"The tape drive needs cleaning:
1. If the operation has stopped, eject the tape and clean the
drive.
2. If the operation has not stopped, wait for it to finish and
then clean the drive.
Check the tape drive users manual for device specific cleaning
instructions."
This message means you should use a supported cleaning tape.

Slow Backups

There are many factors that can make backups appear to be "slow." To achieve the highest possible
transfer rate, the LTO-2 half-height tape drive MUST be attached to a Low Voltage Differential ( LVD )
SCSI controller capable of a minimum of 80 MB/s and MUST not share the same SCSI bus as
another active SCSI device such as hard drives.
Is the tape drive attached to an LVD SCSI controller? This can be determined by viewing the
1.
boot process of the system and looking to see what controller the tape drive is attached to.
There may be boot log files that can be examined to determine what SCSI controller the tape
drive is attached to.
1. Discard the worn out cleaning cartridge.
2. Wait for the current operation to finish.
3.
Then use a new cleaning cartridge."
