CommVault and VMware – VSA Backup Filtering options

     There’s always been a number of ways to apply filters to VM’s and disks. It could be done at the Backup-Set or Sub-client level. This is a little bit clunky and can lead to unnecessary VM’s being backed up.  If you’re using a Capacity based licence, this is Continue Reading

ESXi 5.5 – Automating VMFS UNMAP w/ PowerCLI and PowerShell

With vSphere 6.5 recently released, a nice feature was the automated execution of the UNMAP command against thin provisioned datastores to reclaim space.

VMware DRS rule manipulation using PowerCLI (EMC VPLEX use case) Part 1.

VPLEX is another of my favourite products,  and for good reason. I currently run a Metro cluster underneath a VMware platform that has proven to be super reliable.

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
