3. Select to create an iSCSI target with a mapped LUN, an iSCSI target only, or an
iSCSI LUN only. Click "Next."
4. Create iSCSI target with a mapped LUN.
5. Click "Next."
6. Enter the target name and target alias. You may check the options "Data Digest"
and/or "Header Digest" (optional). These are the parameters that the iSCSI initiator
will be verified when it attempts to connect to the iSCSI target.
7. Enter the CHAP authentication settings. If you enter the username and password
settings under "Use CHAP authentication" only, only the iSCSI target authenticates
the initiator, i.e. the initiators have to enter the username and password settings
here to access the target.
Mutual CHAP: Enable this option for two-way authentication between the iSCSI target
and the initiator. The target authenticates the initiator using the first set of username
and password. The initiator authenticates the target using the "Mutual CHAP" settings.

Creating iSCSI LUNs
An iSCSI LUN is a logical volume mapped to the iSCSI target. Select one of the
following modes to allocate the disk space to the LUN:
Thin Provisioning: Allocate the disk space in a flexible manner. You can allocate the
disk space to the target anytime regardless of the current storage capacity
available on the NAS. Over-allocation is allowed as the storage capacity of the NAS
can be expanded by online RAID capacity expansion.
