Dear All, I am trying to use “camcontrol cmd –c” to send a scsi inquiry command that lists 0x83 (device identification) data instead of the standard output given by the “camcontrol inquiry” but I cannot get it to work properly. This could be due to that I am not understanding the hex format, so hopefully someone out there can point me in the right direction? The only information I am looking for is the WWN identifier of the SAS target. 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: # camcontrol cmd da0 –c 0x009600830112 –i 96 – 12 is inquiry 01 EVPD bit is set 83 VPD Page 00 MSB length 96 LSB length 00 reserved The problem is that I cannot get any output from the command? Am I using it wrong? Thanks, Björn
