HELP with Vsphere HA

[kfkehua]

We have a cluster with 2 ESX servers. with HA and DRS configured. when I shutdown one server, the virtual machines are not being restarted on the other server.

Am I missing anything? Any other configuration need to be made?

Please advise.

thx.

you may be violating failover constraints and therefore not failing over.

How many VM's total? What are the specs on the ESX Hosts (CPU, RAM)

[kfkehua]

no, no constraint violoation. 12gig per server, quad core nehalem. only deployed 2 VMs. one Vcenter and one testing VM.

[kfkehua]

here are my settings:

Enable Host monitoring - off

Admission Control - Allow VM to be powered on even if they violate availibility constraints

VM restart priority - High

Host isolation response - shutdown

Enable VM monitoring - off

[Troy_Clavell]

Enable Host monitoring - off

what happens if you check Enable Host Monitoring?

[bulletprooffool]

HA events will not kick in if host monitoring is disabled, You;ve basicaaly turned off the requests tio verify whether the host is up or down.

Question: do I have to do a "reconfigure Vmware HA" for the hosts after applying the changes to the HA cluster?

[Troy_Clavell]

anytime you make changes to your HA config, I would reconfigure. If that doesn't work, disable HA all together, then enable again with Host Monitoring.

[krowczynski]

You can try to do so.

Have you make any rules on your HA, is it configured "Fully Automated"?

What happend if you put one host into maintanace mode?

[kfkehua]

Solved.

i tried the host monitoring option before and it didn't help. so I thought it might be something else.

now i tried it again, but did a reconfigure HA for the hosts and it works.

stupid that it doesn't apply the changes automaitcally.

Thanks all.

[Troy_Clavell]

you have to reconfigure so the changes can be pushed down to the HA agents within ESX.

Glad to see you got it resolved. Please mark the thread as answered.
