Problem in creating a tar on tape

Rui Vilao — Mon, 30 Sep 2002 16:49:35 GMT

Greetings,

I am trying to backup some data on DLT tapes.

I already tried to rewind:
# mt -t /dev/rmt/1m rewind

When I start to archive I get:

# tar cvf /dev/rmt/1m /opt/oracledb
a /opt/oracledb/app/oracle/product/7.3.4/orainst/usrdfl.log 2 blocks
a /opt/oracledb/app/oracle/product/7.3.4/orainst/install.log 8 blocks
a /opt/oracledb/app/oracle/product/7.3.4/orainst/sql.log 2 blocks
Tar: end of tape
Tar: to continue, enter device/file name when ready or null string to quit.

Any help/suggestion is highly appreciated.

Thanks in advance for your help,

Kind Regards,

Rui.

Hi,

Is there a tape in the drive ?
Does the device file exist ? -> ll /dev/rmt
Did you try other tapes ?

There are a couple of docs regarding this which relate to the tape drive and type tape being used

http://www5.itrc.hp.com/service/cki/docDisplay.do?docLocale=en_US&docId=200000007948704

If not , did you check your rewind was succesful ?

mt -t /dev/rmt/0m rew
echo $?

should be 0

Hi Rui

Incase this si the isseu I would recommend :

1. Change the media and try again.

2. Try using w/o any mt option bcoz in any case the drive will write from the start of the tape .

3. If u dotn suceed change the drive , it amy be possbielt aht the drive is errorneoulsy sensing the end of tape soon , ior amy be some signal on the coneector of the controlerr is intermittent.

Hi Rui,

If another tape works okay, try "mediainit -v /dev/rmt/0m" on the tape that fails. Be sure to rewind the tape first.

I once had the same problem on a couple of DDS tapes that my (Microsoft) Network Admin had "borrowed".
