DLT Tape status

[Simmi]

I want to know what does the status code mean.
The fbackup utility is used to take backup on Tapes 3m and 4m. Backup on Tape 4m failed with status code 1 as in its status log file. And now the status of the tapes are as follows
> mt -f /dev/rmt/4m status
Drive: QUANTUM DLT8000
Format:
Status: [0]
File: 0
Block: 0
> mt -f /dev/rmt/3m status
Drive: QUANTUM DLT8000
Format:
Status: [41118985] BOT online compression immediate-report-mode
File: 0
Block: 0

Based on the device special file names, it doesn't look like you're working on a Tru64
UNIX system where the names would be:

/dev/rmt4h ### V4.0x
or
/dev/ntape/tape4c ### V5.xx

Also on a Tru64 system the "status" output would look like:

# mt -f /dev/nrmt0h status

Hi,

Johan is right. It seems you would have to post this question into the HPUX forum.

fbackup is HPUX.

greetings,

Hi

A man on fbackup shows the possible return codes:

fbackup returns one of the following values:

0 upon normal completion.

1 if it is interrupted but allowed to save its state for possible restart.

2 if any error conditions prevent the session from completing.

4 if any warning conditions are encountered.

If warnings occur, the operator should check the fbackup logs to verify the sanity of the backup.

It looks like the backup was interupted (perhaps it filled the tape) or something killed the process ?

Hope this helps.

Hi,
The problem is not with the drive but with the tape make.
You have to spend some time reading this doc.
