My os:

FreeBSD san1 9.0-RELEASE FreeBSD 9.0-RELEASE #0: Tue Jan  3 07:46:30 UTC 2012     [email]root@farrell.cse.buffalo.edu[/email]:/usr/obj/usr/src/sys/GENERIC  amd64

I'm sure that I'm replacing the right drive.
disk2 is the disk in question, so from the server I have pulled bay 3.
0, and 1 are for the OS. 2,3,4,5,6,7,8,9,10 are for tank pool.


Can some one point me to a site or help me out by giving me some ideas.

Thank you guys.
