I know that 6GBIT SAS HBAs with LSI 2008 Chip are in the default kernel since 2.6.33- patches are available. The Disksize shouldn't matter. > My problem under BSD is 2-fold: > > 1.

My smallest disk is 2TB is this a problem? When you have a driver, it is recognized. Your largest disk is probably also 2TB ;) > Without visiting the datacentre, I have no device to install to. even when visiting the DC, I suppose. I know of some 3GBit HBAs beeing able to be upgraded to Raidcontrollers (linux driver changes from mptsas to megaraid_sas). But this is not possible with all LSI devices. Afaik we don't have a driver for freebsd yet. Regards, Michael!
