I have 2 880 servers that I have a question about disk partitioning.
I don't have a license for the Sun Solstice software, much less a
maintenance support.
(don't ask me, I didn't buy these much less spec them out). By
default, the Solaris 8 install defined a root and swap slice (0 and 1
respectively) on the other five 36GB drives. since they are not
mounted - I believe that I can reassign the space to other partitions.

Yes/No? Please advise.

Sure.

And it wasn't the Solaris 8 install that put that partitioning on them,
that's just the way they come from Sun.

Yes, you can reassign them, so long as you ahven't mounted them, built
filesystems and the like, otherwise it will blow away all your data. use
the format command, reassign the partitions and label the disks, then
you are ready to go.

Here is the VTOC for the disks ...

I inserted carraige returns for clarity. Disks are mirrored in pairs
from top to bottom, you can see the symmetry.

I hope that this has been of some value.
