What happens if HA has failed?
Environment: Two ESX3.5 hosts in a cluster, Vcenter server is a machine virtual itself on a single host. The two hosts connected to the SAN.
Say, if a host is gone, and HA na not kick in for any reason, then the VMs on the failed host was not stopped gracefully or still alive, but not accessible from the network.
1 & gt; Restarting the virtual machines on the virtual machines failed on another host?
2 & gt; What kind of challege can I met?
I just want to be prepared for the worst. Thanks in advance.
Hello
When VC starts and HA is enabled it goes out and checks the State of each virtual computer power. If the virtual machine is running nothing happens. If turned off, nothing happens as well.
HA handles this at the time of the event. So if VC is a virtual machine and the host dies, it will start VC on the other host. Now if VC does not start, then it is still not a problem that VC will simply get the State of the virtual machines, and not necessarily to start all VMs.
If HA fails however, you need to determine why, make sure there is no split-brained VMs (IE running on the two hosts), etc. I would create a document DR/Business COntinuity that covers all cases. VMware HA failing is just one case.
