I think my SCST configuration is Ok. I did experiment previously with the iSCSI target and the scst_local driver, and both worked fine. Andy, Thanks for the README. I followed the steps in the file and see the same result. The following shows the commands I'm using and the associated output. On the target side, I load the SCST/mvsas drivers and enable target mode. This looks like it works, but my 'target_mode' file is slightly different from what is shown in the README: root@ix12-1:/sys/class/scsi_host/host17# cat target_mode phy dev sas address attach dev type
