Tape device 1cbn path not getting created

kashif_islam · May 25, 2011, 3:40am

After we upgraded one PW450 machine from (networker 7.2 & solaris 9) to (networker 7.4 and solaris 10) through scratch installation

Only one of two HP tape drives is shown in inquire command
And we are getting strange logs in messages file (attached)
For 2nd drive 1cbn character specific file is absent.
But its patch is present in /etc/path_to_inst file

Any one has any idea how to solve this problem?

what's the output of "ls -l /dev/rmt/* "

did you try this command "devfsadm" ?

kashif_islam · May 25, 2011, 5:26am

Yes i used devfsadm -v and i also rebooted system but problem was same.

I have just checked problem is resolved by itself
I don't know how ?
Can some one help investigate

Now 1cbn is shown

I don't know, it looks fine to me now. Maybe you didn't reboot after patching the system ?

It looks fine now

kashif_islam · May 30, 2011, 2:19am

i did reboot the system but this didn't solve problem

root@laho2b# last reboot
reboot    system boot                   Tue May 24 16:46 
reboot    system down                   Tue May 24 16:43 
reboot    system boot                   Mon May 23 16:46 
reboot    system down                   Mon May 23 16:43

After the problem was resolved automatically i checked messages and found scsi errors related to HP tape drive.
somehow drive was automatically registered due to some scsi error i guess
