QTS 5 / QuTS hero 5

In QTS/QuTS Hero version 5, the iSCSI feature Service Binding has been renamed to Network Portal Binding. This feature has also been upgraded with new security features and support for virtual LANs. For this reason, if you downgrade a NAS from QTS/QuTS Hero version 5 to QTS/QuTS Hero version 4, Service Binding will be reset and iSCSI initiators might lose access to NAS services.

To work around this issue, after downgrading QTS or QuTS hero you must reconfigure iSCSI Service Binding:

1. Go to Control Panel > Network & File Services > Network Access > Service Binding.

2. Select Enable Service Binding.

3. Under iSCSI Service, select one or more network interfaces.

Important

• By default, QTS/QuTS hero services are available on all iSCSI interfaces.

• Services must be bound to at least one interface.
