Users Guide

To receive periodic notification about the availability of latest version (RPM, OVF, RPM/OVF) of OMIVV, perform the following

steps to configure the latest version notification:

1. On the OMIVV home page, click Settings > Appliance Settings > Notifications > Latest Version Notification.

2. Select the Enable Latest Version Notification (Recommended) check box.

3. To receive the latest appliance version notification, select the day and time.

4. Click APPLY.

Configure deployment credentials

OMIVV acts as a provisioning server. The deployment credentials enable you to communicate with iDRAC that uses the OMIVV

plugin as a provisioning server in the auto discovery process. The deployment credentials enable you to set up iDRAC credentials

to communicate securely with a bare-metal server that is discovered using auto discovery until the OS deployment is complete.

After the OS deployment process is successfully complete, OMIVV changes the iDRAC credentials as provided in the host

credential profile. If you change the deployment credentials, all newly discovered systems using auto discovery are provisioned

with the new iDRAC credentials from that point onwards. However, the credentials on servers that are discovered before the

change of deployment credentials are not affected by this change.

1. On the OMIVV home page, click Settings > Deployment Credentials.

2. Enter the user name and password. The default user name is root and password is calvin.

Ensure that you provide only the iDRAC supported characters and iDRAC local credentials.

3. Click APPLY.

Hardware component redundancy health—Proactive

Proactive HA is a vCenter (vCenter 6.5 and later) feature that works with OMIVV. When you enable Proactive HA, the feature

safeguards your workloads by proactively taking measures based on degradation of redundancy health of supported components

in a host.

After assessing the redundancy health status of the supported host components, the OMIVV appliance updates the health

status change to the vCenter server. The available states of redundancy health status for the supported components (power

supply, fans, and IDSDM) are:

● Healthy (Information)—component operating normally

● Warning (Moderately degraded)—component has a noncritical error. The moderately degraded states are represented as

Warning in the Type column on the Events page.

● Critical (Severely degraded)—component has a critical failure.

NOTE:

An Unknown health status denotes the unavailability of any Proactive HA health update from the Dell Inc provider.

An unknown health status might occur when:

● All hosts that are added to a Proactive HA cluster may remain in the unknown state for a few minutes until OMIVV

initializes them with their appropriate states.

● A vCenter server restart may put the hosts in a Proactive HA cluster into an unknown state until OMIVV initializes them

with their appropriate states again.

When OMIVV detects a change in the redundancy health status of supported components (either through Traps or polling), the

health update notification for the component is sent to the vCenter server. Polling runs every hour, and it is available as a fail-

safe mechanism to cover the possibility of a Trap loss.

NOTE:

● When configuring events, it is recommended to select Post all Events option as event posting level. For more

information about configuring events, see Configure events and alarms on page 90.

● Proactive HA is available only on the platforms that support redundancy on power, fan, and IDSDM.

● Proactive HA feature is not supported for PSUs for which redundancy cannot be configured (for example, cabled PSUs).
