SUMMARY: Solaris 9 install with mirrored volumes

Ok, there seems to be no way to setup mirroring from the install. I
was told instead that I'd need to do everything after the install. I
was also told that striping on a boot required disk isn't a good idea,
and that I should just mirror the partition.
The second note, is there are some partition recommendations for use of
the above links, courtesy of Darren Dunham provide some more
information on the associated details of the SVM configuration.
My current plan is to install using 2 out of 6 of my SCSI drives,
creating SVM, /usr and / partitions (no home, really - this is an
Oracle box only), and then after Solaris 9 is installed, going back,
mirroring the disk where those partitions are installed. At that
point, I'll also use the SVM to create a set of Raid 1+0 partitions on
three drives, if this is possible:
Using striping, do the following:
half of disk 3, mirrored on disk 4.
Half of disk 3 mirrored on disk 5.
Half of disk 4 mirrored on disk 5.
With the above, I'll probably put 2 SVM partitions on each drive,
including on the mirrored drive 1 & 2 combo.
Does anyone have any final comments on the above configuration?
Warnings/thoughts/etc.? The idea is to keep a hot-swap spare available
in case any drive does fail (hopefully not anytime soon). And I need a
bit more space than a single Raid 1+0 configuration. I also understand
that Solaris software RAID 5 is NOT a good idea, and thus I'm trying to
avoid that configuration by using the above.
