Hello, recently I've acquired Infortrend EonStor A16U-G2421 array with 16x 500GB SATA drives inside. It is connected via: 04:00.0 SCSI storage controller: Adaptec AHA-2940U2/U2W to host running Fedora 12 with following kernel: 2.6.31-0.33.rc1.git2.fc12.x86_64 When I export LUN >2TB from array I got following errors: scsi 5:0:0:1: Direct-Access VW VRU1610 347G PQ: 0 ANSI: 5 scsi target5:0:0: FAST-40 WIDE SCSI 80.0 MB/s ST (25 ns, offset 127) scsi5:A:0:1: Tagged Queuing enabled.

I was under impression that aic7xxx supports them, but it seems not true. What can I tweak on the Linux side to use 6TB volumes?
