It drive change to action by firmware revision, after all... -- Makoto Murakami <mako2@din.or.jp> State Changed From-To: open->closed Problem was apparently solved by upgrading hardware's firmware. |
I use Tekram DC-390 SCSI Host Adapter and IBM DORS-32160 Harddisk Drive. DORS-32160 S82C have some problem when tag queueing enable, So tag queueing disable on SCSI BIOS. But, I cvsuped amd.c rev 1.5 -> rev 1.9, SCSI BIOS setting is ineffectual. Accordingly, I add fix for cam_xpt.c. Detail is shown below: (# camcontrol negotiate -n da -u ? -T disable is no effect.) { /* Broken tagged queuing drive */ { T_DIRECT, SIP_MEDIA_FIXED, "IBM", "DORS*", "*" }, /*quirks*/0, /*mintags*/0, /*maxtags*/0 }, How-To-Repeat: configuration: use AMD 53c974 based SCSI Host Adapter and connected IBM DORS-32160 S82C drive.
