VMM Error 25122 – Refresh Host Cluster

I received the error above while refreshing the cluster from VMM console and here is the full description “Error (25122) The specified address ‘(AllocatedIPAddressData#[7928d1]) { id = 9aa09df6-2cde-48ed-b4e2-6bbd48fb4e5b, LastUpdatedTimestamp = 11/25/2016 1:46:13 PM, objectType = AllocatedIPAddress, Enabled = True, Accessibility = Public, CreationTime = 11/25/2016 1:46:14 PM, modifiedTime = 11/25/2016 1:46:14 PM, GrantedToList = }’ is already allocated by the pool ‘IP Pool xy’. This address should be assigned to only a single entity. Recommended Action Resolve to which entity this address is allocated.

The reason for this error is that when I created the cluster  I used an IP for cluster management that was  part of the Management IP Pool . To avoid this error you have to reserve the IP  by going to Fabric > Logical Networks > Choose the Logical Network and Select the IP Pool > Properties and at the IP Address Range you have the option to reserve the IP address for other use.

Thanks to vNiklas I was able to clear the IP using the following Powershell commands:

$ID = “9aa09df6-2cde-48ed-b4e2-6bbd48fb4e5b”
$IP = Get-SCIPAddress | where {$_.ID -eq $ID}
Get-SCIPAddress -IPAddress $IP | Revoke-SCIPAddress

To make sure that the address was revoked you can run the following command which will display all the static IPs and to which Hosts/VMs are they assigned:

$IPPool = Get-SCStaticIPAddressPool –name “IP Pool xi”
Get-SCIPAddress –StaticIPAddressPool $IPPool
