VMWARE Host issues
Hi Experts,
I have installed a new datastore from NETAPP ans changed the hosts from my old VSA to a regular cluster mode with 3 ESXi 5.5 hosts.
When I select a host in the summary I have some issues, see the picture.
Can you help me to fix it ?

ok done.
But no change.
I have a vswitch for the NFS connection to the storage, this is 10G connection.
Can I put the vmotion and management traffic also on it ?

To be honest i'm not quite sure if this will work. Don't try testing this in production but try to find what HA options you were using. This normally should be in the logging somewhere. Was your old datastore one of the HA targets? And yes you can put the other traffic on it also. The heartbeat is nothing more and nothing less than a constant ping to see if all devices that are needed for HA are available.

The old datastore was a VSA with 2 nodes.
Seems as if you HA configuration went wrong there.. I would try to reconfigure HA alltogether (if you actually use it, otherwise disable the entire feature).
ASKER
ok now I fixed the vmoition part.
This is working now and I tested it.

About the HA thing, some of my vswitches just have one nic connected.
Is this the case maybe ?

VMotion is somehting different than HA. With VMotion you can manually actively move VM's from 1 physical machine to another physical machine (ESX machine off course). HA does this for you when one out of 2 servers has an issue. So being able to vmotion is good and normally HA should then be functioning also.. But do you still get the error??
ASKER
Yes. Now I have the same warning on all hosts.

I found this on VM KB:
This issue occurs if there is no redundancy in shared storage to allow for datastore heartbeating. As of vSphere 5.0, vSphere HA requires a minimum of two shared datastores shared between all hosts in a cluster for proper datastore heartbeat detection to function.

Hey,
As said, it seems as if the datastore you created isn't accesible by all hosts. Please make it either accessible by both hosts or disable the message if you don't need HA.
Here is a link on how to disable.

Hi,
I think you have to look at this setting in your vcenter (vsphere client, not web) :
edit cluster setting (right click on cluster and select edit settings) / vSphere HA / Datastore heartbeating
And check the actual setting and preference.
At least do you have several datastores appearing here or only one?

some hosts just have one nic, is this a problem ?
ASKER
when I switch off HA, then the warnings are gone....
...but I need HA.
I just have one data-store and this data-store is connected to each host and accessible by each host.
What can I do here ?

I have already RE-ENABLED the HA feature.
No change.
I will check your article.

Hey Andrew, your articles are very useful. Thanks.
This is exactly my problem.
First I will install and configure the redundant nics.
Then I will create a datastore just for my ISO files which I need to install OS or software.

True HA is for redundancy so I'd follow the best practices, you'll thank yourself in the end.

ok thats it.
I have added a second datastore just for ISOS.
And the message is gone.

Strange thing is that this normally would have nothing to do with adding a datastore.
Could you try to Right click the hosts and run "Reconfigure for HA".??
