Showing Device Does Not Exist While Taking Backup

Friends, while taking backup on /dev/rmt/0cn it is showing device does not exists.

I have checked /dev/rmt 0cn is present there with link file created in /devices/pci@8,700000/scsi@5/st@5,0:cn

I have checked cd /devices/pci@8,700000/scsi@5 but st@5,0:cn is not there. But I found st@3,0:cn.

Then I checked /usr/adm messages files. It is giving these doubtful lines.

more messages |grep st@3*

Have you tried running the devfsadm command?

Yes i have tried running devsadm in /usr/sbin...but still there is no related st@5 files in /devices/pci@8,700000/scsi@5 which are linked with the /dev/rmt/0cn..


I am getting these infos also from the messages files.


root@host1:/usr/adm

It should read as "devfsadm" (not devsadm) in my previous post..sorry for that..
