The only information I am looking for is the WWN identifier of the SAS target. =20 =20 I have tried to create a SCSI CDB command according the information on: <http://en.wikipedia.org/wiki/SCSI_Inquiry_Command>; http://en.wikipedia.org/wiki/SCSI_Inquiry_Command and come up with the following command:=20 =20 # camcontrol cmd da0 =96c 0x009600830112 =96i 96 =96 =20 12 is inquiry 01 EVPD bit is set 83 VPD Page 00 MSB length 96 LSB length 00 reserved =20 =20 The problem is that I cannot get any output from the command?
