Have just upgraded VC to 2.5 and now 4 of my 13 Farms have this error. Haven't upgraded the ESX hosts yet - these are still running 3.0.2. Other than the VC upgrade nothing has changed. Anyone have any pointers as to why the upgrade has now thrown up this problem when it has been an issue before ?

Hi.

Try to REеnable HA.

First uncheck Enable VMware HA -> OK

Than check Enable VMware HA -> OK

Thanks for the suggestion but I have already tried that to no avail !

I can lose the warning simply by checking the Allow VMs to be powered on even if they violate availability constraints but I don't understand why it's now an issue with VC 2.5 when with 2.0.2 there was no problem.

thanks

Gary

VMware HA enforces failover capacity by using memory & CPU reservations

to estimate the number of VMs able to recover from multiple host failures (VMware HA: Overview & Technical Best Practices)

How many hosts in your cluster and how many host failures allowed?

Is it possible that resource capacity of your three hosts really cann't satisfy sufficient number of resources all running VM's, if one host fail?

I guess it is possible and VC 2.0.2 overlooked certain conditions maybe. I've been doing some comparisons between some Farms I still have running on 2.0.2 and then some Farms running ESX 3.5.0 on VC 2.5.0 and see some differences on Resource Allocation so I think I'm going to get these particular Farms upgraded to 3.5 and see what, if anything, that changes.....

I upgraded VC from 2.0.1 to 2.5.0 with 3.0.1 ESX hosts. Both of my HA clusters are giving the same symptoms as above: Insufficient resources to satisfy HA. I did not have any warnings while on 2.0.1. Support simply says I don't have enough resources. Any updates on this?

Hi

Please describe your HA configuration.

We have 2 HA clusters:

1. 2 Dell PE2850's with 12gb and 8gb of RAM with 17 VM's.

2. 4 Dell PE6850's with 32gb of RAM each with 70+ VM's.

Before the upgrade, our 6850 cluster showed failover capacity for 2 hosts. Now it shows 0. I'm interested to know if this will "correct" itself after upgrading the hosts to 3.5.

I have configuration cluster 2 esx 3.02 hosts and vc 2.5 and no problem.

Capacity of 0 hosts mean your cluster is not worked properly.

Try to REеnable HA.

First uncheck Enable VMware HA -> OK

Than check Enable VMware HA -> OK

also

try to restart vmware management service from host console.

service mgmt-vmware restart

I've already tried both solutions on both clusters with no success.

The "problem" is that HA admission control got more conservative in VC 2.5 (see my comments in this thread http://communities.vmware.com/message/822784). If you have vms with different number of cpus in the same cluster (eg. some with 1 cpu and some with 2 cpus) then that will make the admission control overly conservative to ensure that there is enough unfragmented resources for all vms in the cluster in the case of a failover.
