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.

 

 

List of Private Cloud related Hotfixes – 2016-02-03

I’ve posted my list of resources for finding Hotfixes previously here.  And this is a list of hotfixes we’ve imported in our WSUS server for our and our customers Private Clouds.
I usually want to install a hotfix to avoid getting a known problem, than try to find a solution to a problem after it has already happened and affected the users and customers.

wsus3

I’ve used the script I posted here to make the list. I’m sorry for the format below, but there is no good way to extract the info from WSUS and as I don’t really know if anyone is interested in this besides myself, I won’t spend hours on fixing a nice output right now or I would never get this blogpost published.  Sorry!

I’m using the MUUri to paste into the WSUS IE to search and locate the hotfixes fast, instead of manually search for each. There is unfortunately no way to script the import according to Microsoft PM’s, so it has to be done manually. Sigh…

Export information from WSUS about Hotfixes or Updates

I want to export information about all our Hotfixes in our WSUS Server, to share with the community as it’s sometimes hard to find up to date info of which hotfixes to apply in an environment.

Here is a quick and dirty script. No, scratch that, it’s not quick in any way but very dirty. The problem is that the WSUS Database does not contain the Description or Title of a Hotfix, so it’s not possible to export that info. Thus, I’ve to use a scripted Internet Explorer, to navigate to the URL of each Hotfix and grab the Title. Which makes the process veeeeeeery slow but I’ve been unable to come up with any better solution than that.

This is how the output looks like:

wsus2

And here is the full script, I will be really grateful if you share any changes you do as I’m sure there is a lot of ways to improve this script.

 

Geek Week – Building Datacenter and Private Cloud

Yours truly and @mikael_nystrom  are teaching a 5 day training called “Geek Week – Building Datacenter and Private Cloud“.
It’s a quite cool concept, where we are always at least 2 teachers (Mike and me, and sometimes members from our team) with a lot of real-life experience, teaching students how to build a Software Defined Private Cloud/Datacenter on Microsoft Technology in just 5 days. We have been doing this training about 4 times so far and each time got top score !

The training is covering things like; Software Defined Storage, Networking Compute, Bare Metal Deployment, SCVMM, SCOM, SCOR, Powershell(!), Azure Pack, Backup/Restore, Operational Insight, AD Design for your Fabric, GPO’s, Patch Management and a lot more!

So instead of just learning one product, you will learn the full stack, the concept, how to design, build and of course manage it.

We’ve made a short promo video with details here:

You will of course also keep the Lab Server and all the scripts!
We are both staying at the same hotel as the students, so you will have – almost 24h access to our knowledge, experience and brains during breakfast, daytime and in the bar in the evenings, Sunday-Friday.

We have delivered the training only in Sweden so far, due to the huge hardware requirements,  but have had participants from several other countries, including students from US (and doing the training in English than).

Unfortunately, for you but great for us, the next training in October, is SOLD OUT!
The next opportunity will probably be in February or March in Sweden, so talk to your manager and sign up while there are seats left.

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.

URL Rewrite (redirect) of HTTP to HTTPS with Powershell script

When deploying Web Application Proxy as a frontend to for example ADFS and Windows Azure Pack, or other services, the current version of Web AppProxy only supports HTTPS urls. It’s possible to use the “URL Rewrite” module for IIS to redirect users from HTTP to HTTPS. There are plenty of guides on internet on how to do that.
But I wanted to add that configuration to my WebApplication Proxy configuration script, and couldn’t find any powershell examples, so here is the script I’ve made.

It will use Web Platform installer to install the URL Rewrite module, then add the IIS Web Management tools, and in the end create a Global Rule redirecting all HTTP requests to HTTPS without the user noticing it.

 

 

VM Usage History fixed in UR7

I just noticed that the VM Usage History has been fixed in UR7. It’s been broken as long as I remember and used to only show the last 3 days of data, even if you selected 1 month. I don’t think it was mentioned in the ChangeLog for UR7?

AZ1Yay!

Uninstall old SCDPM Agents with Powershell on all Servers

When you want to add a server to Microsoft Data Protection manager to be managed (backup), it might already contain an old DPM Agent, which prevents the installation from going through. SCDPM will tell you to manually use Add/Remove Programs on each server and uninstall the old agent.

To find all servers in the environment with an old SCDPM Version run this script;

Of course, update the Version number to the latest current version of SCDPM Agent if it’s newer than 4.2.1338.0.
The get-adcomputer command will find all servers that are not disabled or Cluster Objects. So it should only give you the “real” servernames.
And here is a script that will uninstall all old versions of SCDPM Agent on all servers in the environment, so you can add the server through the SCDPM Management Console and get the new agent installed automatically.

Once again, change Version (4.2.1338.0) to the correct version you want to keep. It will uninstall all older versions.

Yay! You can now add the servers to SCDPM Successfully.

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/
