I had also logged a case with sun with regard to this, seems the devices are present under O.S but this were not shown under cfgadm -al,iostat -En or under /dev/rmt/ * output but when i give cfgadm -alv, it does shows the devices.I have done previously a reconfiguration reboot but Sun has advised to do a probe-scisi-all from O.K prompt.I will give it a try today and let's see Smilie

Hi Sahil,

Did you apply the latest Solaris 10 Recommended before the lu starter patches?

Regards

When you probe-scsi-all, if the library isn't listed try very hard to get it listed by resetting the library, power cycling the library, wiggle the scsi cables, replug the cables, et al. While the system is down (ok prompt) gives you the opportunity to run probe-scsi-all repeatedly to see what's there.

To your credit you assumed that the problem was caused by lustarter patching (which is the correct approach for an IT pro "last thing I did caused the problem"). It is however possible that the reboot caused the issue to appear not the lustarter patch. I would begin to think outside the box at a coincidence occuring.

Repeat, try very hard to get probe-scsi-all to see the library whilst the system is down. Might also power cycle the M5000 if you can't get a result.

Still no luck.Below is the output from ok prompt.I see tape library here but sill nothing under /dev/rmt/*.

Hi Sahil,

The general recommendation from Oracle is that the latest recommended are applied first and then the LU, also I'd be tempted to check that all the firmware levels are compatible.

Including the SCSI adapter and the Tape Array, don't forget the HBA's and the ILOM. Generally the vendors will have a support matrix some where and you'll have to put every thing together your self.

Regards

Dave

More directly:
@sahil_shine - showing us errors and confugrations does not answer basic questions:

what is your patch level? Are you current?

We have to rule out possible problems before we can give you a good answer.

Old 09-23-2012
You mention that there is now nothing in /dev/rmt.

Numerous times I have seen a patching operation wipe out network gateway and default router files information but I have not seen it affect tape library configurations. However I guess that it's possible that the /dev/rmt 'special node' files are all that is missing. Do you have any other backup of this system other than on the library that you cannot communicate with? If so, you could try restoring /dev/rmt/*

If it's only the /dev/rmt device node that's missing you might just be able to communicate with the library again.

What backup software are you using? Do you know how the tape library was configured in the first place and where its configuration files are?

I know that NetBackup can lose communication with a library but NetBackup provides a button within to rescan for devices and doing that normally fixes things.

As others have mentioned, recheck firmware levels, et al. Also, no harm in continuing with the full recommended patchset.

Also, as someone else has said, what about the library device firmware level; perhaps that's too old.
