I’ve run into an issue lately in my VMware environment that really frustrated me because I didn’t understand why it was happening, and because there wasn’t an obvious way of determining that it wouldn’t happen again. The problem I’d been having was mismatched UUIDs on NFS datastores on clustered hosts. It’s a configuration issue that isn’t apparent until you need to vMotion a VM or are relying on HA/DRS.

As you may be aware, VMware Update Manager has functionality built-in that allows the VMware administrator to stage patches to hosts, for remediation at a later time. There are a number of downsides to the way this functionality is implemented in the VMware VUM GUI.

Automating VMware cluster remediation without DRS: PowerCLI
As you may be aware, VMware’s Update Manager (VUM) does a great job of remediating vSphere hosts when they’re in DRS-enabled clusters. You select the cluster you want to remediate, verify the correct baselines are attached, and click Remediate. VUM will automatically evacuate each host in turn, then patch, reboot, repeat as necessary until the entire cluster is remediated.

Setting up SFTP on Windows 2008
Recently, I had a task assigned to me to get SFTP up and running on a Windows 2008 server. I did some Googling and found a few resources, but only by combining the various bits of information was I able to get it up and running. I thought I’d throw it all together into a blog post, in the hopes that it will help someone else out.
ESXi 4.1 remote log collection with VMware vMA 4.1
When I first decided to blog about this, I started doing some Googling for resources. I ran across an excellent post by Simon Long that talked about using vMA’s vilogger capabilities for remote logging, but his blog post was written with 4.0 in mind, and didn’t line up exactly with how things are done with vMA 4.1. My goal here is not to reinvent the wheel with screenshots galore, but merely to document the basic steps and differences in the setup for vMA 4.1.
