System Restore from dump

og_2 — Fri, 17 Nov 2006 03:53:53 GMT

Hi,

i'm having a small prob.

i must make a clone of an c180/hp-ux 10.20 machine on another one.

so i made a few dumps of the 1st machine (ea. main partitions dumps such as slash, usr, var etc) with "dump" utility.

i booted on the new machine with the install cd and launched a recovery shell, with network activated (works fine), and without IPL.

i loaded ioscan, mkfs and all.

but the prob is when i do an

ioscan -fnkC disk

it displays this :

[..]

disk 0 8/12.6.0 disk CLAIMED device SEAGATE ST39175LC
/dev/dsk/c0t6d0 /dev/dsk/c0t6d0s2lvm /dev/rdsk/c0t6d0s1vm
/dev/dsk/c0t6d0s1lvm /dev/dsk/c0t6d0 /dev/rdsk/c0t6d0s2lvm

[..] -> same for other disk + cdrom

(there was a previous system installed on this machine i wanna erase)

i tried to make an /sbin/fs/hfs/mkfs c0t6d0s2lvm and c0t6d0s1lvm, and mount them on a /ROOT and /ROOT/stand.

i don't really understand why partitions are named with "s1/s2 lvm suffix".

but when i rcp my slash.dump, usr.dump etc, and try to restore them in /ROOT etc, i'm getting a file system full very fastly.

any idea on how i could clone my old system on this new machine ? (without using ignite if possible)

i'm really new on hp-ux so perhaps i did something wrong.

thanks for your help.

regards,

Oliver griffin (france)

You will have a better chance of doing this properly by using an Ignite bootable tape.

In 10.20 it was call make_recovery

man make_recovery

You should only include vg00 in your recovery tape. Boot from it on the destination system restore the system itself then restore the rest of your VGs with whatever regular backup tool you are using once your new cloned system is up .

okay thanks a lot for the answer guys i'm gonna try that.

btw Must i use a tape ? or can i do it via network ? because i don't think i'll be able to plugin an lto taper on the source server.

otherwise i can do it via nfs on another server with an lto writer, but i'll still have to restore from the network in any case ?

thanks a lot.

It's simpler if you can connect a small DDS tape on your boxes, but if you can't there is the network alternative too.

Check man make_net_recovery
