I don’t know if anyone else has had this problem with ESXi 5.0.0 but I am having an issue where the event logs are showing that connection to a Thecus NAS device is dropping every 5 seconds to every 5 minutes.
The VMX configuration files int he inventory change to ‘Unknown’ and then roughly around 10 seconds later they come back. The VM 99% of the time doesnt turn off but I have known it to.
The way that the standalone ESXi server is set up in this configration has worked perfectly with previous versions and I can only put down this ‘latency’ message to fcat that I have installed or upgraded I should say to ESXi 5.
The server has 2 NICs that were teamed to host all the VMs on a 10.0.x.x range with the NAS device also on the same range presenting the storage via iSCSI. I know that VMware recommend that the storage be presented on a separate IP range but this has worked before.
I have now tried having 1 NIC set up for ISCSI vmkernel and 1 for VM Network and binding the sofware iSCSI adapter to the vmkernel port for iSCSI but no luck. Next is to add an ip range for iSCSI after that I’m stuck and it will be a fresh install of ESXi 4.1.0 which I know works. The only issue I might have is that I’ve already formatted the LUN that stores the VMs as VMFS v5 😦
