While poking around the ESX 3.0 service console last week, I came across the amazingly useful esxcfg-info utility. This utility can be used to extract statistics and configuration data for the network devices, hardware and storage that are attached to a server. To view the network configuration, you can invoke esxcfg-info with the “-n” option:
$ esxcfg-info -n |more
+NetworkInfoImpl :
==+Network Entities:

To view the hardware present in a server, esxcfg-info can be invoked with the “-w” option:
$ esxcfg-info -w |more
+HardwareInfoImpl :
|----BIOS UUID...................................................0x66 0x9d 0x71 0xf4 0xaa 0x38 0x11 0xd9 0xae 0x6c 0x0 0x30

And for all of the storage folks out there, esxcfg-info provides the “-s” option to print the storage configuration:
$ esxcfg-info -s |more
+StorageInfoImpl :
==+DiagnosticPartition :
==+DiskLunPartition :
|----Name.....................................................vmhba0:0:0:7

There are some other useful options, but I will let folks investigate those when they play around with this super useful utility.
