Hello Admin Wizards,

thanks to Peter Gergen, Tom Swigg and Michael Polnick who pointed me
that the disk needs to be labeled too, since it still had the old label
from the 10 GB config.

disklabel -z /dev/rz18
disklabel -wr -t advfs /dev/rz18

did the job.

Thanks for the accurate and FAST help!

Question was:

System: Tru64 4.0g, storage hardware: SW300 cabinet w/ 2x HSZ40

I had to expand my backup raid set that consisted of 6 disks. So I
deleted the old unit D200 and the raid set R2, added the six disks,
created a new raid set R2 with 12 members and the new Unit D200.
Everything seems fine on controller level; full 20 gigs of storage are
available (before: 10 gigs).

On the server, I did a rmfdmn HSBACKUP, removed the /dev/r(r)z18* files
(these having been the special files for the Backup set), and did a
/dev/MAKEDEV rz18.
New rz and rrz files were created.

I started diskconfig - but behold, there are only 10 Gigs available there.
I wonder what step I have missed and / or where the 10 missing gigs may
have gone ...

Would be thankful for any advice on that.

Thankx a lot
