Does anyone here know how to install solaris 8 and/or 9 having the root filesystem being on a pair of mirrored disks? I can't find any howtos, and the manual for the machine is being less than obvious when making references to installing on the multi disk setup.
Taking that a step further, can it be installed with the root filesystem on a software raid 5? (Or is there a hardware raid controller on the FC-AL disk cage in the v880 that I'm missing?)
I've installed solaris on a billion machines a billion times, but never on good hardware that has multiple disks in it. 🙂

If you're using Solstice Disksuite, you install the OS then mirror.
Make sure to leave enough room at the end of the discs for a metadata slice.
Catch me in the usual places later today (have a conference to go to at 8:30-11:30 today) and I'll explain further if you need it.
More importantly, why do you need a raid-5 for the root of all things?
Because the important parts of the filesystem are going to be on an EMC, the machine has 3 disks in it that will otherwise go unused but to hold the root filesystem, might as well employ them all.
Then you can offline one and back it up snapshot-style while not compromising the mirror integrity.
And you also get three metadata databases as a result, which is also A Good Thing as Solaris wants (by default) half the databases working in order to boot.

Do a three way mirror.
Seriously.

modify to suit your tastes. you wouldn't believe how much i had to do this shit at CGI.
also, the parent resource, http://www.blacksheepnetworks.com/security/resources/index.shtml has a shitton of good info.
