Last week we discovered a problem with a number of our new systems that contained Adaptec 2940UW Revision E chips. All systems containing the E revision chips are failing under load with SCSI resets. The 'D' revision works fine in those systems. Our hardware vendor is trying to get some information out of Adaptec on this problem, but it almost looks like they discovered a bug in that version and yanked it. All Adaptec 2940's coming out of the channels now seem to be Revision 'D'. You can check dmesg to determine what version you have. ahc0 <Adaptec 2940 Ultra SCSI host adapter> rev 1 int a irq 9 on pci0:13 The "rev 1" is the E revision and "rev 0" is D. Dropping the transfer rate to 10mbs/sec on all your drives will also correct(hide) the problem. Greg On Apr 18, 11:32am, Raul Zighelboim wrote: > Subject: Help !
