Hi,

Could you post or attach the ioscan -fn output?

Is the stape driver configured in your kernel?

try to chage the scsi id switch setting on tape drive a nd reconnect the tape drive.
run:
#ioscan
#insf
see wether drivers got installed or not

u can also try insf -e

ioscan -funCtape|grep -i tape

see the path

mt -f /dev/rmt/xmn rew

[MarkSyder]

You have run your mt rew command with a tape device of 0, but ioscan shows 1. Replace the 0 with a 1 and try again.

Hi sandeep

i tried
# ioscan -funCtape|grep -i tape
tape 0 10/0/15/0.3.0 stape NO_HW DEVICE HP C1533A
tape 1 10/0/15/0.5.0 stape CLAIMED DEVICE SONY SDT-9000

i get the fallowing message.

[Robert-Jan Goossens]

Hi,

Mark gave you the answer.

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

If you use mt without defining a device it will use the default 0mnb device.

Try to use

# mt -t /dev/rmt/1mnb rew

Hi
i just tried
#mt rew

the also it dont work.

[Problem]

Hi

I tried as

#mt rew /dev/rmt/0mn

#mt rew /dev/rmt/1mn

#mt rew /dev/rmt/0mnb

# mt rew /dev/1mnb


then aslo it dont work

[Robert-Jan Goossens]

Could you post

# ls -la /dev/rmt/1*

and

# mt -f /dev/rmt/1mnb status

[Sandeep_Chaudhary]

mt -f /dev/rmt/1mn rew



this is enough

[Problem]

Hi

Sandee

i tried the

# mt -f /dev/rmt/1mn rew
#

but it comes agian to hash promt.

[Pete Randall]

The drive has a new device file. You can simply rename this, like so

tape 1 10/0/15/0.5.0 stape CLAIMED DEVICE SONY SDT-9000
mv /dev/rmt/1m /dev/rmt/0m
mv /dev/rmt/1mb /dev/rmt/0mb
mv /dev/rmt/1mn /dev/rmt/0mn
mv /dev/rmt/1mnb /dev/rmt/0mnb

Then you will have you default drive back and "mt rew" will work.

"i tried the

# mt -f /dev/rmt/1mn rew
#

but it comes agian to hash promt"

Without an error message? That would suggest success.

> it comes agin to hash promt and unable to rewind the tape

exactly as it should. There is no response from a successful rewind command.

Hi Rohit,

If it comes back to hash prompt after you run mt rew, this means that the tape rewinding is successful. You should now run "mt status". It will show you something like the below.

Status: [41114200] BOT online compression immediate-report-mode.

The BOT in the above output means "Beginning Of Tape", which means the rewinding is successful.
