You do not really have to walk to the jukebox...
You can use the sjirdtag command that will talk directly to the jukebox
and provide you the REAL status of the drives/slots.

Thanks - Unfortunately this only ends in the drive being put into service mode, so this doesn't seem like to correct way for things to work. In addition, I don't really believe that the tape has been unmounted. I'll have to run over to the library to check this out, but the last time this happened, the drive was *not* unmounted, and it was completely unresponsive. It couldn't even be unmounted from the front panel of the jukebox. I needed to power-cycle the jukebox to resolve this issue.

In high active datazone, it can happen that nsrd forget to update jukebox map (fields loaded barcode, loaded volume and loaded slot) while unloading volumes. Most of the time, it's done when multiple nsrjb are running concurrently, the changes done by the first nsrjb not being commited yet into config files and in memory jukebox maps.

Jukebox map not being updated, networker still think a tape to be loaded in the device and try to unload it. But reality is such no tape to be loaded.

Result is nsrmmd fails with an opening I/O error. Then nsrjb tries, during 20 minutes to unload the tape. After that, it reports an error and mark the slot as unloaded. (In some time, you can also lose the inventory of the slot containing the ghost volume before second nsrjb).

I never found a way to reduce these 20 minutes to something more acceptable but am working with it. It has nothing to do with load/unload sleep, these values just being the time networker waits between jukebox PUT to device or UNLOAD from device before opening the OS driver (/dev/rmt/...., \\.\tapex)

HTH,

Th

I have a similar problem on an ATL-P7000 tape library.

However I *am*

still on a Sun server platform.  Does anyone know what the unload

sleep

for that type of library should be?  Mine is set at "5".

I get these types of errors almost every weekend:

02/05/05 06:38:22 nsrd: /dev/rmt/45cbn Eject operation in progress
02/05/05 06:42:33 nsrd: media warning: /dev/rmt/45cbn opening: I/O

error

02/05/05 06:42:53 nsrd: media info: unload error for jukebox

`ATL-P7000'

detected.  Retrying
02/05/05 06:42:53 nsrd: media info: unload retry for jukebox
`ATL-P7000': sleeping 30 seconds
02/05/05 06:43:38 nsrd: media info: unload retry for jukebox

`ATL-P7000'

failed - will retry again.
02/05/05 06:43:38 nsrd: media info: unload retry for jukebox
`ATL-P7000': sleeping 30 seconds
<snip>

This continues until the drive goes into service mode.  Is this

possibly

related to the unload sleep?  Or is there something more wrong here?

Thanks,
Brian
