So apparently the output returned is in some sort of class of object that I am not referencing correctly. Google isn't helping with scripting examples, just setting via GUI.

Anyone got a pointer to teach me how to parse out what I need from this command?

What happens if you run this (I would check myself but we don’t use clusters):
(Get-CauClusterRole -Cluster PHAMSCLUST14).name.DaysOfWeek

It’s probably a hash table. But I also don’t have a cluster handy to check.

Pure guess:
$CAU = Get-CauClusterRole -Cluster PHAMSCLUST17
$CAU[ 'DaysOfWeek' ]

For giggles, I tried executing the splat and subsequent command. The blue information bar has the following while failing to connect to an actual cluster:
Setting properties for CAU clustered role on cluster "System.Collections.Hashtable"
Try the following:
$Parameters = @{
ClusterName = “YourClusterName”
DaysOfWeek = “YourDay”
WeeksOfMonth = “YourWeeksOfMonth”
RebootTimeoutMinutes = “YaKnowWhatToDoByNow”
Force = $true
}
$Result = Set-CauClusterRole @ Parameters
$Result.DaysOfWeek
Does this give you what you need?
Also, I’m surprised this won’t get you the info you need…
( Get-CauClusterRole -Cluster PHAMSCLUST14 ).DaysOfWeek
( Get-CauClusterRole -Cluster PHAMSCLUST14 ).WeeksOfMonth
At the very least it should return the values for those parameters for that cluster. As with others, I don’t have clusters so I cannot test that. However, I did test it with other commands using splats.
Later,

Formatting fail caused a space between ‘@’ and ‘Parameters’. There should be no space between those two.

Try something just a little different from what you’ve already done and send us the output:
$CAU = Get-CauClusterRole -Cluster PHAMSCLUST17
gm -I $CAU
This will prevent the array unrolling that I think happened in your initial posting.

Ok it’s just a simple array. So you have to iterate through it:
$CAU = Get-CauClusterRole -Cluster PHAMSCLUST17
foreach( $item in $CAU ) {
$item.Name + ' = ' + $item.Value
}
Not a very efficient implementation.
