Hi Kannan,

I don`t think so, u your default drive is not /dev/rmt/0m...
Try with,...
# tar -tvf /dev/rmt/0mn (Tape Loaded)

If it is ok, than go-ahead...

Hope it will help u,

H.Kannan.

Hello friends,

I will try your command.. at the time i am facing # tar -tvf /dev/rmt/0mn
Tar: tape read error

Shalom,

I think one of two ideas:
1) Tape is old and been used too many times.
2) Tape was used in a different format previously to the one it is being used now.

Hi,

At first, Clean the drive head with Cleaning
catriage... Than do same procedure...

If it is failed,
# check the entry in /dev/rmt/* dir...

Check the dev file name with command:-

#lssf /dev/rmt/0mn or /dev/rmt/0m .. If the o/p is sucessfull, than no pblm in config..
Pblm may be the Tape Drive...

Verify & Revert the details,

Now i am checking this command
lssf /dev/rmt/0m
stape card instance 2 SCSI target 4 SCSI LUN 0 at&t best density available at address 0/7/1/1.4.0 /dev/rmt/0m
i am getting o/p .

Hi Kannan,

As per the o/p u got, it seems there is no pblm in config & Dev file name....

What abt lssf /dev/rmt/0mn ?...

Check it...

If this command is also sucessfull, than may be problem in u r Tape drive... (If u have another drive change it for diag)

Pls verify & give the detals..

Check you are allowed to open rewind-on-close tape devices on this system...

What is the output of:

kctune -q st_san_safe

Hi,

today i am changing the new tape.. i am facing same problem...
# fbackup -f /dev/rmt/0m -i /oradata2 -e /oradata2
fbackup(1004): session begins on Tue Apr 8 09:13:21 2008
fbackup(3038): output file /dev/rmt/0m is not a valid device file for backup
fbackup(3019): would you like to enter a new output file?
n
fbackup(3022): would you like to continue this session?
n
fbackup(3004): writer aborting
fbackup(1002): Backup did not complete : Reader or Writer process exit
#
===============================
As instruction i am using the command i got bellow o/p..
# lssf /dev/rmt/0m
stape card instance 2 SCSI target 4 SCSI LUN 0 at&t best density available at address 0/7/1/1.4.0 /dev/rmt/0m

# lssf /dev/rmt/0mn
stape card instance 2 SCSI target 4 SCSI LUN 0 at&t no rewind best density available at address 0/7/1/1.4.0 /dev/rmt/0mn

#
# kctune -q st_san_safe
Tunable Value Expression Changes
st_san_safe 0 Default Immed

So you can open a rewind-on-close tape drive.

Let's take fbackup out of the equation and see whether we can successfully stat the device even:

mt -f /dev/rmt/0mn status
