Hi, the manpage of mptutil states that mpt(4) doesn't support volumes greater 2TiB, it suggests to use the disks in JBOD mode. 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
