# DasClusterIsolatedEvent

## Summary

All hosts were isolated from the network in a HA cluster.

## Causes

There is an issue with network redundancy configuration in the management network.

## Resolutions

Check the network configuration for proper network redundancy in the management network.

::: note

By default, the isolated host powers off its virtual machines. These virtual machines can then successfully fail over to other hosts in the cluster.
