Issue/Introduction

The cdm alarms for disk, from a MS Windows cluster, are asserted using the cluster IP address in "Device Name" instead of the active cluster hostname. Despite the annoying this is, it prevents the alarms from displaying correctly in Spectrum integration.

Strangely under Inventory view, the robots appears using the node hostname.

Cause

If the probe can not determine the hostname, then nas probe will try using nas Name Services.

This is explained in detail on next technical document.

Environment

Release : 20.3

Component : UIM - CLUSTER

Resolution

To make the alarm appears in OC with the active hostname node, instead of the cluster ip address, next steps are required:

1. Get the cluster hostname. You can do this from "Server Manager" Tools->"Failover Cluster Manager".

    Another option, is directly from the cluster probe Configure:

2. Configure the nas probe, and add the entry in Name Services Address Table. Lock the entry.

For instance:

3. Acknowledge the alarms that were asserted using the cluster ip address. When they be asserted the next time, they should come using the cluster node hostname.
