next in thread | raw e-mail | index | archive | help
Have just moved to supermicro 1U boxes using 80-pin SCA drives (Seagate
ST336607LC) and U320 adaptec on-board controllers (aic7902) and the
error shown in the dmesg below crops up during bootup.
The odd thing is that it only occurs if 2 or more drives are connected;
if only 1 drive is physically attached, the boot up sequence is smooth.
These boxes are not yet in production and I hesitate to do so if the
error message is an indication of future problems. This same message
does occur in FreeBSD 4.9-Release also. The following dmesg snippet
comes from a 5.2.1-Release system:

Has anyone seen anything similar or have any ideas? these drives are
running the latest Seagate firmware and the system bios is the latest
available. Would this question be more suited for the scsi mailing list?
The message on the 4.9-Release is pretty much identical except using
pass3 in place of ses0/GEOM
