Tar : end of tape problem

Hi,

I have been trying to send a single file to my tape drive using tar, I used the following commands..

#/root # ioscan -fnC tape
Class I H/W Path Driver S/W State H/W Type Description
==========================================================================
tape 0 0/0/8/1/0/1/0.1.0 stape CLAIMED DEVICE HP C5683A

#/root # echo $?

#/root # tar cvf /dev/rmt/0m /etc/passwd
a /etc/passwd 6 blocks
Tar: end of tape

Tar: to continue, enter device/file name when ready or null string to quit.
User entered a null name for next device file.

Drive: HP C5683A
Format: DDS-3 format
Status: [41112500] BOT online compression immediate-report-mode
File: 0
Block: 0
#/root #


It is a tiny file and it reports as if the media was full...

Please advise.

Thanks.

Re: Tar : end of tape problem

I have seen this with my bad tape drive.

Try to clean the drive, use another tape and finally consider a drive replacement.

Hope this helps!
Regards
Torsten.

Re: Tar : end of tape problem

Shalom,

I'd try new media, cleaning drive and then HP Hardware if the first two things don't work.

Re: Tar : end of tape problem

Hmm.. Did you try via other backup utilities,

eg: fbackup or cpio ??

Re: Tar : end of tape problem

Actually I need this tar to work, because that is the format used by the ignite tool, the back end of the problem are ignite jobs failing because of this.

Re: Tar : end of tape problem

fbackup did not work... I guess I'm calling HP

Re: Tar : end of tape problem

This confirms that the issue might be due to due to Bad tape.
I would advice to clean the tape or use the recommend tape for taking backup.

Re: Tar : end of tape problem

"fbackup /etc/passwd -f /dev/rmt/0mn "

to start with, i believe you have a useage error...since it threw out /etc/password

try something like

fbackup -f /dev/rmt/0mn -i /etc

Re: Tar : end of tape problem

The tape drive has been cleaned.

This is the output of the mt command

[root]:/root # mt -t /dev/rmt/0m status
Drive: HP C5683A
Format: DDS-3 format
Status: [1112500] online compression immediate-report-mode
File: 0
Block: 0

I also tried an fbackup as adviced in the other thread but got I/O error messages.

Re: Tar : end of tape problem

Shalom,

Additional advice:

Try a new tape.

Check that the write tab on the tabe is in the proper position to permit write to tape.
