IBM TSM : tsm server doesn' detect my tape drive

Hello expert,

I am having an issue with my tape drive.

We have a tsm server 7.0 (windows 2008 entreprise) which is  attached to a scsi tape library (overland neo 200).
 .
A few days ago, we had to shut down the server and the tape drive for a maintenance operation (I have also disconnected the scsi cable for a few minutes and then reconnect it).

Since the reboot, tsm doesnt' recognize the tape library.

tsmdlst (device list utility)
So, I have reinstalled the drivers from the neo overland storage, I have also installed IBM Tape Diagnotic tool (itdt), but the server still cannot scan the tape library.

I have rebooted the server a couple of time and I  also double check the scsi cable, it seems ok. What can I do?

"TSM Device Driver:  TSMScsi - Not Running" maybe the problem?

When you say you disconnected the SCSI cable, where was this at the server end or the library end? Did you plug it back into the same place?

Please describe what your SCSI cable looks like? Is it a SAS cable or a Fibre Channel cable?
Is the library directly connected or via a switch?

Yes "TSM Device Driver:  TSMScsi - Not Running"  can be the problem but I haven't found how to fix it.

To answer your question, I have plugged back the cable in the same place (the library is directly connected to the server).
I have double checked different time.

Those tiny pins can be a problem any time you plug a cable in.  Take a magnifying glass and carefully inspect the pins for alignment.   Swap in a different cable, see if it works then.  It's also possible that the flexing of the cable loosened a contact internally.

Ah parallel SCSI, that takes me back! You might have to shut every thing down (ie power off everything) turn on the tape drive/library and then power on the server

hello @Gerald Connolly. unfortunately I did this before, but it didn't work.

Gerald is right -- did you wait until the tape library was fully online before you powered on the server?  WIth SCSI devices, allowing the peripherals time to completely boot was often important -- hot plug was just a dream.

Hi Cismoney,
the problem is NOT "TSM Device driver" as reported by tsmdlst.exe: "TSM Device driver" is usually used for non IBM autoloaders, while the NEO 200 is really an IBM machine Dell-rebranded.
You need to follow instructions from the following link:
http://www-01.ibm.com/support/docview.wss?uid=swg21238577

You need to make sure that your windows server sees both tape and autochanger from device manager: only after that you will have to check on TSM, by issuing "q drive" and "q path".

I never worked with NEO 200 but I know very well IBM TS3100/TS3200: if the procedure is the same, you need to install windows drivers by running the file "install_exclusive" from the downloaded driver and then reboot the server.

hope this helps

@cismoney, and just try the power off EVERYTHING routine, make sure everything is fully booted before moving on to the next thing

Hi,
since IBM Tape Diagnotic tool (itdt) does not detect any tape, i guess you have some problems on scsi, either card or cable.
