Specify the name of the new target portal group. You can use up to 32 characters for the target portal group name.
A target portal group is a group of one or more network interfaces over which the filer receives iSCSI requests. The network interfaces in a target portal group collectively coordinate an iSCSI session. All TCP connections within an iSCSI session must use interfaces assigned to the same target portal group. Each interface can be assigned to one and only one target portal group.
Once you create a target portal group, you cannot change its name.
