Configure San Host Path Redundancy, Release 12.2.2

The following table provides an overview of the significant changes up to this current release. The table does not provide an exhaustive list of all changes or of the new features up to this release.

The SAN Host Path Redundancy check enables you to view the non-redundant host storage paths. It helps you identify the host enclosure errors along with the resolution to fix the errors.

All fabrics that are discovered must be licensed or this feature will be disabled in the Cisco Nexus Dashboard Fabric Controller Web Client. When the feature is disabled, a notification is displayed stating unlicensed fabrics are discovered.
Host Path Redundancy determines that the ports are part of the same enclosure by using the enclosure name displayed in NDFC. If the enclosure names are not exactly the same, then they will be viewed as separate devices. When the names are not exactly the same, the user must manually change the names in the edit enclosure dialog in NDFC, in order for Host Path Redundancy and other features to consider them the same device.
