Even this seems only to work for disk with less than 2TiB. When attaching a Hitachi 7k3000 drive on the LSI SAS/SATA ports of a Supermicro X8ST3-F board I only see 4294967294 sectors while I get 976773168 sectors when attaching to the on board SATA ports. This leaves the onboard LSI controller useless for bigger disks. Is there a way to work around this issue? Or is anybody working on enhancing the mpt(4) driver to use the newer API? Thanks in advance! Bye/2 --- Michael Reifenberger Michael@Reifenberger.com http://www.Reifenberger.com
