Symptoms

A Unity user is receiving the following error message in Unisphere on the DR site: The system is unable to detect an Ethernet port or link aggregation on which the NAS server network interface was configured. Switch the interface to use another Ethernet port or link aggregation. If this does not help, restart the management software. If the problem persists, contact your service provider.

Cause

There is no matching physical interface on the source for the specified NAS server. As a result, it cannot properly failover. Note the IPs are removed intentionally, however the key take is the Ethernet Port missing (dash)

Resolution

On the Destination Array for the affected NAS Server, open the NAS Server Properties.Choose the Network Tab and select the IP address assigned and choose Edit.In the Edit NAS Server Interface window that appears, select the Override IP checkbox, configure the same IP as the production NAS server on Different physical network or interface or specify a different IP with a different physical interface. Select the appropriate physical network interface of your choice. Screenshot of Override Address Checkbox activated. Note all IP addresses removed from the screenshot.
