VMware ESX Collection.
Handling pre-failure events is supported for virtual machines that are on shared storage.
Handling automatic pre-failure events
To handle automatic pre-failure events, perform the following:
1. Click Deploy
→Virtual Machine→Handle Virtual Machine Host Prefailure Events.
2. In Step 1, Select the target events, select the PreFailure Events collection that has been created, then
click Apply.

Handling automatic pre-failure events using the vCenter Server DRS cluster enabled
in the vCenter Server
Prerequisite: The ESX hosts must be in a cluster in VMware vCenter Server and DRS must be enabled on the
cluster.
To handle automatic pre-failure events using the vCenter Server DRS cluster enabled in the vCenter Server,
perform the following:
•
Create a collection in Systems Insight Manager containing the ESX hosts that are in the DRS enabled
cluster in vCenter.
•
Configure pre-failure handling using the steps mentioned in Handling automatic pre-failure events .
When the pre-failure events are generated on any system in the System Collection - Prefailure VMware
ESX Collection
, the VMware ESX host is placed in maintenance mode in VMware vCenter Server. VMware
vCenter Server then moves all the virtual machines hosted on this VMware ESX system onto other hosts
available in the VMware Cluster.
Handling semi-automatic pre-failure events with the vCenter Server DRS cluster enabled
in the vCenter Server
In the semi-automatic mode of event handling, verify the SMTP settings in the Options
→Events→Automatic
Event Handling
→Email Settings. When a pre-failure event occurs, you are notified through email. When
you receive the email, perform the following steps to handle the pre-failure events:
1. Select Deploy
