the proper solution to out of control cabling is ML cables. However, aside from

Hi,
I installed opensolaris on a x2200 m2 with two internal drives that had
an existing root pool with a Solaris 10 update 6. After installing
opensolaris 2009.06 the host refused to boot. The opensolaris install
was fine. I had to pull the second hard drive to get the host to boot.
Then inser

Some other points and recommendations to consider:
- Since you have the bays, get the controller to drive them,
regardless. They will have many uses, some of which below.
A 4-port controller would allow you enough ports for both the two
empty hotswap bays, plus the dual 2.5" carrier.
