SnapReminder sends e-mails to owners of snapshots
I love this script from Alan Renouf:-
[F]ind the offending snapshot, find the person who created it, get their email address from AD and send them an email reminding them of their mortal sin.
Our IndependentNonPersistent drives here prevent us from using snapshots, but I’m working on a “utilisation checking” script, that should help us cull some neglected machines and I might integrate some of Al’s AD interrogation into that.
VMware Developer CodeCentral
VMware have launched a new community site for code examples, and there’s a section on VMware vSphere PowerCLI (formerly VI Toolkit).
They seem to be picking the best scripts from the regular contributors to the forums, so it’s a good place to have a look for examples. They’re rated by users, and tend to be slightly better documented than the ones posted in the forums (which tend to be appended and amended as the thread progresses).
I/O Queues, “micro-bursting”, and Multipathing
Virtual Geek has an interesting article on VMware I/O queues, “micro-bursting”, and multipathing.
Looks intimidating at first glance, but it’s suprisingly straightforward.
