VMM Create Cluster Error 25325

Issue

When trying to create an eight node S2D cluster in VMM 2016, the task fails with the following error:

“Error (25325): The cluster creation failed because of the following error: An error occurred while performing the operation.”

SCVMMError25325

Below is the PowerShell script used to create the cluster:

$AdminRunAsAccount = Get-SCRunAsAccount -Name ‘SVC_SCVMMAdmin’

$jobGroup = (New-Guid).Guid

$VMHosts = @()
$VMHosts += Get-SCVMHost | Where-Object {$_.Name -eq ‘x500s2d1.x500.local’}
$VMHosts += Get-SCVMHost | Where-Object {$_.Name -eq ‘x500s2d2.x500.local’}
$VMHosts += Get-SCVMHost | Where-Object {$_.Name -eq ‘x500s2d3.x500.local’}
$VMHosts += Get-SCVMHost | Where-Object {$_.Name -eq ‘x500s2d4.x500.local’}
$VMHosts += Get-SCVMHost | Where-Object {$_.Name -eq ‘x500s2d5.x500.local’}
$VMHosts += Get-SCVMHost | Where-Object {$_.Name -eq ‘x500s2d6.x500.local’}
$VMHosts += Get-SCVMHost | Where-Object {$_.Name -eq ‘x500s2d7.x500.local’}
$VMHosts += Get-SCVMHost | Where-Object {$_.Name -eq ‘x500s2d8.x500.local’}

$StaticIPAddress = @(“10.99.1.100”)

Install-SCVMHostCluster -ClusterName “MSC-S2D-A” -JobGroup $jobGroup -RunAsynchronously -EnableS2D -VMHost $VMHosts -ClusterIPAddress $StaticIPAddress -Credential $AdminRunAsAccount

Investigation

  • Cluster validation is successful (no errors or warnings at all).
  • VMM 2016 is running on Windows Server 2016 Datacenter (Build 14393), as are the S2D hosts.
  • VMM is on the same domain as the S2D hosts.
  • The S2D hosts are all in the same host group.
  • The Run As account in VMM has admin permissions on the S2D hosts and has Create Computer objects & Read All Properties permissions on the appropriate OU where the cluster account will be created.

Resolution

After many hours lost trying, I gave up on the VMM method of creating the S2D cluster, and created it as below from one of the S2D hosts.

New-Cluster -Name MSC-S2D-A -Node X500S2D1, X500S2D2, X500S2D3, X500S2D4, X500S2D5, X500S2D6, X500S2D7, X500S2D8 -StaticAddress 10.99.1.100 -NoStorage

Then:

Enable-ClusterS2D -PoolFriendlyName S2DPoolA -Autoconfig:$true

The cluster appeared in VMM, and S2D is fully manageable from VMM (e.g. managing the storage pool, creating cluster shared volumes, setting storage QoS policies, etc).
