You can use soft partitions on top of hardware RAID.  Suppose your
hardware RAID'd disk is visible to the OS as c1t0d0 and you have
slices 6 (many gigabytes) and 7 (<100MB) available:

# Create the metadatabases
metadb -a -c 3 -f c1t0d0s7
# Create 30 soft partitions, 500 MB each
i=1000; while [ $i -lt 1030 ] ; do
   metainit d$i -p c1t0d0s6 500m
   newfs /dev/md/rdsk/d$i
   i=`expr $i + 1`
done

Thanks,

ZFS wouldn't appear to be an option here as we are only dealing with a
pair of internal disks with no SAN-attached storage.

I have a proposed config on T2000 that will use the HW RAID to mirror
the internal disks. So with a limited number of physical slices on the
internal disks, we are looking at having several zones sharing a single
partition for their zonepaths, like all under /export/zones

/export/zones/zone1
/export/zones/zone2
/export/zones/zone...

SVM with soft partitions is not an option and there will be no SAN
attached storage to mount small slices for zonepaths. Other than the
obvious issue of zones sharing a single partition (disk slice), are
there any other concerns with this configuration?

  
  
Yes.  Running out of space on 1 zone will affect all other zones on
the same slice.  We ran into problems with this config because we
cannot guarantee that we do not have a rogue zone.

For this config, HW RAID is a non-negotiable requirement and SVM cannot 
be used to mirror the internal drives. It comes from a historic aversion 
toward the old SDS (Disksuite Suite).

Just out of curiosity, why are soft partitions not an option?
