Attemping to make a Bootable Tape (Disaster recovery if need new HDD)
Hi Thanks for reading
We are attempting to make a disaster recovery Tape for our HP700/715 Servers running HPUX 9.05
dd if=/usr/lib/uxbootlf.700 of=/dev/rmt/0mn bs=2k ' makes the bootable section on tape (no rewind)
then
dd if=/dev/rdsk/c201d6s0 of=/dev/rmt/0m bs=1024k 'copies entire disk image to tape
Our issue is the first command to make boot seems to work ok :-
345+1 records in
345+1 record out
but second command reports :-
I/O error
7627+0 records in
7626=1 records out
And when we try to boot from tape does not see the boot at all
Help Welcome please
Andy

Re: Attemping to make a Bootable Tape (Disaster recovery if need new HDD)
Andy where are you getting this process from. HP-UX9.05 is straining the edges of my memory significantly, but I don't recall being able to boot from tape being a thing until Ignite/UX came in with I think HP-UX10.x?
Back then a more typical way of providing a "DR copy" of the boot disk was to use the offline diagnostic (ODE) utility COPYUTIL (usually available at the ISL prompt prior to launching HP-UX - may be installed on your boot disk, but may not - may have to find a support media CD-ROM)
COPYTUTIL wouldn't create a boot-able tape, but it would create a disk image that could be restored also using COPYUTIL to a fresh disk if one failed.

Hi Duncan

>>> From the hpux-700 man pages

>>> On Our system we have not any of that luxury .... Just DD and MKRS.
>>> Have just tried again as a single user but still no joy I dont understand the I/O Error and the Records In Vs Records Out Difference ?
All we need to do is get a reliable image dump from existing machine that we can put back on a new HDD should we need to ?
We have also tried the MKRS option we found on here but that didnt work either
mkrs -v -q -tdat -f /dev/rmt/0m -r /dev/dsk -m700 ' To make bootable tape
Then
fbackup -0 -i / -f /dev/rmt/0m ' File Backup
Any help at all would be great as we have six of these workhorses ......But know HDD do fail
Are any Manuals around for this version (9.05) ... All we can find is relationg to 10 or 11
Many thanks
Andy

COPYUTIL should be on an install/recovery CD (in the boot LIF partition) - do you not have one of those? I don't think it would necessarily have to be for a 09.05 CD.

Hi Duncan
We have no CD Media and NO CD Drive on the HP9000 / 715
We "Did" have tapes a long time ago but the tape streamers are no longer working and eat the tapes anyway
We have recently bought a Solid state tape emulator that uses flash media
You see our issue
