The SAS Controller is Smart Array P400 (256MB).* *I can setup FreeBSD 6.2R successfully and everything is OK. * *However, I found that there is an amazing message in the dmesg:* *ciss0: port 0x4000-0x40ff mem 0xfde00000-0xfdefffff,0xfddf 0000-0xfddf0fff irq 18 at device 0.0 on pci6 ciss0: [GIANT-LOCKED]* *--->**Smart Array P400 is activated by ciss0 successfully* *da0 at ciss0 bus 0 target 0 lun 0 da0: Fixed Direct Access SCSI-0 device da0: 135.168MB/s transfers da0: 419946MB (860051248 512 byte sectors: 255H 32S/T 65535C)* *--->**The Raid 5 configuration seems ok. However, it is ONLY SCSI-0 device* *The transfer speed is so slow... only 135.168MB/s transfers* ** *The output message from 'diskinfo -c /dev/da0' is:* ** */dev/da0 512 # sectorsize 440346238976 # mediasize in bytes (410G) 860051248 # mediasize in sectors 105398 # Cylinders according to firmware. 255 # Heads according to firmware. 32 # Sectors according to firmware.

Is there anything wrong on ciss0 driver or the hardware (Smart Array P400 Or SAS HD)?* ** *Thanks..* ** ** * *
