HA error – Could not reach isolation address

March 10th, 2010 | 54 Comments | Posted in VMware

I get this error message: “Could not reach isolation address: none specified” on one VMware VSphere host.  The error message only appear on one host. HA on the other hosts works normal.  I tried to run the “Reconfigure HA” on that host, the same error keep appear.   I also tried to disable HA for the cluster dan re-enabled it but no success.

After googled and searched, I found the source of the problem.  The default gateway on the Service Console was missing.   Not sure how this could happen.  After fill in the default gateway IP and run the Reconfigure HA, the HA works fine on that host.
