iSCSI Target Status

Status

Description

Ready

The target is accepting connections but no initiators

are currently connected.

Connected

An initiator is connected to the target.

Offline

The target is not accepting connections.

iSCSI ACL

The iSCSI access control list (ACL) allows you to configure a LUN masking policy for each connected iSCSI

initiator. A LUN masking policy determines which LUNs the initiator is able to see and access. If no policy is

specified for an iSCSI initiator, then QTS applies the default policy to it.

Tip

• The default policy gives all iSCSI initiators full read/write access to all LUNs.

• You can edit the default policy so that all LUNs are either read-only or not visible to all

iSCSI initiators, except for initiators with specific permissions from a policy.

Adding an iSCSI LUN Masking Policy

1. Go to iSCSI & Fibre Channel > iSCSI > iSCSI Storage .

2. Click iSCSI ACL.

The iSCSI ACL window opens.

3. Click Add a Policy.

The name must consist of 1 to 32 characters from any of the following groups:

• Letters: a-z, A-Z

• Numbers: 0-9

• Special characters: Hyphen (-), space ( ), underscore (_)

5. Specify the initiator IQN.

6. Configure the access permissions for each LUN.
