rdm

Introduction Just a quick post to say I’ve written a couple of powershell functions to deal with Raw Device Mappings and perennial reservations within a vSphere environment. Although I do try to avoid them, some customers do still have RDMs in their environment, mostly for Microsoft failover clusters configured at the virtual machine layer. Some ad-hoc scripts exist for this at the moment, but I wanted to break out the ‘getting’ of RDMs and then setting them to perennially reserved.
