Your raidctl output at the end of your post says that, as you already know, you have two hardware raid1 mirrored drives. The disk/raid controller is presenting this pair of drives as one disk to the O/S. Control, writing and maintenance of this mirror lies solely with the hardware raid controller. The O/S thinks that it is talking to a single disk.
There is no issue if you carry out normal O/S patching on the system. Usual precautions with regards backup/recovery.
If you think this should be an abnormal process due to the presence of the hardware raid1 controller please describe why you think that.

I think that you might be being put off by the fact that the LSI hardware raid controller is integrated into the T5220.
If you had fitted an add-in raid controller card and through it's management console mirrored two disks and presented them to the host as one drive (so the host is unaware of the mirror), then the raid controller is just a SCSI controller as far as the host hardware is concerned.
What you have there is no different apart from the raid controller has been integrated by Sun (Oracle) into the hardware.

I've just received my T3-1. It has 8 disks and I would like to configure RAID1 on the disks. The Sun documentation states that you can either use the OpenBoot PROMP utility called Fcode or you can use software via the Solaris OS.

SPLITDIFF(1) Man pages SPLITDIFF(1)
NAME
splitdiff - separate out incremental patches
SYNOPSIS
splitdiff [-a] [-d] [-p n] [-E] [file]
splitdiff {[--help] | [--version]}
DESCRIPTION
If you have a patch file composed of several incremental patches, you can use splitdiff to separate them out. You may want to do this in
preparation for re-combining them with combinediff(1).
The effect of running splitdiff is to separate its input into a set of output files, with no output file patching the same file more than
once.
OPTIONS
-a
Split out every single file-level patch.
-d
Create file names such as a_b.c.patch for a patch that modifies a/b.c.
-p n
Strip the first n components of the pathname to aid comparisons.
-E
Don't use .patch filename extension when writing output files.
--help
Display a short usage message.
--version
Display the version number of splitdiff.
