>Description:
I've got a StorCase InfoStation 12-bay SATA-to-FC SAN attached to my FreeBSD server.  It turns out that this device does not support the SCSI cmds to sync its cache.

The fix below adds the device to the list of those which require the "NO_SYNC_CACHE" quirk.


>How-To-Repeat:
Install a StorCase SAN and watch the sys logs
>Fix:
The patch below can be applied to /usr/src/sys/cam/scsi/da_scsi.c to fix this issue, but adding this storage system to the list of quirks.
