How to connect Dell PV122T LTO2 to IBM p650 AIX5.2 and TSM5.2.3

Posted on 2005-04-08

We just got a Dell PowerVault 122T LTO-2 Autoloader (SCSI), and want to use it with our Tivoli Storage Manager server - IBM p650 running AIX 5.2 and TSM 5.2.3.

We can get the OS to see the drive through IBM's ATape driver, but can't get the OS to see the library.  Dell doesn't officially support AIX and does not provide AIX driver, but they to point to IBM's Tivoli support devices webpage, which listed Pv122T as supported on AIX since TSM 5.1.5.

We can see the tape drive as rmt3 in the OS, but cannot add it to TSM using SMIT or SMITTY.  We get error saying the device does not match the description.

We can't even get the library to show up on the OS lsdev list.

Any suggestion or advice?

Thank you in advance,

    Try a firmware update to the drive/library.  It may need to be FTP'd to the drive but this was my issue and it worked.

    Hi originalbiffmalibu,

    So you have the same setup?  That's great.  I'm begining to think we're the only one in the world crazy enough to hook a Dell autoloader to IBM p-Series running TSM.

    Can you tell me which version of firmware of drive and library you're using?  We can't find any firmware update on Dell's support site for our device, so we figured it came with the latest one.  Our is a 3YAD soomthing.  

    Or are you suggesting that we use an older firmware?  If so, where can I find it?  Also, how would we FTP firmware to the drive?  I thought we have to use the SCSI commands or firmware tape.

    Thanks a bunch,

    Sorry, I don't have the same drive, just a similar situation I resolved in this fashion.

    So, we are the only onesin the world crazy enough to try this setup.

    Anyway, can you tell me about your problem?  We connected the library up to the p650, and ran cfgmgr.  That got us the tape, but not the library.  It is as if we are connecting a single-tape drive to the server.  Nothing whatsoever on the library.  Was this your problem?

    Another thing is our library is always in SEQ (sequential mode), and we can't find a way to force it into random mode.  Did you run in to this as well?

    Thank you,

    We finally got the setup working.  Here is what we did.

    First we had to applied APAR IY44902 AIX 5.2 to our AIX server, which fixed the problem of not being able to add the Library part of the PV122T device using Tivoli Storage Manager driver via SMIT or SMITTY.  The bug was that we cannot add a device without any attribute.

    This allowed us to add the Library/Autoloader part of PV122T, which gave us lb0 device.

    So now in AIX using lsdev we can see rmt3 (the IBM LTO2 tape drive inside the PV122T) and lb0 (the Library/Autoloader part of PV122T).  The rm3 is using IBM ATape driver installed on AIX, while the lb0 is using TSM driver installed via SMITTY.

    After that, we had to go and delete the lb0's device special file in /dev, and ran cfgmgr again.  This created lb0 device using TSM driver.  I don't know why we had to do this, but it was IBM's suggestion, so we did.

    Anyway, so now we have AIX seeing the whole of PV122T.  From here, we just use TSM to add/define the drive and path for PV122T using the normal procudure.

    Just in case there are other people in the world crazy enough to do what we did.
