c1t0 is the disk that's currently 'live' and contains Solaris 8. We're attempting to build a dual OS system.

The restored version was originally on the other disk - would this cause a problem now? Does the restored kernel need to be rebuilt because the hardware layout is different?

Many thanks, p

what do you exactly mean with a different hardware layout? you said that it is the same hardware, didn't you?

anyhow, you can force a kernel update/reconfiguration with the "-r" option at boot time
"boot disk2:0 -r"

have you tried to restore your backup like it was before, everything in one slice? perhaps your backup is corrupt. normally, if it is the same hw-platform, you just need to restore the file-systems, edit your /etc/vfstab, install a bootblock and everything works again.... do you have any /etc/system entries that point to the old disk, like "rootdev:/dev...."

i would try to restore the backup in one slice, to see if it would work, after that you can go step by step to see what's not working...

Hi Pressy,

I think I'll try this option "boot disk2:0 -r"

Yes the HW is the same but I meant that it will look different to the OS because it's now on the other disk... Make sense?

I shall check the /etc/system entries now... nope, nothing in there mentioning disks or anything that sounds like it could be related...

Thanks again, your support is much appreciated Smilie
