I have tweaked my powershell script for the SCCM Dell/HP tags due to popular demand so that it can be run on a single machine using a list of service tags as the source and then will output to a CSV file. The source CSV can have any number of columns however it MUST have the following three for the script to work “Name,Vendor,Tag” in its default state. You also need to edit the $infile & $outfile variables as required.

Yet another role added to my Job description, Now I am managing our Virtual Servers. So true to form I’ve dived headfirst into powershell / powercli to see what I can do.

Overview and installing the operating system

Intro:

To facilitate testing of our software and so that support can model possible customer environments I was tasked with setting up a cluster with infiniband. I was excited as the system was a Dell PowerEdge blade cluster (our 1st blade system) and we have never used or deployed infiniband (this would be our 1st infiniband system), in fact other than a basic “we have heard of this and know (very) roughly what it is” no-one in the group had any real knowledge of it. After a few hours of searching the deepest recesses of the Internet I had a limited understanding of how to setup the system. I know how irritating it is to have to read the crud in order to find that wee gem of info so from here on I’ll mark the paragraphs of the article so those of you wanting to “just get it done” can skip them.
