9-RELENG 20120418 compaq ciss - illegal request

[Kai Gallasch]

Hi.

I found this in the dmesg of a 9-STABLE (2012-04-18) server..

(probe0:ciss0:0:0:0): REPORT LUNS. CDB: a0 0 0 0 0 0 0 0 0 10 0 0 
(probe0:ciss0:0:0:0): CAM status: SCSI Status Error
(probe0:ciss0:0:0:0): SCSI status: Check Condition
(probe0:ciss0:0:0:0): SCSI sense: ILLEGAL REQUEST asc:20,0 (Invalid command operation code)
da0 at ciss0 bus 0 scbus2 target 0 lun 0

da0: Command Queueing enabled
da0: 572140MB (1171743324 512 byte sectors: 255H 32S/T 65535C)

If I do a camcontrol rescan the warning reappears in dmesg.

Is this harmless noise and can be ignored or a bug?

Regards,
Kai.
