Re: root partition block size problem while booting ES45

Is it in a cluster?

Is it a restore, or something similar?

It's in a simplex .Yes , i restored it from backup .During the restoration i ran dn_setup -boot to make the tape drive device files.After the restoration i had to boot in single user mode.But it failed with that error .

Re: root partition block size problem while booting ES45

I Think you have forgotten to tell the new
disk to use advfs bootblocks. Default = ufs
To do so
1) boot again from cd
2) disklabel -r dsk0 > /tmp/dsk0.dl
3) disklabel -z dsk0
4) disklabel -R -r -t advfs dsk0 /tmp/dsk0.dl
5) halt & boot from dsk0
