Tape drive busy status

Hello All,

I am using HP-UX 11.12 OS. today i was restoring some data from tape drive using SAM but in the process I aborted the operation as I want to restore some specific folders only to get restore not whole disk. So i cancel the process by pressing Ctrl+C but now my system shows device is busy. Also after pressing the Ctrl+C i am getting some Y/N kind of options i press N to each but it goes many times. Now my drive in busy state so how can i make it to normal state and how should i get restore specific folders on from my tape, i have the whole tape list.

A quick response is much appreciated.

Thanks & regards,
Pravin.

Re: Tape drive busy status

if possible please restart( power cycle) the tape drive.

then insert the tape & rewind it before restore.

#mt -f /dev/rmt/0mnb rew

First device will have name such as /dev/rmt/0m, /dev/rmt/1m and so on.

after that you try..

Ani

(Was that 11.11?)
Have you killed all of the processes that were using the tape?

I suspect it is a patch problem. Load the latest SAM cumulative patch and any dependencies. Please don't forget to assign points.

Re: Tape drive busy status

My /var folder was 100% full as it is mounted on some other VG disk so i think this might cause the error!!!!!

Clean you /var and make some space, everything will be ok.
