HA Disabled

  • 1.  HA Disabled

    Hi,

    I have created a new vCentre 4.1 environment running 2 x 4.1 ESXi servers, I have turned on HA and DRS however I get the following error

    Failed to increase memory reservation and limit for host /vim/vmvisor from 1232 to 1381. HA may not configure on the host

    On the summary tab on each host it tells me HA is disabled.

    I don't remember setting any reservations or limits as this is a default install so any help would be welcome!

    Thanks

    Do you have any virtual machine in this cluster?

    Yes, I have 13 VM's running inside the cluster

    Hi

    Can you try to vmotion 1 or 2 machines from the affected host to another host in the cluster and reconfigure HA? See what happens.

    Look CPU and Memory resource reservation and limit for every virtual machine, maybe you overlook and give to much reservation or limit to one or more virtual machines. Use PowerGui software....it's a nice tool for such a things.

    Hi,

    I can't migrate any VM from 1 host to another, when I try to migrate I get the error in the first attachment. I have checked through the settings on all my VM's and they are all setup the same way in terms of CPU and memory reservation - again I have attached a screen shoot. All VM's were built from a 2008R2 template which had a very straight forward config no CPU or memory reservations were configured.

    Thanks

    Ok, switch off the HA and then try to migrate a VM. What happens?

    If I turn off HA I can successfully migrate my VM's

    Ok, than you actually have problem with memory host/vim system resource pool. See my link in previous reply and set memory to unlimited and than turn on HA and try it again.

    Did you check ntp settings on both esx hosts? I had the similar problem when HA didn't work because ESX hosts had different time. My error wasn't the same as your but you never known :smileyhappy:.

    Have you tried to turn HA after that? Did you get the same error?

    Hi,

    Thanks for the suggestion however I have applied that fix to both my ESXi host's - the first time it didn't take the change however after applying it the second time I have my memory set to Unlimited - however it fails with almost the same error

    A general system error
    occurred: Failed to
    increase memory
    reservation and limit
    for host/vim/vmvisor
    from -1 to 148. HA
    may not configure on
    the host.

    Thanks
