VMware: The number of heartbeat datastores for host is 0

May 7th, 2013 2 comments

Today I added some vSphere 5.0 u1 hosts in a new created cluster, the SAN will be delivered next week so I didn’t have central storage, to finish my new cluster setup I configured HA and DRS. After configuring HA I received this warning message:


The number of heartbeat datastores for host is 0, which is less than required: 2




To (temporary (until the SAN is installed)) hide the warning message I configured the HA – Advanced Option:

  1. Log in to vCenter Server
  2. Right-click the cluster and click Edit Settings
  3. Click VMware HA > Advanced Options
  4. Under Option, add an entry for das.ignoreInsufficientHbDatastore
  5. Under Value, type: true
