Individual disks are not seen in the O/S if RAID is configured on the LSI controllers (just the volume name) but disks can be not seen at all in the O/S with Adaptec (Sun STK) controllers without first initializing them.
The Adaptec based cards require all disks to be initialized first in the BIOS level setup utility before the O/S is given a device path to them.
This is the same for all operating systems installed.
So, checkout the result of the following Solaris command:
/opt/StorMan/arcconf GETCONFIG 1
You may see all the disks you have installed in a pre-configured RAID volume.
If you just see the one disk then reboot, and in BIOS select <CTRL><A> when prompted.
Then initialize the remaining disks detected in the BIOS setup utility that presents itself after <CTRL><A> is pressed.
The BIOS output will look something like this so press <CTRL><A> when you see this:

You iostat output shows it's an Adaptec (STK) card pre-configured with a RAID volume:
Vendor: Sun Product: STK RAID INT Revision: V1.0 Serial No: Size: 293.39GB <293391564288 bytes> Media Error: 0 Device Not Ready: 0 No Device: 0 Recoverable: 0 Illegal Request: 2 Predictive Failure Analysis: 0
If RAID was not configured, the details in the "Product:" field would be the drive vendor like Seagate, not the string "STK RAID INT"
So, the following command will indeed tell you all about your Adaptec (STK) RAID configuraiton:
/opt/StorMan/arcconf GETCONFIG 1
Hope this helps,
