Can anyone assist in a powershell scripts to

list the hosts in a cluster and identify which ones are primary and which ones are secondary nodes ??

Are you talking about a VI Toolkit version of cat /var/log/vmware/aam/aam_config_util_listnodes.log

There is nothing in the SDK objects that shows which node is primary/secondary.

But I was looking at using psexec to execute the ftcli command on a cluster node.

That lists the nodes.

I was thinking the same thing when I saw the article on yellow-bricks about primary nodes for blades.

How to do it with Powershell.

I've been searching for this myself but it's not in the SDK unfortunately,

Nope, the only solution I came up with is to use plink, launch the ftcli command, capture and analyse the output with PowerShell.

What is do to get ouput of the plink command is use teh | out-string method.

When i call a plink command like:

$STRCMD1 = $PLINK + " " + $USER + " " + "-pw" + " " + $PASSWORD + " " + $ESXHOST + " df -h"
$CHECKFS = invoke-expression $STRCMD1 | out-string

You can then use the output again in your powershell script.

Very intresting article .. Identifying a single point of failure !!!!

At the moment we are having to read the logs and joggle the servers into maintance mode daily to get the primary nodes spilt across two Chasis.

The Option for 8 servers in a cluster is not a solution for us as we will be losing overhead resources...

Does anyone know if the number of allowed primary node would be increased in ESX4???

Looks like we need to move this thread to another forum???
