Default Isolation Address

If a host thinks it is isolated by default it will ping its gateway.  It is best practice to have more than one isolation address, and you can have up to 10 of these.  Duncan Epping has a good article on it here.  Here is a simple script I found somewhere on the web.

$cluster = Get-Cluster -Name ITN

New-AdvancedSetting -Entity $cluster -Type ClusterHA -Name ‘das.isolationaddress1’ -Value 1.2.3.4

New-AdvancedSetting -Entity $cluster -Type ClusterHA -Name ‘das.usedefaultisolationaddress’ -Value false

#Disable and reenable HA

Set-Cluster -Cluster $cluster -HAEnabled:$false

Set-Cluster -Cluster $cluster -HAEnabled:$true
