Hi, I'm new in this platform and I installed Vphere 4.1, my environment is:
1 Storage
3 host
1 Vcenter with Datacenter created
The problem is in the HA apparently, I configured HA and now test my environment before going to productive.
I configured all vswitch with 2 nics, both to 1GB.
Today I change the cable of one nic of the HOST 1 and the VM in host 1 continuous running OK, but when I reconnect the cable in the nic, the VMWARE POWER OFF my VM and restarted in the same HOST 1.
Why occurs this if my second nic of host 1 never lost connection?
is this correct or my vm never has power off?
Sorry by my english is not very good.
Regards.
How are you secondary nics setup in your vSwitch? Standby, Active, etc.
Unless you configured something special, there may only be two reasons for this:
The 30 sec are best practice and may be adjusted for your needs. Default setting is 15000 (15 sec).

Hi, thanks for response.
My 2 nics are in active mode in the vswitch.
The 2 nics are connected to the same switch Cisco 3750, but I not configured nothing with spanning-tree portfast
maybe this is a my problem.
Now, if I have another switch and I connect 1 nic connect to the cisco 3750 (1) and the another nic 2 connect to the cisco 3750 (2), I need spanning-tree portfast?
Do I have the same a problem?
Sorry for my unknowledge
Regards.
You'll have to configure spanning-tree portfast on each switch port, no matter if it is on the same switch or another. Unless you set it, the spanning-tree protocol can take up to ~45 seconds to allow traffic on a port in case of an uplink failure. Since HA is triggered after 15 seconds (by default) you would always run into HA once an uplink fails.

Hi Andre, thank you for your recommendation.
