Hello everyone,

I'm running HP 10.20 on D370 class. I had been trying to make a make_recovery tape and ran into this problem, the system hang at this screen for over 2hours and then the system asked for the new tape. The DLT tape I had can contain over 40gigs of data - but the system keep asking for 2nd and then 3rd volume. I had clean the tape drive use new tapes (DLT and DDS), I even download a new software "ignite_10.20.tar" from the site and installed as per instruction - still, I'm into my 2nd hour of the make_recovery. Can someone shed some light into this for me.

By the way, I had no problem creating make_recovery tapes for my 3 other systems with bigger (2x) file system than this one.

Thanks

What options are your specifying to do a make_recovery?.

I wonder if you kept everything under your root volume group. Try this command

make_recovery -v -A -C -d /dev/rmt/your_tape

If your /usr is part of another volume group, then everything under that volume group will be backed up otherwise it will backup only the root volume group.

This is the command that our sysadmin had in his script and it is the script we use for all the systems:

/opt/ignite/bin/make_recovery -A -v -b /tmp/uxinstlf.recovery -d /dev/rmt/1m

Thanks.

You should use 1mn for the tape drive.
that means no rewind
the 1st file put onto tape is the LIF area
then make_recovery does the archive into the second fileset
you can test to see if a tape is good mt -mt /dev/rmt/1mn fsf 1
tar -xvf /dev/rmt/1m directory_path
or
tar -tvf /dev/rmt/1m to list contents of the tape

I had problems when I did not used 0m as a tape device on one system. It did work on other systems though.

Hi Eileen,

When I tried to do the command:

# tar -tvf /dev/rmt/1m
Tar: blocksize = 4
directory checksum error

I'm now trying to do to /dev/rmt/1mn instead /dev/rmt/1m and see how it works.

Sorry, I messed up my last message.

mt /dev/rmt/1mn fsf 1

will forward skip the tape past the LIF area
then you can list the contents or restore something from the tape.

I did have a problem when I used 0m on one of our systems. The make_recovery tape was no good.

I've sometimes had problems using a tape for make_recovery that had been used elsewhere. Mediainit /dev/rmt/1m fixed my problem however my make_recovery was not running for 2 hours before asking for another tape. Then again, I was using a DDS III drive instead of a DLT.
