Tapes getting ejected automatically

Question

We need to recover some older indexes. We have tried nsrck as well as scanner. They start off well but after around 10 minutes, the tape automatically gets ejected and the nsrck OR scanner running start giving media related errors.

We are currently doing Save set recovery which seems to be working fine from the same media. All backups happen good otherwise but I don't understand why it ejects tape automatically when scanner or nsrck are running and reading the media.

We are using NW 7.3.3 Build 150 all Windows environment with DDS & DSN. when running these commands, we are using the drive on the backup server & not on the DSN since we are recovering index.

Till the time media is in the drive, it reads the tape label and creates sub-folder under index folder and some 2-3 files also.

For the autochager, the timers are set to - Load sleep-5, unload sleep-5(tried 30 also), eject sleep-5(tried 30 also), deposit/withdraw timeout-15, cleaning delay-60, idle device timeout-2, port polling period-3, operation lifespan-1800 & operation timeout-1800.

Any suggestions, please help.

NW is not scanner aware - meaning that while you run scanner to BW that looks like idle device. Could be that idle device timeout simply kicks out tape because of that. As for nsrck -L7 I'm not sure as I have never tested, but I would expect NW to be aware of that operation.

I thought so but since save set recovery was ON I could not experiment with it. I wonder we need to readjust this everytime we need to run scanner.

For nsrck, I mentioned the wrong information earlier. When I run nsrck, it says NSR server busy, will retry in 30 seconds and keeps retrying for few minutes till you hit Ctrl+C to abort.

Any ideas.

busy mean that at least one resource required for operation to proceed is 'busy' with something else. As for scanner, put drive to RO mode (across all shared instances) and load tape outside NW knowledge (eg. by using sjimm).
