lin_tape on RHEL 5.5

[nulled06]

Hello.
Guys, i need help with my problem.
I have a rhel 5.5 server with lin tape and tsm server. Library TS3100.
After install lin_tape i dont have some device on /dev.

[root@tsm ~]# ll /dev/IBM*
crw------- 1 root root 251,    0 Oct  4 11:32 /dev/IBMtape0
crw------- 1 root root 251, 1024 Oct  4 11:32 /dev/IBMtape0n

But if i run lsscsi i have:

[0:0:0:0]    disk    ServeRA  R1-TSM           V1.0  /dev/sda
[0:1:0:0]    disk    IBM-ESXS VPBA300C3ETS11 N A496  -

[3:0:0:1]    disk    IBM      1814      FAStT  2916  /dev/sdb
[4:0:0:0]    tape    IBM      ULT3580-TD4      8192  -
[4:0:0:1]    mediumx          3573-TL          6.70  -

As i understand it, mediumx is IBMchanger device.
From this i understand, lin_tape not detect device

cat /proc/scsi/IBM*


lin_tape version: 2.9.1
lin_tape major number: 251
Attached Changer Devices:
Number  model       SN                HBA             SCSI            FO Path

In log Lin_tape i have

lin_taped  Thu Oct  2 18:24:34 2014
   Detects 1 IBM tape drives.
lin_taped  Thu Oct  2 18:24:34 2014
   Failed to detect any changer devices.

So.. i spend 2 week to resolve this problen and now i despair.
Guys you my last chance.

P.S sorry for my bad English

Hello.

I think the problem is that the changer is not reporting as an IBM device, which is probably why lin_tape is not detecting it.

Hmmm, but how i can add ibm label to him?

i don't think that's the right question. why isn't the changer identifying itself as an IBM changer?

 

[nulled06]

Yes, you right. But i really dont know why it dont response like ibm hardware.

Me either. Is it real IBM hardware? If so, it sounds like you should have hardware support take a look. If it's a VTL - maybe you need help from that vendor. Or maybe you can try emulating something else.

 

[nulled06]

Ye, its real ibm hardware. Changer work with mtx, maybe i can configure TSM with out lin_tape? Any one have this experience ?

You shouldn't do this. It should work with lin_tape.

I've created an identical library with VTL software on RHEL 6.5 and it works fine.

Are you using the latest lin_tape driver? Is the drive/library firmware up to date? Have you rebooted the system and library?

I can try with RHEL 5.5 later, but that's awefully old, so you might consider getting to 6.X someplace.

 

[nulled06]

Yes, lin tape is update to last version. I cant upgrade this server (many other resource). Yes, i try reboot library, its not work. Unfortunately i cant upgrade firmware. My company not save doc about buying library. It was on 2011. And ibm support dont wont help me. Library work until day x. After system not see changer, but mtx use it fine.

Have you gotten to IBMtape/lin_tape driver support yet? You need to convince the hardware support that you need to get to that team, but to get to them you have to tell the CE's that you need device driver support.

Sorry for necropost, but i solve this problem.
If any one have this problem you need go to library over telnet, authorize with you login and use svd command. Syntax you can see on help page in telnet console.
