PCI-X Ultra320 SC SI card
This document is classified as Normal
I've been meaning to post a patch, but haven't gotten to it yet. The
setup I tested with was similar (WinXP initiator and targ(4)). It
appears that Windows sends a REPORT LUNS command which scsi_target
doesn't support. In turn, the unsupported command causes scsi_target
to abort. Here is a partial patch of the changes I made (this is
against 4.9). Note that the CVS logs for scsi_target make some
reference to a fix for REPORT LUNS, but I haven't looked into it at
all.
