can't detect cleaning tapes in the None volume pools

HI,

I have a problem when i inventory the 'None' volume pools, i don't see my cleaning tapes. Below the result of vmrule ;

# vmrule -listall
===================================================================
rule number:  0
barcode tag:  CLN
media type:   HC3_CLN
pool name:    None
cleanings:    25
description:  ---
================================================================================
The name of the cleaning tapes is : CLN007CU et CLN008CU. In the library (scalar i500), i see my cleaning tapes with "cleaning" legend, but on my sever netbackup, i haven't a result with the command "/netbackup/openv/volmgr/bin/vmquery -a | grep -i cln".

Any ideas please ?

    I suspect the library is set to clean, so is hiding the cleaning tapes from NBU. If you run robtest, then the command s s Look through the output, are the cleaning tape barcodes visible ? If they not, which is what I am expectting you need to turn the cleaning feature off on the library, the library will then allow NBU to access the tapes, and they will be vsible in (robtest) s s Running a NBU inventory should then resolve the issue.

    you're right i don't have cleaning tape barcodes visible in the output of robtest.

    To turn off the cleaning feature on the library, in your opinion, should i select "none" in the below screen shot of yhe library ? at the moment we have 2 cleaning tapes.

     

    Setup Cleaning Slot Configuration
    Choose the number of designated cleaning slots for the library:

    Current Settings: New Settings:
    2 slots None (Autoclean will not be available)
      1 slot
      2 slots

    I'm not familiar with that library, but as a guess, yep ...

    Some libraries have dedicated slots for cleaning tapes that can't be changed, if you still don't see the tapes in robtest you'll need to move them to 'normal' slots.

    Yes, so would I .... There is not really any need for NBU to hande the cleaning. The drives should still only be cleand when they send out the tape alert, and it really comes down to who triggers the load of the cleaning tape - the library itself or NBU. The advantage of letting the library do it is simply that it's easier to set up - no need to have extra media id / barcode rules. When I used to run environments (IBM 3584 libraries mainly) we used to just load then with 10 or so cleaning tapes and let the library handle it, removing and adding new tapes as required.

    Hi,

    Even if i configured Cleaning Slot at none (Autoclean will not be available on scalar i500), i can't see my cleaning tapes in the output of robtest command.

    also, the slots for cleaning slots are dedicated, and can't be changed on this library.

    Any other ides please ?

    The cleaning slots in the robot are meant for cleaning by the robot. NBU (or any other backup application) does not have access to these special slots and cannot see or use these tapes.

    If you want NBU to do drive cleaning, you need to take these tapes out of the special cleaning slots and put them into the 'normal' slots.
    NBU will now be able to see these tapes and add them as cleaning tapes.
