Am getting the following when trying to perform a fbackup:

Test Plan Report (tpr) for for_backup follows .............
.....for_backup 020524 030504 starting
.....for_backup 020524 030505 Tape device is /dev/rmt/0m
.....for_backup 020524 030505 Parameter is = fbackup
.....for_backup 020524 030510 Tape is in drive
.....for_backup 020524 030510 fbackup
.....for_backup 020524 030511 fbackup error
debug info follows ... if available
fbackup(1004): session begins on Fri May 24 03:05:11 2002
fbackup(3047): could not open output file /dev/rmt/0m
fbackup(3019): would you like to enter a new output file?
fbackup(3004): writer aborting
fbackup(1002): Backup did not complete : Reader or Writer process exit

End of report

Does this apprear to be a hardware error?

Hi,

Did you try with an other tape ?
Try with tar to check your device :
# tar cv /home

Hi,

Since you do a check that the tapes is in the drive (correct ?) it could be that the tape is read-only.

You usually get this error when there is no tape mounted.

1. check protection switch on tape
2. try to use tar or cpio
3. check with ioscan -fnCtape
if there /dev/rmt/0m exist

1)Could be dirty

2)COuld be bad or write protected tape.

Thus

Try to tar to it as shown and if that doe snot work using a new tape after the drive has been cleaned .

It is Hardware

Can be various reasons ..assuming you're not doing a remote backup to a remote drive ..
1) Drive fault
2) Device file does not exist/permission
3) Tape not compatible with drive
4) Tape is write protected
5) No tape in drive

Can you run this ..
# mt -f /dev/rmt/0m status

It'll report the status of the drive and tape. If you can't run this command you might need a patch for the "status" option ..
11.00 PHCO_16748 (mt status option)
10.20 PHCO_16705 (mt status option)

Hi Lynn:

Which OS ? Did you check the following:

1) Media
2) Patch level
3) Drive
4) Check the same with another backup method (tar ?)
5) If you are using a remote backup, then check this document (TKB #S3100004479):

Hi,

before trying fbackup, to confirm whether your media and tape drive is good, try using tar

tar -cvf /dev/rmt/0m /tmp

If tar executes without any errors then you are sure that media and tape drive is good.

Then try your fbackup command again

Pls let me know what command have you given

Problem turned out to be the write protect.
Many thanks to all of you who offered suggestions.
