Guest OS disk usage script revisited.

Guest OS disk usage script revisited.

I was recently asked to re-write my good ol’ script that retrieves disk usage from virtual machines and formats this information into nice’n’tidy CSV report.

When HA kicks (in) and you’re not quite ready…

When HA kicks (in) and you’re not quite ready…

vSphere HA functionality is definitely one of the top contributors to success of VMware virtualization. But have you ever been in a situation, when one of your vSphere hosts failed (say, in the night) and vSphere HA did its job perfectly, restarting all these 50 VMs affected, then you come to work (say, “a little late”) just to find the whole gang of application owners, process controllers, incident managers etc. gathered at...

Rolling restart of ESXi management agents using PowerCLI

Rolling restart of ESXi management agents using PowerCLI

Right after my (waaay too short) holidays finished I was faced with the issue described in this KB. Nothing really serious, but an annoyance, that everybody wants to get rid of as soon as possible. It didn’t take very long before I realized that (in my case) the only effective workaround was to perform “a rolling restart of management agents on affected hosts” (it was a whole 16 host cluster in my case). Of course I...
