Fast publish (this is becoming a common phrase) so be kind…
When refreshing host cluster in VMM, for some reason we started to see the below error in VMM:
Error (25122)
The specified address ((AllocatedIPAddressData#e449) { id = 6ea8ddba-b8a7-43f6-856e-0a4d35076681, LastUpdatedTimestamp = 3/24/2015 5:55:17 AM }) is already allocated by the pool (IPPool-LNet-Mgmt). This address should be assigned to only a single entity.
Recommended Action
Resolve to which entity this address is allocated.
The script to fix it.
# Ok, let’s find the problematic IP:
$ID = "6ea8ddba-b8a7-43f6-856e-0a4d35076681"
$IP = Get-SCIPAddress | where {$_.ID -eq $ID}
# OK, so we have the IP as a variable… Now let’s revoke it:
Get-SCIPAddress -IPAddress $IP | Revoke-SCIPAddress
# Let’s get the host cluster that failed into a variable.
$VMHostCluster = Get-SCVMHostCluster -Name ""
# Get the IPPool from the IP Pool Name in the error
$IPPoolName = "IPPool-LNet-Mgmt"
$IPPool = Get-SCStaticIPAddressPool -Name $IPPoolName
# Assign the IP to the cluster:
Grant-SCIPAddress -GrantToObjectType HostCluster -GrantToObjectID $VMHostCluster.ID -IPAddress $IP.Name -StaticIPAddressPool $IPPool -Description $VMHostCluster.Name
