Make tape backup

Jeff Hagstrom — Fri, 06 Mar 2009 19:42:05 GMT

I did a make tape recovery tape:
make_tape_recovery -x inc_entire=vg00 -I -v -z /dev/rmt/3mn
Everthing looked fine until the end, I got an error:

pax: write : I/O error
pax: A write error has occurred.
warning: the pax command returned a non-zero exit status (exit status 1 )

I included the report.

What are the pax write i/o errors?
Did i do the make tape correctly?

HPUX 11.11 on a RP7410.

post

$ tail /var/opt/recovery/latest/flist

Those are just warnings. More likely those files, all of them were in temp file system, were deleted and can not be found when been backed up.

An I/O error is generally a problem with either the tape or the drive. Use a cleaning tape on the drive, then try a new tape and see what happens.

Does the pax: write : I/O error have something to do with the missing files?

Or is that a seperate issue.

>> No, this issue is with the tape

>> The missing file is a different issue for the last two warning you have received.

I've faced the same issue and that was because of a bad tape.
The command I used was "nohup make_tape_recovery -x inc_entire=vg00 -a /dev/rmt/0mn 1>/tmp/mtr.log 2>/tmp/mtrerror.log &".

Hi Jeff
Pls use new tape and use below command

#ioscan -funC tape

# make_tape_recovery -a /dev/rmt/3mn -I -v -x inc_entire=vg00

Example:
# make_tape_recovery -a /dev/rmt/?mn -I -v -x inc_entire=vg00

Hi Jeff ,

ioscan -fnC tape (will show are you tape drive attached)

assume you DDS4 - drive to make tape backup.? also from the above command can you check , whats you path for you DDS4 tape drive?

by default either 0mn (or) 1mn

# mt -f /dev/rmt/0mn status (will show tape inserted and ONLINE)

# make_tape_recovery -AvI -x inc_entire=vg00 -a /dev/rmt/0mn

(if still got some issues)

Please post below output

# ioscan -fnC tape
# tail -50 /var/opt/ignite/recovery/lastest/recovery.log

Thanks,
Johnson
