iSCSI Essentials
p. 225
iSCSI is the protocol with which one communicates with the server. The Target is the shell with
which one harbors and performs with files and a LUN is the Volume that will eventually be mounted
and formatted by a client computer’s iSCSI initiator. G-RACK 12 makes LUN creation simple by
automatically generating a one-Terabyte allocation within the workspace.
If you choose to, you may edit that LUN or create addition LUNs within a Target resulting in multiple
Volumes much like a partition for a Directly Attached Storage device (DAS). However, you should
know that once a G-RACK 12 iSCSI target has been initialized by a client computer you will not
be able to grow a LUN without wiping out all of your data. So plan accordingly and always make
backups of your files.
Edit LUN
If you want to grow (increase the size of) your auto-generated one-Terabyte LUN, do this BEFORE it
has been mounted and formatted by a client computer.
Navigate to the iSCSI SCST under the Connect menu
Highlight the target your desired iSCSI Target and press the Edit LUNs list button.
