The Cluster Remediation Options Report window contains a table with name of the cluster, host, or virtual machine on which an issue is reported, as well as recommendations on how to fix the issue.

You can generate a cluster remediation report when you create a remediation task for hosts that are contained in a cluster. You generate the report from the Cluster Remediation Options page of the Remediate wizard.

Details

A CD/DVD drive is attached.

Disconnect the CD/DVD drive.

Any CD/DVD drives or removable devices connected to the virtual machines on a host might prevent the host from entering maintenance mode. When you start a remediation operation, the hosts with virtual machines to which removable devices are connected are not remediated.

A floppy drive is attached.

Disconnect the floppy drive.

Any floppy drives or removable devices connected to the virtual machines on a host might prevent the host from entering maintenance mode. When you start a remediation operation, the hosts with virtual machines to which removable devices are connected are not remediated.

HA admission control prevents migration of the virtual machine.

Disable HA admission control.

HA admission control prevents migration of the virtual machines with vMotion and the hosts cannot enter maintenance mode. Disable HA admission control on a cluster to make sure that remediation is successful.

DPM is enabled on the cluster.

Disable DPM on the cluster.

DPM might put hosts into standby mode before or during remediation and Update Manager cannot remediate them. Disable DPM on a cluster to ensure that the remediation process is successful.

EVC is disabled on the cluster.

Enable EVC on the cluster.

EVC helps ensure vMotion compatibility between hosts in a cluster. When enabled on compatible hosts, EVC ensures that all hosts in a cluster present a common set of CPU features to virtual machines. EVC must be enabled so that the virtual machines are migrated successfully within the cluster during remediation.

DRS is disabled on the cluster. This prevents migration of the virtual machines.

Enable DRS on the cluster.

DRS enables vCenter Server to automatically place and migrate virtual machines on hosts to attain the best use of cluster resources.

FT is enabled for a VM on a host in the cluster. FT prevents successful remediation.

Disable FT on the virtual machine.

If FT is enabled on for any of the virtual machines on a host, Update Manager does not remediate that host.
