Hello,   With Linux, like any OS, iSCSI is no different from SAS/SATA or Fibre Channel.  Regardless of how you get connected to a "disk" it looks like a SCSI disk to the OS.   So yes you use mount points.   That's how Linux like most UNIX OS's do it.  But any supported method for other disks work with iSCSI.   I.e. in Windows you can use drive letters, or mount points.
