Dear;

Hi have the message:

The computer object associated with the cluster network name resource 'Cluster Name'

could not be updated in domain 'xxx.xxx.xxx.xxx.xxx' during the

Password change operation.

The text for the associated error code is: The specified network password is not correct.

The cluster identity 'CLPWGIRSQL$' may lack permissions required to update the object.

Please work with your domain administrator to ensure that the cluster identity can update computer objects in the domain.

Please tell me what I need to check

Thank you so much!!!.

Hello Lucas Peñaloza,

I wanted to follow up to see if you successfully completed the upgrade of the final node (PWGIRSQL1) and failing back your resources.

To summarize our last discussion regarding your final step:

The Risk: Update-ClusterFunctionalLevel is irreversible, but it is safe as long as all nodes are online, running the new OS, and you have passed the Test-Cluster validation.

The Strategy: There is no rush. You can leave the cluster in "Mixed Mode" for a few days to verify stability before running the command to lock in the new features.

If your cluster is now fully upgraded and stable, please consider accepting the answer as it helps other people sharing the same question benefit too. Thank you!

Hi Lucas Peñaloza,

You are definitely correct to be cautious about High Availability (HA). While a Windows Cluster can technically run with one node on a new OS and two on the old OS (Mixed Mode), your approach minimizes risk significantly.

By updating both Secondary nodes (PWGIRSQL2 and PWGIRSQL3) before you ever touch the Primary (PWGIRSQL1), you ensure that when you finally perform the failover:

  1. Stability: You are failing over to a new OS node (PWGIRSQL2) that already has another new OS partner (PWGIRSQL3) ready to sync.
  2. Redundancy: If something goes wrong with PWGIRSQL2 immediately after the upgrade, you have PWGIRSQL3 (also upgraded) as a safety net.

The Approved Execution Order:

  1. Update PWGIRSQL2 (OS + SQL).
    • Result: Node 2 is healthy and syncing again.
  2. Update PWGIRSQL3 (OS + SQL).
    • Result: Node 3 is healthy and syncing again.
    • State: Now you have 2 upgraded nodes waiting in the wings.
  3. Failover the Availability Group from Node 1 to Node 2.
    • Result: Your Production is now running on the New OS.
  4. Update PWGIRSQL1 (The old Primary).

This is the safest, most professional way to execute a 3-node cluster upgrade. Proceed with confidence.

I hope you've found something useful here. If it helps you get more insight into the issue, it's appreciated to accept the answer. Should you have more questions, feel free to leave a message. Have a nice day!

YES, absolutely. You must always begin your upgrade process with the Secondary Replicas. Since your cluster is now healthy, the safest rolling upgrade workflow is to upgrade the passive nodes first, leaving the active Primary (PWGIRSQL1) untouched until the very end to keep your application online.

Here is the recommended sequence:

Phase 1: Upgrade the Secondary (PWGIRSQL2)

Since PWGIRSQL2 is already a Secondary replica and you just stabilized it, it is the perfect candidate to start with.

  1. Backup: Take a full backup of your databases on the Primary (PWGIRSQL1) just in case.
  2. Suspend Data Movement (Optional but Recommended): In SSMS, you can temporarily suspend data movement for the PWGIRSQL2 replica if the upgrade will take a long time (to prevent the transaction log on the Primary from growing too large while waiting).
  3. Perform the Upgrade: Apply your Operating System updates or SQL Server patches/upgrades on PWGIRSQL2.
  4. Reboot & Validate: Restart PWGIRSQL2. Once it is back online, open SSMS on the Primary and verify that PWGIRSQL2 returns to the Synchronized (or Synchronizing) state. Phase 2: Upgrade the Next Secondary (PWGIRSQL3)

Once Node 2 is green and fully synced, repeat the process for PWGIRSQL3.

Phase 3: The Failover (Switch Roles)

Once both Secondaries (Node 2 and Node 3) are upgraded and healthy:

  1. Change the Availability Mode of PWGIRSQL2 to Synchronous Commit (if it isn't already).
  2. Perform a Manual Failover of the Availability Group from PWGIRSQL1 to PWGIRSQL2.
    • Now PWGIRSQL2 is the Primary and is running the new version.
  3. Verify applications are connecting successfully. Phase 4: Upgrade the Old Primary (PWGIRSQL1)

Now that PWGIRSQL1 is a passive Secondary, you can safely proceed to upgrade it.

    Vphan,

            Look

    PS C:> Install-WindowsFeature -Name Failover-Clustering -IncludeManagementTools

    Success Restart Needed Exit Code Feature Result

    True No Success {Remote Server Administration Tools, Failo...

    And;

    User's image

    User's image

    Cluster network interface 'PWGIRSQL2 - Ethernet1' for cluster node 'PWGIRSQL2' on network 'Cluster Network 2' failed. Run the Validate a Configuration wizard to check your network configuration. If the condition persists, check for hardware or software errors related to the network adapter. Also check for failures in any other network components to which the node is connected such as hubs, switches, or bridges.

    PWGIRSQL2, has 2 NICs

    Ethernet1, is the Backup Net.

    I believe the mistake is irrelevant, no

    Hi Lucas,

    First, this is actually great news regarding the SIDs. I have reviewed your screenshots, and I can confirm your environment is now safe from the "Identity Crisis":

    PWGIRSQL1: SID ends in ...1738-500.

    PWGIRSQL2: SID ends in ...2762-500.

    PWGIRSQL3: SID ends in ...6669-500.

    You have successfully achieved unique identities for all three nodes. The root cause of your original cluster failure is gone.

    Now, regarding the installation hang on PWGIRSQL2, dont worry. This is a very common side effect of a fresh Sysprep or Domain Join. The Server Manager GUI often hangs because the background "Windows Modules Installer" service is either waiting on a generic Windows Update check (which might time out if the server has no internet) or is blocked by a pending reboot flag left over from the domain join.

    To unstick the Installation:

    1. Force a Reboot Since the GUI is stuck, you cant cancel it gracefully.

    Close the "Add Roles and Features Wizard" (use Task Manager to kill it if necessary).

    Reboot PWGIRSQL2 immediately. This will clear the locked files and reset the TrustedInstaller service.

    1. Install via PowerShell: Once the server is back online, dont use the GUI Wizard, it hides the actual errors. Use PowerShell, which is faster and provides real-time feedback.

    Open PowerShell as Administrator on PWGIRSQL2. Run the following command:

    Install-WindowsFeature -Name Failover-Clustering -IncludeManagementTools

    1. What if it hangs again? If the PowerShell command hangs at "10%" or "24%", it means the server is trying to download source files from Windows Update and failing.

    => You need to mount the Windows Server ISO (the installation media) to the server (e.g., as drive D:).

    Run the command specifying the local source:

    Install-WindowsFeature -Name Failover-Clustering -IncludeManagementTools -Source D:\sources\sxs

    Once the feature shows Success: True in PowerShell, you are ready to add the node to the cluster.

    I hope you've found something useful here. If it helps you get more insight into the issue, it's appreciated to accept the answer then. Should you have more questions, feel free to leave a message. Have a nice day!
