This is a quick one-liner to get the configured swap datastore on a host/hosts: If we want to make the name look a little nicer we could do: This would get the results for all the esxi hosts for the target that you are connected to, however if you wanted to reduce the scope to …
My role currently involves dealing with Windows in addition to the standard VMware/hardware infrastructure. If we ever thought that patching ESXi was fun, dealing with WSUS is whole other ball game. I will no doubt get around to writing a full post about it in the near future, as dealing with it has been quite …
Quick powershell snippet time ! When you have a UCS Central instance with a number of domains, knowing what free slots you have available is quite useful – especially when you’ve got a smart hands service and won’t be racking new servers but instead having to communicate instructions.

vSphere Replication is really a wonderful product – I’ve been using it for a few years now across a few employers and I’ve never had a really serious problem with it – it just seems to work. Sure, there are a few feature requests we could make of it, for example setting a schedule of …

I found this useful as when troubleshooting ESXi locks, the MAC address of the locking host is shown and sadly not the name. Once I had the name I was able to continue debugging my problem š Get-UCSCentralServiceProfile | …
From the first article we looked at how to use the SSH Sessions Powershell module to log into a Linux server that will, via a script, log into a Brocade FC switch and get the zoning configuration. As per the disclaimer in the first part, these articles have been assembled from my notes and memory …
I’ve been looking at automating physical server creation, and there are tools from Cisco and NetApp that allow Powershell to do the heavy lifting for UCS and Storage. The missing part of theĀ process is the FC switches (Brocade in this case, though when I researched this I could not find a toolkit for Cisco MDS) …
This is a quick snippet that allows you to retrieve UCS Blades that have SD cards – this might be useful in determining if your blades are ready to have an OS installed on them. These scripts assume you’ve already connected to your UCS Central or UCS Domain. This will get the blades if you’re …
