Splunk Certified User

August 28, 2018 Leave a comment

A guy from one of the Facebook groups I’m in challenged everyone to take the free Splunk Fundamentals 1 course & take the certification test. Accepted & done! I must say, for a free course it was pretty good. Picked up a lot of good information. However, it looks like they are ending this course but a new track will be starting soon.

Cisco Certified Network Associate Cyber Ops (CCNA Cyber Ops)

I’ve been working on the Cisco CCNA Cyber Ops certification since December 2017. I was very fortunate to have been invited & accepted into the “Cisco Global Cyber Ops Scholarship Program“. Cisco invested $10 million in this program to increase the pool of talent in the cyber-security field; one that we as Americans really need to focus on. It was fast paced & exciting. Now on to the next one…

Error Installing HP iLO Firmware Upgrade

March 30, 2018 Leave a comment

When trying to install a firmware update for the HP Integrated Lights-Out 3 (iLO) you receive an error that says, “The software will not be installed on this system because the required hardware is not present in the system or the software/firmware doesn’t apply to this system.”

Looking in Device Manager, there is a device called Base System Device under Other devices.

Looking at the properties of Base System Device, the Device status says, “The drivers for this device are not installed. (Code 28).” On the Details tab the Hardware Ids property shows a value of PCI\VEN_103C&DEV_3307&SUBSYS_3309103C&REV_04.

The mystery device is the iLO 3 (CHIF). As of the date of this post, the latest version of the iLO 3/4 Channel Interface driver is 3.30.0.0. https://support.hpe.com/hpsc/swd/public/detail?swItemId=MTX_e74f93921947408eb5de783d27

The installation is pretty quick & in my case did not require a reboot. Below are screenshots from the installation.

Next, install the iLO 3/4 Management Controller. As of the date of this post, the latest version is also 3.30.0.0.

https://support.hpe.com/hpsc/swd/public/detail?swItemId=MTX_e196fcb67e1941de959751786f

Just like the interface controller, the installation is pretty quick & in my case did not require a reboot. Below are screenshots from the installation.

Now try the iLO firmware upgrade & it will work. Below are screenshots from the installation.

Hyper-V host blue screens (BSOD) after being added to SCVMM

February 26, 2018 Leave a comment

Description

When rebooting a Hyper-V host running on VMware Workstation after adding it to System Center Virtual Machine Manager (SCVMM), the host will not boot & blue screens (BSOD).

Cause

When a Hyper-V host is added to SCVMM, several hardware IDs are added to the Multi path I/O (MPIO) list. One of these hardware IDs are not compatible on VMware Workstation.

Information
To see a list of hardware IDs added by SCVMM run:

Get-MSDSMSupportedHW

It’s worth noting that when the MPIO role is installed, the only ID in the list is a generic entry for Vendor 8 Product 16.

Solution

Boot the Hyper-V host to the last known good configuration. Once it’s back up, add the Hyper-V host to SCVMM again. Before rebooting, remove the MPIO entry for MSFT2011SASBusType_0xA by running the following PowerShell command:

Remove-MSDSMSupportedHW -VendorId "MSFT2011" -ProductId "SASBusType_0xA"

Now reboot the Hyper-V host.

Nested VM Performance is Slow

August 27, 2017 2 comments

This is taking forever!

That’s what I was thinking when deploying nested virtual machines on vSphere 6.5 in my lab (OK, it’s my laptop). The configuration was simple enough; the latest version of VMware Workstation, an ESXi host VM, & a Windows Server 2012 R2 VM nested in ESXi. Simple enough, right?

Watching the console of the nested VM I notice it seemed…slow. When the VMware logo on the POST screen finally appeared I could see the screen painting making it look like an 80’s arcade game.

As you can see that took way too long. So with Process Monitor running on the laptop I power on the VM again. After it runs for about a minute the fun task of sifting through the ProcMon log begins. If you’ve ever used ProcMon you know it’s more of an art than a science. The first thing I always do is use the analysis tools from the menu.

Honestly, I just go through each of them & see if something jumps out at me. Real technical, I know. In all the sifting & sorting one thing that kept jumping out was the Anti-Virus software.

This wouldn’t be the first time an Anti-Virus product interfered with an application working properly so I started digging through the AV interface. After clicking around for a bit I come across some very interesting settings.

“Enable hardware-assisted virtualization” & “Use nested virtualization where available”. Those look promising. I uncheck both of those settings & give the laptop a reboot. This time when the nested VM boots it POPS!

According to Avast’s website, the software is supposed to detect that virtualization applications like VMware Workstation or Microsoft Hyper-V are installed & automatically disable these settings.

Cheers!

Quick Post: Windows Update Error 80073712

March 17, 2017 Leave a comment

When installing a Windows Update, you receive an Error Code 80073712.

According to https://support.microsoft.com/en-us/kb/947821, 80073712 is ERROR_SXS_COMPONENT_STORE_CORRUPT The component store is in an inconsistent state.

From KB947821 I downloaded & ran the tool for my version of Windows. It can take a while.

When it was finished, I checked C:\Windows\Logs\CBS\CheckSUR.log. It found one error.

Doing a Bing search for part of the bad manifest, I was able to determine it was KB3150513. I manually downloaded the update from the Microsoft Update Catalog (http://catalog.update.microsoft.com/v7/site/Search.aspx?q=KB3150513) then installed it on the computer. No more error!

Side note:

I didn’t have to do this but may have to also reset the Windows Update Components (https://support.microsoft.com/en-us/kb/971058)
