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
