Configure Proactive HA for Rack and Tower servers
Prerequisites
Ensure that all hosts are configured for redundancy of all the three supported redundant components (power supply, fans,
DIMM, and IDSDM).
Steps
1. Create a host credential profile and associate hosts to a host credential profile. See Create host credential profile on page 41.
2. Verify that hosts inventory is completed successfully. See View host inventory job on page 84.
3. Verify that the SNMP Trap destination in iDRAC is set as the OMIVV appliance IP address.
NOTE: Ensure to confirm the availability of a host for a Proactive HA cluster from the logs data.
4. Enable Proactive HA on a cluster. See Enabling Proactive HA on a cluster.
Configure Proactive HA for Modular servers
Prerequisites
Before configuring Proactive HA for the Modular servers, ensure that the following conditions are met:
All hosts are properly configured for redundancy of all the three supported redundant components (power supply, fans,
IDSDM, and DIMM).
Hosts and chassis inventory is completed successfully.
About this task
NOTE:
It is recommended that all the modular hosts in a Proactive HA cluster should not be in the same chassis, because
the chassis components (PSU and fan) failure affects all its associated servers.
Steps
1. Create a host credential profile and associate hosts with host credential profile. See Create host credential profile on page
41.
2. Verify that hosts inventory is completed successfully. See View host inventory job on page 84.
NOTE: Ensure to confirm the availability of a host for a Proactive HA cluster from the logs data.
3. Create a chassis credential profile for associated chassis. See Create chassis credential profile on page 46.
4. Verify that chassis inventory is completed successfully. See View chassis inventory job on page 86.
5. Launch CMC or OME-Modular and verify that the Trap destination for chassis is set as the OMIVV appliance IP address. For
more information about configuring trap, see the CMC and OME-Modular User's Guide available at https://www.dell.com/
support.
6. Enable Proactive HA on a cluster. See Enabling Proactive HA on a cluster.
Enable Proactive HA on clusters
Prerequisites
Before enabling Proactive HA on clusters, ensure that the following conditions are met:
A cluster with DRS enabled is created and configured in the vCenter console. To enable DRS on a cluster, see the VMware
Documentation.
All hosts that are part of the cluster should be part of a host credential profile and successfully inventoried.
For a modular server, the corresponding chassis must be added to the chassis credential profile and successfully inventoried.
Enable SNMP events on the iDRAC settings page for all the hosts present in the cluster.
Steps
1. In vSphere Client, expand Menu, and then select Hosts and Clusters.
All the hosts and clusters are displayed in the left pane.
