Deploy Centos 6 from VMWare Template

This is just a quick gotcha that I found ages ago then forgot about and then had to figure out again. Before you convert the VM to a template.

rm /etc/udev/rules.d/70-persistent-net.rules

sed -i ‘/HWADDR*/d’ /etc/sysconfig/network-scripts/ifcfg-eth0

sed -i ‘/UUID*/d’ /etc/sysconfig/network-scripts/ifcfg-eth0

 

Update:

This also applies to SLES 11 SP2 (use /etc/sysconfig/network/ifcfg-eth0)

 

 

Programs without MSI Product ID

Recently I had an issue where ActiveSetup wasn’t installing some applications when deployed. It turned out that it was due to some of the packaged applications not having a program with the Windows installer information populated. As it was believed that this may not an isolated issues I was tasked with producing a report of all Packages where the information was missing. This is not actually possible via the default reports as none of the views exposed to SCCM actually contain this information. The only way to get this information is to query the SCCM database table “PkgPrograms”, and to do that and have a permenant report SSRS is needed as it can run with the credentials of the user generating it or with an execution account which may have more access.

SCCM Patch Compliance Reports

Updated: 2013-11-20 – Fixes for rdl files and 2012 report, I’ve edited the RDLs but I have no infrastructure currently to test on so feedback is welcome.

I was watching SCCM Guru Episode 9 with Garth Jones, when I saw in his powerpoint presentation two reports for patch compliance that I liked the look of. So I decided to see if I could emulate the reports, I will say here having only seen the final product in his slide my reports will look similar to his, and may even share code, however I have not seen ANY of his code so any similarities here are purely coincidental and not me just copying his code and taking credit.

Task Sequence and Package Management Reports

There are 3 reports in this group;

The first returns a list of all packages in a Task Sequence and the DPs they are targeted at that are in a “not installed” state. Currently this only detects targeted and not installed, once I figure out the SQL i’ll update this so it includes DPs that it is not targeted at as well.

The second lists all Task Sequences that reference a specific package, the idea here is if you wish to replace a package with a newer version or decommission a package you can get a list of all of the TSes that include it.

The third and final report compares two Task Sequences and returns a list of packages that are in one but not the other along with the ID of the Task Sequence that it is in.

Software Distribution Reports

I have 85 or so DPs across more than 5 Primary sites and sometimes I see failures in newly created Task Sequences (or even old ones) during an OS deployment due to a package not being available.

  • Distribution status of a specific package on a specific distribution point – This report shows the installation status of a package on the specified distribution point.
  • Distribution points without a specific package – This report shows any Distribution Points a Package is not installed on. N.B. Package MUST be targeted to the site in order to be detected
  • Distribution points without a specific package in a site – This report shows any Distribution Points a Package is not installed on in the specified site. N.B. Package MUST be targeted to the site in order to be detected
  • Distribution status of a specific package in a site – This report shows the installation status of a package on each of its distribution points in the specified site

Deployment Management Report

Sorry it’s taken so long but here is my 1st post (of many) since my change of Job.

In my new environment machine history isn’t retained upon a machine rebuild, so how do I determine what a machine had before it was rebuilt? Well there is no “easy” answer to this, the company historically used a vbs script to diff the uninstall reg key against a list of standard or core applications. This worked to some extent but was far from perfect and could result in very large lists of applications that were not even installed by SCCM.

Network Diags

One of my users was complaining of “slow vm performance over the network”, so I requested a few simple diags including a traceroute from his machine to the vm instead I got a traceroute from the VM to the VM. So I decided that clearly I was asking too much from the user and threw the following batch file together (I may rewrite it in powershell for fun later).

Clone-VMFromSnapshot

This is a function that allows you to clone a VM from a specified snapshot. The only way to do this in the UI would be to take a snapshot of the current state, revert to the one you wish to clone, clone, revert to latest snapshot and then delete latest snapshot. As you can see that is time consuming and takes numerous mouse clicks.

I recommend adding this function to your powershell profile so you always have access to it.

As always feel free to comment.
