Check the tape status:

mt -f /dev/rmt/0m status

If it does not respond (note: the status command only works with 11.00 and higher), then the tape has likely failed. The HP35480A tape drive is very old and cannot use any tape except DDS-1.

#ioscan -fnCtape

see that the device is CLAIMED.

Hi Ammar ,

Check with ioscan first.

1. # ioscan -fnC tape [ it should be CLAIMED ]

2. # mt -f /dev/rmt/0m status [ If the tape is in the drive it will show the status output. ]

3. then check the command,
sudo tar cf /dev/rmt/0m /tmp

Hi Amar,

If you still gets error after step.3 , seems you dont have enough sudo permission ,

Check sudoers file also ,(/usr/local/etc/sudo/sudoers )

Cheers,
Raj.

Looks like the tape(drive?) failed.

Perhaps you could try this as root and avoid the sudo factor.

It appears you have no tape in the drive.

Verify that there is actually a tape in the drive.

Just try "mt rew"

If you have tape in, you should be able to rewind it successfully as hardware is claimed and device file is created.

I guess you don't have to use root for this. You can try with your id. You may have problem while writing files for which you don't have permission.

I would suggest to use v options with mt..."mt -cvf /dev/rmt/0m /tmp". It will show if it is writing files.

Hi,

If the tape is loaded in drive while mt status show this, the drive is failed.

Hi Amar ,

from the status , it seems that there is no Tape loaded in the drive.

If tape loaded in the drive it will show the status like this :

-----------------------------------------
# mt -f /dev/rmt/0m status
Drive: HP C5683A
Format:
Status: [41112600] BOT online compression immediate-report-mode
File: 0
Block: 0
-----------------------------------------

If this is the case , you can try after loading a tape.

Cheers ,
Raj.

Amar,

If the tape is loaded , and its not sensing , it means problem with the HP35480A drive , and need to log hardware call for that.

Raj.

Hi Ammar

1. Check EMS logs and syslog.log file for errors logged

2. If drive is able to load the media properly try mt /dev/rmt/0m and see if drive responds

3. IF above step does not help, Drive electronics has failed.Log a call to local HP support provider

Mahesh
