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.
