MSI Error 25543 when installing SPF Update Rollup

When trying to install an Update Rollup for SPF through Windows Update you may run into a Failed installation. And running the update manually gives a MSI Error 25543 where you have to click the Ok button like 10 times before it abort.

I’ve solved that at three different occasions by just stopping the IIS “Internet Information Services” and then installing the update manually.

Remember to start IIS after the update is installed and verify the bindings for SPF is still correct (there has been occasions where there have been duplicate bindings).

 

Potential version mismatch between WAP and SPF, please verify both component’s versions and if they’re compatible

I had a customer today who were getting errors when trying to create Virtual Machines in Windows Azure Pack (WAP).

WAP Tenant Log file
WAP Tenant Log file

Looking in the logfile on the Tenant server (Tenant Admin Log) showed that there were quite a lot of Error Events when a user is trying to create a server.

Some operations worked, like creating a virtual network but not deploying a virtual machine.

The interesting part here is the reference to; “Potential version mismatch between WAP and SPF, please verify both component’s versions and if they’re compatible”

Full Eventlog details, might help with search indexes.

 

I had a look at the SPF Server, and immediately noticed that the version of SPF was System Center 2016 RTM with no updates installed.

Updating SPF to the same version as Virtual Machine Manager (VMM) 2016 and Windows Azure Pack solved the problem.

Should the image contain hotfixes or not?

One more post in my WSUS/Hotfix series of blogposts. I’ve been asked a couple of times how we approve Hotfixes and if we include them in the images.

I’ve made an Autoapproval Rule where we approve all Hotfixes automatically to the various Computer Groups with a Deadline, like this.

wsus16

And this is how the details looks like;

wsus17

First of all, any server that could cause problems if it automatically rebooted doesn’t have a Deadline, thats servers like Hyper-V Hosts and SOFS Nodes. Those servers are managed by SCVMM’s (System Center Virtual Machine Manager) Patch Management. VMM has a feature to put a cluser node in maintenance mode, automatically drain the node of VM’s, patch it, and then bring the node back online again before it takes the next node.  So we handle all patching of clustered servers from SCVMM. While we let the WSUS Client handle all other servers. We might add SCCM to the mix some day and let it handle all of the servers, but as most of our customers don’t want to run SCCM to manage their Fabric, this is the way we do it now.

By putting a deadline, we know the hotfix will be installed sooner or later. And if there is a Patch Tuesday before that date, it will also install the hotfixes at the same time.

Notice that the hotfix is NOT approved for All Computers and NOT for Unassigned Computers. How come?

When we build a VM image for any OS, it’s done automatically through MDT. Those VM’s are ending up in Unassigned Computers as they don’t have a role yet and we don’t want any Hotfixes in the images. Of course, if there is a mandatory hotfix whish is needed to make the image or deploy it, that one will be included!

The reasons we don’t want any hotfixes in an image is quite simple if you think about it. There are two main reasons really.
The first one is that if we make an image in august, which contains hotfixes. When we deploy that image 3 months later, there is a big chance that the hotfix we had in the image is replaced by a proper update from Microsoft so there was no use for the hotfix in the first place.
Second, when we create an image, we don’t add Clustering, Hyper-V and other roles and features to the image, right? So Windows will then only install the hotfixes for the core OS. And when the image is later deployed and someone adds the Hyper-V Role, it would install hotfixes for that role then. So the server wouldn’t be fully patched anyway so adding 5 or 15 hotfixes automatically after deployment doesn’t really make much of a difference.
Third, a minor reason is also that we normally use the same images for Fabric, Workload and Tenants and we like to keep them quite generic.

Here is a great blogpost about making reference images from my colleague Mikael Nystrom.

 

Live (VSM) migration fails with mirror operation failed and access is denied error

When doing a Live Migration from SCVMM (System Center Virtual Machine Manager) with VSM, moving a Virtual Machine from one Cluster to another Cluster and at the same time also to a new Storage Location, you are getting an error message similar to this:

The strange thing is that there is a destination folder in the new location, it’s just does not copy content to that folder and aborts with the Access Denied error. But If you shutdown the VM first, so it’ s just a migration over the Network, it works!

The solution is to give the SOURCE Cluster Write Access on the DESTINATION Storage. When you do a VSM Migration, the destination Hyper-V host, creates the Directory on the SOFS Node, but it’s the Hyper-V Host that owns the VM that copies the VHD’s files to the destination storage. And as the current owner, by default does not have access to write there, it will fail. One could think that VMM should grant permissions to a host when VMM knows that the host needs to write in the location?

Maybe it’s fixed in the next version, but until then, there are two ways to do this.
Solution 1) In VMM add the Destination SOFS Shares as Storage on the Source VM Hosts like this. That will make VMM add the VM Hosts with Modify Permissions in the SOFS Shares so it can write there.

sofs2

This works quite fine, if the Hyper-V Clusters and all Storage is located in roughly the same location. But if you have one compute cluster with storage in one location, and another compute cluster with storage in another location. There is then a risk that you may be running VM’s cross the WAN link.

Solution 2) This is the one we used. By not using VMM to grant permissions to the shares, but rather do it manually we achieve the same solution as above but with the added benefit that a new VM will always be provisioned on the local storage and there is no (or a lot less) risk of running a VM cross the WAN link. Yes, it’s still technically possible to do it, but no one will by accident provision a VM that uses storage in the other datacenter.

You can either add each node manually, so we have created a “Domain Servers Hyper-V Hosts” security Group in AD where we add ALL Hyper-V hosts to during deployment. And then added that group to the Share and NTFS Permissions. All Hyper-V hosts will then automatically have write access to all locations they may need.

I wrote these two short scripts to query the VMM Database for the available SOFS Nodes and use powershell to grant permissions to the share, and to NTFS.

As all our SOFS Shares were called vDiskXX or CSVXX (where XX is a number) I just used a vDisk* and CSV* to do the change on all those shares. You might have to modify it a little to suit your name standard.

Updated Script (2016-02-04):
I got a report that the script was getting an error on some servers, which I managed to reproduce. Here is an alternative version where it will connect to the server and execute the ACL change locally via invoke-command. It’s also only changing permissions on Continuously Available (SOFS) shares.

 

 

Script to change from Dynamic to Static MAC Address on all VMs

A customer had a lot of VM’s with Dynamic MAC address, rather than the preferred method of using Static MAC addresses.
Here is a small powershell script that will shutdown each of the VM’s with a Dynamic MAC Address, change to a Static MAC Address and then start the VM.
I’m running the script on the System Center Virtual Machine Manager (SCVMM) Server and to make sure VMM does not shutdown itself, I’ve added an exclude for the SCVMM Server.

The MACAddress 00:00:00:00:00:00 will automatically be transformed into a real static address from VMM’s mac address pool.

Automatically Assign Availability Set Names to VMs with Powershell

This blog-post is about using System Center Virtual Machine Manager (SCVMM) Availability Sets to spread similar VM’s to different Hyper-V Hosts to increase reliability both when using Failover Clustering, and when using stand-alone Hyper-V hosts.

First of all, what is Availability Sets?
In SCVMM 2012 SP1, Microsoft added Availability Sets. Failover Cluster Manager users are probably familiar with AntiAffinityClassNames, and Availability Sets are a very similar concept. This allow the user to specify a set of VMs which they would prefer to keep on separate hosts, and the Intelligent Placement engine works hard to make sure that all our features respect that preference.

Attempting to place multiple VMs with the same Availability Set onto a single host will generate a placement warning, meaning that the host will be prioritized last in the placement dialog

  • When placing a VM with an Availability Set into a cloud placement or as part of a service will avoid hosts with another VM from the same Availability Set, and warn the user if that was the only choice.
  • Dynamic Optimization will never move 2 VMs from the same Availability Set onto the same host. It will also actively attempt to separate any VMs with the same Availability Set that are on the same host.
  • Power Optimization will never power off a host that would lead to 2 VMs with the same Availability Set sharing a host.
  • Putting a host in maintenance mode will attempt to spread VMs with the same availability set to different target hosts.
  • If your VMs are highly available and hosted on a Hyper-V failover cluster, VMM will create AntiAffinityClassNames on the VMs with an Availability Set, so that even during cluster failover, SCVMM opt to failover to different hosts, if possible.

You can manually create ASCVMM2vailability Sets through SCVMM by selecting Properties on a VM.
Just click Create to make a new Name and assign it to the VM’s you want to keep on separate Hosts. When a Availability Set is not assigned to a VM any longer, the Availability Set will be deleted automatically, thus cleaning up the list for you.

For example, for your SQL Server Cluster, you may want to create a Availability Set name called SQL and assign it to your SQL Server Nodes. Easy!
Also, if you are using Service Templates, you can opt in to automatically create Availability Set names for your services.

Though I like to control things like SCVMM1that automatically. Depending on your naming convention for your Virtual Servers, this might or might not be possible for you.
In our case we have a strict naming policy to name servers with:
PREFIX FUNCTION NUMBER as seen in this picture:

Which makes it very easy for me to define that all servers called CLAZSQ* are similar and should be kept on different servers.

But, if all servers were called SRV0001-SRV9999 it would not be possible to utilize the ServerName for setting Availability Set names, and you would have to query the CMDB for info first.

Also, in our environment we have multiple Tenants, who could each have servers called DomainController01 and DomainController02. So just having a availability set called DomainController, would not be enough. I have to make it DomainController_TenantName or something similar.

I wrote this quick and short Powershell script to automatically assign a Availability Set to all VM’s. It will remove Numbers from the VM Name, and use the VMName + UserID (Tenant Subscription id) as the Availability Set Name. Clean, simple and easy, just schedule it to run regularly, or even make a SMA Job to trigger when a VM is created through AzurePack.

And then trigger an Host Cluster Optimization of all Clusters in the Environment if you don’t want to wait for the normal one.

 

 

Update SCVMM Agent with Powershell

I just updated our System Center Virtual Machine Manager 2012 R2 Environment to Update Release 7. SCVMM would then report that the SCVMM Managed Computers has an Out-of-Date Agent which need to be upgraded.

It’s possible to do it manually by right clicking on each server and choose “Update Agent” or use this short powershell script to do it on all machines at the same time.

It will Update the Agent on all Managed Servers for you (no restart needed in my case).

 

 

Microsoft Fabric (datacenter and private cloud) related Hotfixes

Here is the list of Hotfixes I’m deploying in our production environment and that I deploy regularly at customers. Those production environments are a Fabric (Private Cloud) running Hyper-V, Storage Spaces, SOFS, ADFS, Domain Controllers, Azure Pack, System Center, SQL Servers, and more, yes everything you need in a Fabric. Though not Exchange, Lync or Sharepoint etc. So this list might not be complete for your system.
And as always, use your own judgement which hotfixes you would like to deploy in your environment or not. Hotfixes are not tested as much as ServicePacks used to be, and Update Rollups are, so it’s possible there are problems with them.

My philosophy is that I like to have everything updated and reduce the risk of having a problem. The number of times I have had issues with a hotfix are, as far as I can remember one (1), including the several years I worked at Microsoft Premier support and were assisting customers with problems and now and then provided a hotfix for an issue. So I rather install hotfixes I know of and are relevant to reduce the risk of hitting a real problem than wait for that issue to actually happen and then find a hotfix or open a case with Microsoft.

A hotfix included all previous fixes for that module too, so when troubleshooting a problem, it’s common that Microsoft Support asks you to install hotfix X, Y and Z to get the components involved in the problem to the latest revision. Thus, it might look like some of the KB Articles and hotfixes below does not apply to you, or you don’t have that problem in your environment. But if it’s related to Cluster, Hyper-V or any other component that you do use, it might be wise to install it anyway as it could fix 10 other problems that you are not aware of.

I’ll always import the updates directly into WSUS and deploy them, so I can use approval rules and see reporting of which updates has been installed where. Here is a good guide for how to do it; http://www.thirdtier.net/2013/03/how-to-manually-add-a-hotfix-to-wsus/

There is as far as I know (and I’ve also asked Premier Support) no way to script the import of updates into WSUS directly from Windows Catalog. You will have to manually use a Web Browser to import them. Click, Click, Click, wait, Click, Click….

The list is ordered by release date so the latest hotfixes are at the top. And looking at a fresh Fabric deployment, it looks like most hotfixes older than 10/14/2014 has been superseded, except for KB2965733 which was still needed by a couple of servers in this new fresh environment. But things might be different for you. wsus1

I’ve also written a Powershell Script for SCVMM to create Baselines and import all Updates and Hotfixes there. So it’s easy to use compliance scans and use remediation from SCVMM to keep the Fabric updated.
You can find it here; https://gallery.technet.microsoft.com/scriptcenter/SCVMM-Automatic-Baseline-8779597b

It’s not that easy to find new hotfixes or to know which ones are mandatory. Luckily, there is a blogpost to help you out. I’ve collected all sources from Microsoft product teams, where they list the hotfixes they recommend.
You can find the lists here: http://www.isolation.se/list-of-resources-to-find-hotfixes-and-updates-for-windows-server-2012-r2/
