Hi.
I've got a few of SAN's running in my workplace. The last two I have installed have been 2TB each. The fdisking and formatting was done with fdisk however, it did take a while but the whole process was done within an hour or so. The formatting was what took the bulk of the time. fdisk wasn't too bad at all.
I am using Red Hat Enterprise 3, Advanced Server.
Good luck.
