It's the SCSI Target ID, you can compare this to the CTD number that the host sees, It's referred as the hardware path that can be specified on Symmetrix
May be this is a simple question.But I want to clear by doubts.  map dev 20E6 to dir 09D:1 target=0, lun=26;  map dev 20E6 to dir 09D:1 target=0, lun=26;   what does this taeget mean ?
Target in the mapping command
