We have Auto Clean turned off in Networker (ver 7.2.1) for our L700 library. It caused us a variety of problems. Instead, cleaning is done manually using the GUI on the library. The cleaning tape is imported just prior to the cleaning, and exported it as soon as we are done.

We were also told by StorageTek that it is essential to have the correct bar code label on the cleaning tapes, otherwise the drives will not clean properly.

Hope that helps.

Starting sometime of Friday evening, one of the 4 LTO3 drives in our SL500 library decided it needed cleaning, so EBS 7.3.1 went on to grab a cleaning tape from an appropriate slot, then it finished the operation with a message "device cleaned notice: Jukebox `jb0' Device `/dev/rmt/3hbn' in jukebox `jb0' cleaned at" <date on Friday>. Ever since then, that drive has been displaying the same message every couple of minutes non-stop!
After poking around, I found the following:

In the Java Admin Console, the following shows up in 'Operations' tab under 'Monitoring', one after another:

Origin   Operation Data              Duration Progress Message
nsrmmgd  Clean device /dev/rmt/3hbn  30       retryable

In /nsr/logs/daemon.log, I see the same combination of lines repeat:

03/19/07 18:19:23 nsrd: [Jukebox `jb0', operation 2098]. Initiated operation `Clean device /dev/rmt/3hbn using cleaning slot 373'. 03/19/07 18:19:49 nsrlcpd #1: Jukebox error: Jukebox:jb0 access:/dev/scsi/changer/c2t2d0 failed:MOVE MEDIUM key:4 status:CHECK CONDITION No Additional Sense, Media Load or Eject Failed

03/19/07 18:19:53 nsrmmgd: Cannot update operation status resource (instance 2098).

What do you think is causing this, and how on earth can I stop it??! Drive /dev/rmt/3hbn still obeys commands such as "nsrjb -L -S 100 -f /dev/rmt/3hbn" so the drive seems to still work...
