System disk cloning - SGI O2&Onyx

[Gnaag]

Hello, i'm french so i'll try to be as clear as possible...

I wourld like to backup system drives on some of SGI stations here. Mirror like backups.
I found a procedure wich works very well based on xfs dump command.
My problem on that procedure is the infamous 'hearder files'. I don't understand the exact signification of that and dvhtool commands provided with my procedure did not work.

3 commands, non of them are working.

dvhtool -v creat /CYA/VolumeHeaderFiles/sash sash /dev/rdsk/dks0d2vh

dvhtool -v creat /CYA/VolumeHeaderFiles/ide ide /dev/rdsk/dks0d2vh

dvhtool -v creat /CYA/VolumeHeaderFiles/symmon symmon /dev/rdsk/dks0d2vh

I can't find if i have to replace /CYA/VolumeHeaderFiles with something or what...

And i think that without copying header files, i will not be able to boot from my clone ?

Thanks for your help !

you need the replace the /CYA/VolumeHeaderFiles with the path to where you have a copy of the sash file. If it is being created from a CD you would use /CDROM/stand.
