To use this feature, click "Add a Policy". Enter the policy name and the initiator IQN, assign the
access right for each LUN created on the NAS and click "Apply".
For descriptions on each field, refer to the table below:
Field
Description
Read-only
The connected initiator can only read the data from the LUN.
Read/Write
The connected initiator has read and write access rights to the LUN.
Deny Access
The LUN is invisible to the connected initiator.
If no LUN masking policy is specified for a connected iSCSI initiator, the default policy will be applied.
The system default policy allows read and write access from all the connected iSCSI initiators. Click
the default policy and "Edit" to edit the default policy. To delete a policy, select a policy and click
"Delete".
Note: Make sure at least one LUN has been created on the NAS before editing the default
LUN policy.
Hint: How do I find the initiator IQN?
Start the Microsoft iSCSI initiator and click "General". You can then find the IQN of the
initiator.
Snapshot
QNAP Snapshot can be used with iSCSI LUNs and volumes in a QNAP NAS to achieve full protection.
With the QNAP Snapshot Agent, the NAS provides application-consistent snapshots by capturing all
data in memory and all transactions in process before performing the snapshot. The application will
then be consistent and include all necessary data. In case of snapshot restoration, no data will be
missing.
On this page, you can take, manage, or restore application (or crash consistent) snapshots on
block-based LUNs or check a list of servers with Snapshot Agent installed and set up remote snapshot
replication jobs.
Note:
 Snapshot Replica (or volumes/LUNs replication between remote servers) is covered in
Backup Station. For details, please refer to the Snapshot Replica chapter in Backup
Station.
