Hi all,
I have 3 hosts running ESXi 5.5. I manage these hosts from a vCenter server.
I have created a cluster out of these hosts and enabled HA on the cluster. There are no error messages or no warnings. The vSphere HA summary page of the cluster shows:
In addition to this, I have management network redundancy on each host via VDSwitch. There is portgroup called mgmt, which is for management network, this portgroup is connected to 3 NIC uplinks (Fibre A, Fibre B and Copper) for redundancy. Another portgroup I have is vMotion. Both mgmt and vMotion portgroups have correct vLans:
Now I have found two problems:
1. When I disabled the port connected to vmnic5Uplink from the the Cisco switch, the host goes down; meaning there is no management network redundancy although I am using all 3 available NICs for management traffic. Nowhere in vSphere does it mention there is a problem with management redundancy or any warnings regarding that. Only when I disabled ports connected to any of the 3 uplinks, the host goes entirely down (Not responding).
2. When the host goes down, HA does not work. HA tries to migrate VMs residing in the affected host but HA migration fails. Before the host becomes "not responding" stage, there is this error:
After about 10 seconds of this error message, it says
I cannot figure out why this is happening. Anyone has any ideas from looking at the above?
Thanks
