Get HP Disk+Array Health from ESXi

David Ligeret wrote a Python script for monitoring the status of a server running ESXi. We are running ESXi on HP hardware and his script wouldn’t catch the disk or array failures. So the attached script is my updated version that will catch the HealthState codes from the HP hardware.

Apply Driver Package – Operation failed with 0x80070002

I’ve been using SCCM coupled with the HP Insight Control Suite to deploy our server images on bare-metal HP servers and blades. Recently, I have been working to deploy Windows Server 2008 R2. If you get the message “[Windows Package Manager] Operation failed with 0x80070002; The system cannot find the file specified”, this is caused by using an older/wrong version of a boot image. I installed the latest WAIK, re-configured the winpe.wim, imported and redistributed the new boot.wim, and finally pointed my Task Sequence to use the new boot image.

Here is a walkthrough from technet on how to update the boot image to add needed drivers and packages.

Welcome

Greetings! My name is Branden and I will be posting about various technologies and solutions to the day-to-day issues I come across. Every so often I have a I.T. related problem and cannot find a solution online. I will try to post my solution here for your benefit.

From time to time I will post about random other subjects and post some of my photos.
