HP MSL-2024 Tape Library. How?

Comrades, I need help with the tape library. I’ve not worked with this for a thousand years, and I forgot everything. From what I remember, there is nothing close to the reality that I see.
And so the gist:
Given: 

  1. Server with Windows 2012 R2
  2. HP MSL-2024 Tape Library

 Library with server connected via SAS via HP Smart Array P212 controller

Backup software - Backup Exec 2014 (and installed more recent versions)
In the device manager, it is defined as follows:

 In Backup Exec:

The first thing that annoys is that only 2 cassettes of 781 GB are displayed in the cells of the library. (although everything is clogged to the eyeballs - 24 pcs.)
2nd — with backup, in theory, it should be like this: the cassette is filled, the next one is served, etc. Well, I remember how it was when I worked with them.
Now, 2 cassettes are clogged and there is a request for fresh ones. But it should not be the same. This is not a streamer ....

The driver seems to be all fresh. Controller supported (by specification). The only thing is that the library firmware is old, but there is no way to update it, since in order to download it,HP service contract required. And he, after the prescription of years and the change of several generations of admins, is "ambitious". But something I don’t think can affect the work ...

I’ve been fighting this week already, and I can’t do anything. Can anyone have any thoughts? You can even crazy

Maybe the lib is partitioned?

Hope this helps!

Re: HP MSL-2024 Tape Library. How?

You can devide the library into logical (sub) librarires.

But it is not the case here.

The slots are "reserved", most likely "locked" by the backup application, hence you see only 2 "normal" slots.


Hope this helps!

Torsten.

Re: HP MSL-2024 Tape Library. How?

From user guide:

 

Setting the number of reserved slots (Configuration > Set Reserved Slot Count)


You can access reserved slots from the RMI and the OCP, but the reserved slots are invisible to the host and
backup software. For example, you might keep a cleaning cartridge in a reserved slot if your backup software
does not manage the cleaning process.
You can reserve up to 22 slots.
Prerequisites
Access to this feature requires the administrator password.
Procedure
1.
From the Home screen, press Previous or Next until the screen displays Configuration. Press Enter to
select.
2. Press Previous or Next until the screen displays Set Reserved Slot Count. Press Enter to select.
3. Enter the administrator password if prompted.
4. Press Previous or Next to scroll through the display until the desired number of slots is displayed, then
press
Enter


Hope this helps!
Regards
Torsten.

I removed the status reserved:

But this did not correct the situation. In BackupExec, I still see only two cassettes.

You probably need to refresh this information now (from the backup software point of view).

Maybe you need to create new pools.


Hope this helps!

I’ll try it now, but I’m not sure of a positive result (It seems that at the initial stage, when I started to deal with this, I already took these steps ...

Re: HP MSL-2024 Tape Library. How?

In the beginning the lib reported only 2 slots to the host, now it reports a lot more slots ... check also with LTT.


Hope this helps!

@Torsten. 

I don’t know if your advice helped or not. But he was useful and I will mark his decision.
And for the story, what I did, in addition to the tips that were given to me above:
1) Reinstalled OS
2) Installed all the drivers for the tape library.
3) Put all available OS + driver updates with windows update.
4) After that, he alternately slept out the tape library shops, wiped the side with the barcode, and checked how the cassettes exit the cells.
5) Rebooted, installed LTT - and there I saw all the cells.
6) Installed BackupExec - and there I also saw all the cassettes.
