I rebuilt the kernel with the 2200 f/w compiled in and included Ken's patch and the machine now recognises the drives. It also thinks the first LUN is a disk but gets an error trying to access it. The other two LUNS which really are disks now work fine. I get the following from rawio bash-2.04# ./rawio -a -I ESS-FC -v 1 /dev/da1c Test ID K/sec /sec %User %Sys %Total RR ESS-FC 8396.3 522 0.2 4.3 4.4 16384 SR ESS-FC 21633.9 1320 0.4 9.7 10.1 16384 RW ESS-FC 5498.9 340 0.2 2.6 2.8 16384 SW ESS-FC 18207.9 1111 0.3 8.3 8.6 16384 > I'm very curious as to any issues you might run into with the Shark. Please > let me know how it's going. Well the Shark doesn't natively support FC yet so we're using a "SAN Data Gateway" to map SCSI LUNS to FC LUNS. Native FC support for the Shark is expected soon so I'd expect better performance when it does. Thanks Carl.
