Trouble Setting Up VMWare HA
So, my goal with this project is to set up a simple VMWare HA Cluster. I am currently getting an error in Virtual Center on one of the hosts I have placed in my cluster (it has a small red triangle and exclamation mark) and in the event log says "Failed to Resolve Short Name [Name] to IP Address on Host [Public IP]" I did make an attempt to set up a Virtual Machine, but, when I did that it seems as though the Virtual Machine is not able to establish an Internet connection. I think something is wrong with my Networking setup.
Here is the description of my setup:
1. For my shared array, I am using an EMC Clariion AX150i (iSCSI)
2. The storage array is connected to two separate switches, one for network 10.100.0.x and one for network 10.101.0.x
3. Each host in my cluster is able to connect to the virtual drive on the disk array, and is already formatted with VMFS
4. I have the following network setup for each host in VMWare:
a: vswitch0
a(i): VM Network
a(ii) Service Console ([Public IP])
b:vswitch1 (Note, this adapter is connected to a crossover cable, which is connected to by other ESX Host)
b(i): VMKernel: 10.102.0.2 *Also configured as my VMotion adaptor/virtual switch
c:vswitch2
c(i) Vkernel2 (10.101.0.12)
c(ii) Service Console 2 (10.101.0.14)
d:vswitch3
d(i) Vkernel3 (10.100.0.12)
d(ii) Service Console 3 (10.100.0.14)
Please, please help me try to understand what I did wrong here and how to fix it. I have been looking at this for a long time and am a bit frustrated, and really need some help. I do not have a lot of experience with VMWare, and really want to get this working. Please, Please!
Thanks in advance!

All of the DNS Settings on the service console of vswitch0 seem proper (small letters, right dc's, right gatways, etc.)
ASKER
It seems as though the DNS entries have not been created (e.g. the computer settings have not been established in my DC/Active Directory).
Below is the hosts file that is currently installed on server 1:
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
[public ip 1] name1.nod.com name1
Here is the hosts file that is currently installed on server 2:
Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
[public ip 2] name2.nod.com name2
I assume what you are suggesting is to copy name2 to the server 1 file, and name 1 to the server 2 file (e.g. copy entries from one file to another? If I do that do I need to restart the ESX Servers?
Please let me know

Ok! I made that entry, and now I have no more red x next to my cluster. :-) :-) However, I still have the issue with the virtual machine, as it seems as though that vm cannot access the network. Additionally though I should mention that when I look at the 'map' diagram from my VM it shows both of the IP addresses from either cluster host with big red x's in front of them. On the virtual machine, I am still unable to ping anything (e.g. www.google.com) even though the network.interfaces on the virtual machine looks fine.
ASKER
Just another quick update: I changed the network on the virtual guest to 'Virtual Machine Network'. Now on my map I have one host with a green dot, and one with a red x (instead of two red x's). However, I still am unable to ping anything (e.g. www.google.com) from the virtual guest itself. I think this is the last bit to figure out, and then I'm finally done! Please help!

The issue that I had was related to two things (1) configuration of the Service Console gateway; and (2) configuration of my virtual switches. HeinoSkov's answer definately got me pointed in the right direction, and I owe him a LOT of thanks!
