About iSNS service version incompatibility

The specification for the iSNS service is still in draft form. Some draft versions are different enough to prevent the storage system from registering with the iSNS server. Because the protocol does not provide version information to the draft level, iSNS servers and storage systems cannot negotiate the draft level being used.

In Data ONTAP 7.1 and after, the default iSNS version is draft 22. This draft is also used by Microsoft iSNS server 3.0.

Note: When you upgrade to a new version of Data ONTAP, the existing value for the iscsi.isns.rev option is maintained. This reduces the risk of a draft version problem when upgrading.
