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.

NAME
vparutil - get and set SCSI parameters for SCSI controllers from a virtual partition
SYNOPSIS
dev_path
dev_path
dev_path scsi_id] scsi_rate]
DESCRIPTION
The command gets and sets SCSI parameters for SCSI controllers within a running virtual partition. When setting the SCSI parameters using
the option, the virtual partition which owns the specified SCSI controller must be in the down state. If not, the command will fail with
the appropriate error code.
The SCSI parameters for a given SCSI controller must first be set (from the firmware BCH prompt or using the option) before the parameters
can be retrieved using the option.
The command is allowed on Itanium(R)-based platforms for compatibility. No action is taken for the command.
Options
recognizes the following command-line options:
Deletes an entry for the specified SCSI controller at
dev_path from the SCSI table.
Gets the SCSI parameters for the specified SCSI controller at
dev_path.
Sets the SCSI parameters for the specified SCSI controller at
dev_path.
Operands
recognizes the following command-line operands:
dev_path The device path of the SCSI controller.
id The SCSI ID for the specified controller (defaults to 7).
rate The SCSI rate for the specified controller. This parameter can have one of two values: for the corresponding fast wide and
ultra wide SCSI interfaces.
Note
For managing SCSI controllers, use corresponding SCSI utilities. For further information refer to
SECURITY RESTRICTIONS
This command is restricted to processes owned by superuser.
When virtual partition flexible administrative capability is enabled, only a Designated-Admin vPar can set SCSI parameters for SCSI con-
trollers.
EXAMPLES
Set the SCSI ID for controller at 0/0/2/0 to 3 with the fast wide rate:
RETURN VALUE
Successful.
Invalid SCSI controller specification.
Invalid SCSI ID.
Could not communicate with virtual partition monitor.
Virtual partition which owns SCSI controller is not in down state.
Internal firmware call failed.
Other error.
