[SunHELP] How Do I......

is a good document on how to install DiskSuite and configure mirrored boot 
disks.  Disksuite is on disk 2 of Solaris (at least, it is on my Solaris8 2/02) 
./cdrom/Solaris_8/EA/products/DiskSuite_4.2.1  I have a 450 that's currently 
running mirrored boot disks and a 10 disk RAID 5 partition.  You can do both at 
the same time with no problems.  You can also do hot spares if you have the 
spindles.

The above URL should get you started and get you a mirrored boot disk.  I don't 
have a resource for the RAID5 config, but it's not too bad using the GUI (CDE 
oddities excepted)  Basically just click-and-drag a new raid5 device, then drag 
in the slices you want in the array.

The GUI is metatool.  /usr/sbin/metatool

Watch out for your metadbs (DiskSuite wants many across different disks and 
controllers) and your stripe sizes.  See other emails from the list...

Also, as I'm sure you're aware, RAID5 is slow on writes.  It's not an optimal 
solution for an Oracle database, but it works if you're on the cheap (as I am :)

Good luck
