RecoverPoint is one of my favourite products. It’s unique, reliable and has helped me out of trouble on more than one occasion. Whilst most VM admins associate it with SRM and thus Site/LUN/Datastore recovery, it can also fill in an often overlooked gap in data protection. Pre and Post backup Continue Reading

Back to basics – Hot add new disk to Linux VM
I recently showed this to a colleague who is new to Linux. It should be part of your minimum capabilities as an admin. Manipulating disks/volumes on a guest VM is a task we all have to do. In this post I’m going to detail how to add a new disk to Continue Reading
vSphere/ESXi: When good tasks go bad – Fix with ESXCLI via PowerCLI
Most of the time, tasks we start in vSphere just work. That’s why we love it. Queue ’em up, and move onto something else. Sometimes though, they go bad. They freeze, stick, die or just plain error out. This happened to me last week. After changing the scratch location for Continue Reading

VMware PowerCLI – Suppress vCenter Certificate warnings
A very quick post this one, but an annoying thing I often see left unchecked in environments, that is simple to fix in a minute. Yes, this is an old topic, but it’s still too evident today…. This should be in your “just do it” category. It’s the awful Certificate Continue Reading
PowerCLI – What went where ?
I had a nice little episode with a set of PSOD looping hosts in December which resulted in a lot of guests getting moved around automatically during attempted HA recoveries. This got me thinking about all the automation that goes on ‘behind the scenes’ as a result of DRS and HA. Continue Reading
Auto ESXi Host Configuration Backups with PowerCLI
Regularly throughout the year, I like to take PIT (Point in Time) backups of my ESXi host configurations. These form part of my Critical Config backups that I hope I’ll never have to use. But like any backup, these are merely another safety net as we strive to have more Continue Reading
