VC can't connect to ESX host

Hi, I have few ESX hosts in my cluster that for some reason is not responding, so I restarted the service console, VC agent and vswif0. Still I can't connect to the ESX with VC. It still says the management services on the host are not responding.

any ideas?

Also, is there a command line to vmotion the servers off? The last option is reboot the host, but I want to vmotion them off if I can.

Thanks

what happens if you do a service mgmt-vmware status?

if it's running, try to restart it using service mgmt-vmware restart

if it's stopped try to start it using service mgmt-vmware start

Enable VMotion from the command-line

name resolution is setup properly? All hosts are added into vCenter with FQDN? you can ping both short name and FQDN from your vCenter Server?

DId you try to disconnect the host from vCenter and then connect again?

I had a similar issue awhile back, and the culprit wound up being that the Service Console was starved for memory. If you haven't already, I'd suggest bumping up SC memory above the 272 MB default setting. Unfortunately, this requires a reboot to take affect.

In the meantime, you may want to try connecting directly to the system with the VI client to see if that works. If this doesn't work, then I'd try disconnecting/removing/reconnecting in VC.

How's your process list look? Do you have a bunch of vpxa processes running?

Ok, got it resolved. The root cause is the my /Var/Core is full, and there is 0% free space. Once I cleared it out, restart the mgmt service and it worked. Thanks for all the help.
