This issue has been solved. See solution.

Hi,

 

I have been facing a problem with tapes.

Most of the times required tapes are already available in the physical libraries,  At the same time, if i run the inventory on the master server, We loaded 104 media tapes but we can only see 1 tape.

This is a tape library issue or netbackup configuration? Please advise.

 

Environment

Windows Server 2008 R2 = Netbackup Master Server 7.5.0.5

Windows Server 2008 R2 = Netbackup Media Server 7.5.0.5

Tape Library =

 

 

Thanks,

John

Tape Library =

 

Need more info!

What kind of library?

What does the library hardware inventory show? 

Have you configured the storage unit in NetBackup?

What kind of library?

IBM TS 3500

What does the library hardware inventory show? 

The total slot of the tape library are 700 plus but when we do inventory we can only see 261 slot and 1 media tape but we already put 104 media tape on the tape library.

Have you configured the storage unit in NetBackup?

Yes, We done configuring the storage unit

In that case engage IBM support. NetBackup can only see what the hardware presents to it.

No configuration needed on the Netbackup?

Thank you very much.

Use robtest to see what the robot sees and presents to NBU:

s s

will show all slots.

As soon as robtest displays all slots that you expect to see, NBU inventory will work.

Hi Marianne,

Thanks for advise. i will let you know the result on tuesday or wednesday

The 3500 series libraries are good at hiding tapes from NBU.
Firstly, it is a library issue, I'm certain of that. If robtest s s only shows media in one slot, or, possibly only shows one slot in total, this will confirm my thoughts.

Possible causes are multiple, but I think most if not all of these will only happen if ALMS is turned on ?

(So if ALMS is not turned on, I'll have to think again ...)

The logical library has not been assigned any slots wthin the library config
Tapes have not been assigned to a logical library within the library config
Virtual I/O slots are enabled, and the tapes are hiding in there
Make sure the 'Queued Export' setting is set to 'hide'

Hopefully one or more or this will resolve the issue.

Martin

Hi Marriane,

Please see below the result of ROBTEST:

RobTest.jpg

We only see 261 slot but the total of the slot are 700 plus.

This is what the robot is presenting to NBU.

You need to check the robot config. Probably partitioned with only these slots assigned/configured?

Nothing can be done from NBU point of view to fix this.

If you are using ALMS, you have to add the number of slots you want to the logical library, if this is not done correctly, robtest will show fewer slots than there actually are.

If ALMS is NOT enabled then you should see all the slots, and there will only be 'one' library - if this does not show the correct number of slots I can only think it could be a license issue (I think the number of slots available is licensed on the 3584) or a library fault.

Possibly Your organisation has licensed only 261 slots out of 700 + slots and remaining 103 media might have been loaded in to other slots than these 261 licensed slots.

check the logical veiw of your tape library from the web-console and confirm this thing, if this is the case then shift the tapes to licensed slots only.

Hi,

We have to check if the ALMS is enable. But we checked last time the total slot from the control panel of the tape library and we can see from there the total slot and all the media tape that we insert.

The total slots is probably the total slots available in the library, not, the slots assigned to each partition.

That said, you haven't confirmed yet if ALMS is enabled - if I remember correctly if this is turned on, even if you only have one partition, youu have to then assign slots to it.

As mentioned before, if ALMS is turned off, and you have the correct license, I can only think it could be a library fault as with ALMS off, I think all the slots should be automatically assigned to the library.

The other possibility is that with ALMS turned on, you have a lot of slots configured as virtual I/O - these will not be available as regular slots as they are effectivly an extension of the CAP.

Can you get onto the web interface of the library - it is usually easier to see how it is configured and licensed from there

Usually this is down to either being partitioned, unlicensed or very often just a library fault and it is well worth checking for the latest robotic firmware and getting that applied (or get IBM in to do it)

If any changes have been made then re-run the device configuration wizard again to pick up the correct library information which includes the number of slots

This issue is solved.

The ALMS is ENABLE

We need to assign all the slot one by one. The reason we can only see the 261 slot because of the tape library license.

Thank you all for the quick reply.
