Re: fbackup

Kevin,

Do a "mt rew" and see what results you get.

Re: fbackup

There should be a space between -f . Can you please post the ioscan output and the fbackup command?

Re: fbackup

when running mt rew /dev/rmt/0m its returning a "/dev/rmt/0mnb: No such device or address" Which is strange..why is it grabbing the 0mnb device file

Re: fbackup

Hi (again) Kevin,

The mt command should default to /dev/rmt/0m if you don't specify a device (with the -t option). I wonder if your device files are corrupted. Do "ll /dev/rmt/0*" and see what you get. We may want to remove them with "rmsf" and recreate them with "insf -e".

Re: fbackup

I have experienced similar problems on a seemingly good tape drive. I tried changing the tape and found that I had a couple of bad tapes. They were pitched and never to be seen again. Just because a tape is new or not very used, doesn't seem to matter. So even if it is a brand new tape out of the box it could be deffective.

Re: fbackup

Ok I missed the part about no such address or device. Have you tried reinstalling the device files for that tape:

insf -H (hardware path)
example insf -H 52/2/1.0

Re: fbackup

Kevin,

Maybe the "mt rew" wasn't such a good idea. I just tried it and, without a tape in the drive, I get the same "/dev/rmt/0mnb: No such device or address" response as you're seeing. Can you try it with a tape in the drive?

Re: fbackup

Not to be picky but your commnd:

mt rew /dev/rmt/0m

should be

mt -t /dev/rmt/0m rew

Maybe you are typing it correctly but not quoting accurately in your response. Now is this something that occured recently but was working in the past? If so I would suggest that you call HP and have them determine if it is a bad drive or not. Or if you have another drive can you do a:

mt -t /dev/rmt/1m rew
after you put a known good tape in the drive.

Re: fbackup

At the risk of sounding insulting,....

Are you telnet'd onto the correct physical server? (try the console)

Are you querying the right physical device? (Trace the cables)

Don't laugh, people here have been caught out before!

Re: fbackup

Hi,

Has someone linked /dev/rmt/0m to the other device file? Check using ll and lssf.

Also fbackup shouldn't be used with no rewind device files (there was mention of one earlier on.)

regards,

Darren.

Re: fbackup

What is the minor no. for /dev/rmt/0m and /dev/rmt/0mnb? Can you please do a "ll" on your /dev/rmt directory and post it over here?

Sandip
Good Luck!!!
