hi rohit,

check if your replacement tape drive is successfully detected by system. run the following:

# ioscan -fnC tape

if the status are claimed, and no special file created, then create it by running the following

# insf -ve

then try the command again.

Hi Rohit

first of all you have to check wether new tape is detect by system or not. use following cmd

ioscan -fnC tape

check the output

if ans= no

then run
insf -eC tape
then again check
ioscan -fnC tape

other wise u will also try with change the id of tape drive

hi

try
insf -eC tape

[Rohit_n]

Hi viney,
i did the fallowing command as u said
#insf -eC tape
insf: Installing special files for stape instance 0 address 10/0/15/0.3.0
insf: Installing special files for stape instance 1 address 10/0/15/0.5.0

and then i again tried
#mt rew
/dev/rmt/0mnb: No such device or address

still same problem.

#mt rew
/dev/rmt/0mnb: No such device or address

This device is listed under:
tape 1 10/0/15/0.5.0 stape NO_HW DEVICE SONY SDT-9000

I assume this tape drive doesn't exist now? Only:
tape 0 10/0/15/0.3.0 stape CLAIMED DEVICE HP C1533A

[Rohit_n]

Yes

[Dennis Handly]

Then you can only use these names:
/dev/rmt/c2t3d0BEST /dev/rmt/c2t3d0DDS
/dev/rmt/c2t3d0BESTb /dev/rmt/c2t3d0DDSb
/dev/rmt/c2t3d0BESTn /dev/rmt/c2t3d0DDSn
/dev/rmt/c2t3d0BESTnb /dev/rmt/c2t3d0DDSnb

mt -f /dev/rmt/c2t3d0BEST rew

It seems you can hardlink the new name to this old name if you want.
