What is the detail meaning of the output of "mt status"?
# mt status
Drive: HP C7438A
Format:
Status: [41114700] BOT online compression immediate-report-mode
File: 0
Block: 0
Then I took OS backup using "make_tape_recovery -I -v -x inc_entire=vg00 -a /dev/rmt/0mn".
the backup completed successfully without any warning or error.
After that the output of "mt status"shows following:
# mt status
Drive: HP C7438A
Format:
Status: [81114700] EOF online compression immediate-report-mode
File: 2
Block: -1
What is meant by "File:2" and "Block: -1"?

Why do you care? Just rewind the tape.

Possibly two EOFs were written and you are on one of them, not in the middle.

Re: What is the detail meaning of the output of "mt status"?
I don't know much..but one thing is that the file number output from the status option of the mt command should increase when going forward when passing fm (file marks) and decrement when going back towards the beginning of the tape.

Re: What is the detail meaning of the output of "mt status"?
i also use tape's for backup.
before i start always check if the tape is on the beginning :
mt -f /dev/rmt/[0-x]mn stat
if the stat is like yours :
File: 0
Block: 0
the i use ignite to make a backup, after sucessfull backup, put the tape out of drive .
mt -f /dev/rmt/[0-x]mn offl
