Phillip,
This helps too.
So, no LPARs, OK, but virtual machines, right? I assume the VMs can run
Linux or Windows, or other OS's.
So would such a hierarchy be possible:
systems
├── CEC:0FF28
│ └── LPAR:VM23
│ └── zVM:VM23
│ └── virtualMachine:LNXADM32
│ └── Linux:admin32.example.com
└── IntelServer:serialNum
└── VMware:someID
└── virtualMachine:someID
└── Linux:hostname.example.com
Thanks.
-Mike
