I think what you're asking is to change the name of the device file, like from /dev/rmt/whatever to /dev/rmt/0m. Well, it's just that simple: rename it.

mv /dev/rmt/whatever /dev/rmt/0m

Also do all the associated device files like /dev/rmt/whatevern to /dev/rmt/0mn so that everything is consistent.

Hi,

please check
- the device names reported by your ioscan: is /dev/rmt/0m found here?
- is there medium in the drive?
- does a 'mt -f status' report the same error?

I changed scsi id from 2 to new scsi id 3.
Then I did insf -H (new path )
and ioscan -fnCtape to checked new device file and it look ok.
tape 3 0/1/1/1.2.0 stape NO_HW DEVICE HP C5683A for old device

and for new device
tape 0 0/1/1/1.3.0 stape CLAIMED DEVICE HP C5683A

but if I want to use new device file for tape on scsi id 3 which was 3 (claimed )
i got error
cannot open /dev/rmt/0mn

Only rebot can help.How can I fix this witout reboot.

Hi,

Please do

#ioscan -fnCtape
#insf -eC tape
#ioscan -funCtape -- Now you can see the claimed one

Move the rewind and non-rewind device files
like /dev/rmt/xmn /dev/rmt/0mn so on.

run insf -e or insf -d stape and the new device file will be created. use that device. It will be /dev/rmt1

Or if u want to use previous device

do rmsf -H on the old path and rerun ioscan and insf again
