wrong forum?

Hi asimafzal,

quite a terse problem description that you’re giving here :wink:

Mounting the tape is something that happens on the TSM server - which is (in your case) an AIX machine. This should be fairly independent from the client side of things, so I wonder why you’re asking in the SLES forums - is there some extra information that makes you believe that it has to do with the client and it’s OS (SLES11), and which you haven’t shared yet?

Regards,
Jens

Hi Jens,

Thanks for quick response.

Before coming to this forum first we open PMR with IBM and after analysis the logs they said “The outputs you provided, clearly show the problem is at OS level. Engage OS/HW libr vendor support to help you configure devices at OS level.*”

Actually we are facing issue on OS level while installing tape drives. Tapes mounted successfully but media changer is not mounting that why we are facing problem while taking lanfree backup through BA client.

Asim

please correct me if I’m wrong - but isn’t it that the tape drive / media changer is connected to your AIX server? That’d make it an AIX OS level problem.

If the lib/drive is connected to your SLES server, then we ought to be able to help you somehow, but of course would need some details (i.e. those outputs clearly showing it as an OS level problem :), but info on the tape and lib manufacturer(s), connection type and host adapter, too) to help to diagnose this.

Regards,
Jens

hi jens,
please note that when give the command cat /proc/scsi/IBM* the output shows the two RMT’s Drive but medium Changer is not available their why ? is there device driver is not loaded properly or OS(Suse linux 11 x86_64) is not supporting that device driver what is that reason. Our machine storage agent(Suse linux 11 x86_64 ) is properly working and connected with TSM server v6.2.2.0 (AIX 6.1 OS) . Please check the output of command cat /proc/scsi/IBM

now I see - at first I didn’t catch that there’s a storage agent running on the SLES machine. You’re in the right forum after all :slight_smile:

To assist further debugging, I recommend to provide answers to the following questions:

  • Are there some files /dev/IBMchanger* and/or /dev/lin_tape//?

  • What does “lsscsi -lg” report?

  • What messages appear in syslog (i.e. /var/log/messages) when you power-cycle the library?

  • Have you run the kernel driver with debugging enabled (option “lin_tape_debug=1”) and what did it report?

That will give us an idea of what’s happening at the lower layers of SCSI and how the SLES system reacts to these events.

Regards,
Jens

well, the changer isn’t even recognized by the SCSI sub-system - no wonder nothing else can be seen of it within SLES…

How have you set it up SCSI-wise? Is it connected to the same bus SCSI as the tape drives? Does it have a unique SCSI ID?

[QUOTE=asimafzal;18096] - What messages appear in syslog (i.e. /var/log/messages) when you power-cycle the library?
AskariBar:/dev # grep -i error /var/log/messages[/QUOTE]
I would have preferred to see everything related to the SCSI system, including scan results, driver messages, udev etc. - not just some error messages. And please limit it to start (about) at the moment you power on the library and have it end a few moments after the SCSI stuff settled (should probably be not more than 10 seconds after the initial SCSI activation of either the changer or the drives).

When quoting output, it is much more readable if you wrap it in “[ CODE ]” - “[ / CODE ]” (without these quotes nor blanks) tags. When using the Advanced forum editor, simply mark that part of your message and click the “#” button in the editor tool bar.

[QUOTE=asimafzal;18096]- Have you run the kernel driver with debugging enabled (option “lin_tape_debug=1”) and what did it report?
do nothing
AskariBar:/dev # lin_tape_debug=1[/QUOTE]
Please have a look at IBM’s lin_tape documentation, it describes how to actually configure the driver and the daemon and how to enable driver options. But I have a feeling that the error cause lies within the SCSI configuration of your library, so you might reserve that debugging step for later.

With regards,
Jens

I’m sorry but this is outside of my current experience.

Maybe someone else with SCSI multipath knowledge can jump in here?

Hi,
Maybe little bit late to answer your question now on this.
I had the same problem with SLES 11 SP3 and lin_tape 2.5 with a IBM TS3500 and LTO-5 and LTO-6 with Dual FC Path.

The answer was following add following lines to /etc/modprobe.conf.local

options lin_tape alternate_pathing=1
options lin_tape tape_reserve_type=persistent

And then reboot the drives in the TS3500 and also restart the lin_tape driver.

lin_taped stop

rmmod lin_tape

depmod

service lin_tape

Now it’s working.

Cheers
Christian

[QUOTE=jmozdzen;18092]Hi asimafzal,

now I see - at first I didn’t catch that there’s a storage agent running on the SLES machine. You’re in the right forum after all :slight_smile:

To assist further debugging, I recommend to provide answers to the following questions:

  • Are there some files /dev/IBMchanger* and/or /dev/lin_tape//?

  • What does “lsscsi -lg” report?

  • What messages appear in syslog (i.e. /var/log/messages) when you power-cycle the library?

  • Have you run the kernel driver with debugging enabled (option “lin_tape_debug=1”) and what did it report?

That will give us an idea of what’s happening at the lower layers of SCSI and how the SLES system reacts to these events.
