How to set the NoMonitor registry key on a clustered Enterprise Vault(EV) Server.

Description

After adding the NoMonitor registry key as per the Registry Values on a clustered EV Server when the resouces are offline, the key will be deleted when the EV cluster resources are brought back online.  Ensure the Enterprise Vault Services clustered resources are online when the changes are made.

Details of the NoMonitor registry key is included below.

Note: Please reference the following article to have the EV Admin service not monitor specific drive letters only for clusters. See https://www.veritas.com/docs/000005206 for details.

Warning: Incorrect use of the Windows registry editor may prevent the operating system from functioning properly. Great care should be taken when making changes to a Windows registry. Registry modifications should only be carried-out by persons experienced in the use of the registry editor application. It is recommended that a complete backup of the registry and workstation be made prior to making any registry changes.

EV will not shut down the services immediately, there is a 1-3 minute window for the Administrator to add in the NoMonitor registry key on the primary node of the EV cluster before the EV Admin service checks disk space.

Steps to implement the NoMonitor or DiskMap registry keys on a clustered EV server:

1. Ensure all EV cluster resources are online.

2. Add the NoMonitor or DiskMap registry key.

     a. Add a DWORD key named NoMonitor. Set to 1. (This will stop the EV Admin service from monitoring all disks on the EV server. Setting this key to 0 means the EV Admin service will continue monitoring all local disks.)

3. Take the EV cluster resources offline.

4. Bring the EV cluster resources back online and confirm the registry key is still in place.

5. Fail over to any other node, the NoMonitor or DiskMap registry key should be transferred to that node as the EV cluster resources come online.
