                          I have a CentOS 7 machine with iSCSI configured. see ls output from targetcli below. I want to add disk02 to lun0 so that to the iSCSI client can see a total 869.16GB instead of 392.2GB 

Question: Is it possible to have lun0 use the combined capacity of disk0 and disk1 and if so how to do that with targetcli on CentOS7.
