For the project I’m doing now I had to add VMFS volumes to eight servers. Not that I’m lazy, but with a couple of ESX hosts and still adding volumes it kinda gets nasty to do a rescan on all systems. Thankfully I remembered a post by Eric Sloof about a plugin from Icomasoft to do a SCSI scan.

This really saved me a lot of work and irritation :)
