iSCSI software initiator node naming standards

While it is possible to rename iSCSI software initiator nodes on a SnapDrive for Windows host, Data ONTAP requires standard iSCSI software initiator node names.

When you install the Microsoft iSCSI Software Initiator, an applet is installed that enables you to rename the initiator node to something other than the standard iSCSI qualified name (IQN) or IEEE EUI-64 (EUI) formats. Data ONTAP, however, does not recognize non-standard initiator node names and will return an error when you attempt to create a LUN using a node name that does not use the IQN or EUI formats.

The following are the formats for standard initiator node names.

IQN-type node name uses the following format:

iqn.yyyy-mm.reverse_domain_name:any

The EUI-type node name format consists of the “eui.” prefix, followed by 16 ASCII-encoded hexidecimal characters.

Note: A dash (-) is allowed in the IQN name; however, an underscore (_) is not allowed.

IQN-type node name example

iqn.1991-05.com.microsoft:winclient1

EUI-type node name example

eui.02004567A425678D
