Cisco UCS PowerTools and PowerShell
As I mentioned in a previous post, we are upgrading our infrastructure and we are using Dell EMC VxBlock. So far this upgrade is going fairly smooth, but we are still at the very beginning of the process. So once I found out that the VxBlock was configured to contain UCS hardware, I began looking to see what Cisco had to offer for PowerShell modules to help manage the new hardware that we are getting. … Continue reading

PowerCLI to get Virtual to Physical CPU Ratio
I was in a meeting today, and was asked, “What is the current virtual to physical CPU ratio?” I didn’t have an answer for this question, so I asked PowerCLI for the answer.

This will be a handy script that can be ran rather quickly. … Continue reading
What’s your (host)name?
While digging through Log Insight on a problem, I found a new one. A large majority of VMhosts were not configured with a proper hostname.

Trying to get a log file off a machine that doesn’t allow for the drivers to install becomes when trying to research the issue. … Continue reading
PowerCLI to Change Default Multipathing Policy
As it would seem in my environment the default multipathing policy changes with the seasons. We have become very accustom to making these changes based on the newest whitepaper from the storage vendor.
To change the default multipathing policy, you will need to know the name of the Storage Array Type Plugin (SATP) that you need to change the Native Multi-Pathing (NMP) policy for.… Continue reading
