The vmphyinv utility has the following features:
Can be run from any master server, media server, or SAN media server.
Can be used with bar coded tape libraries because it verifies the contents of the media.
Supports the remote administration. You do not need to run vmphyinv from the host to which the drives are attached.
Tries to use multiple drives in a robot even if the drives are attached to different hosts.
Can be used to inventory a single media in a standalone drive. Use the -u option or the -n option to specify the drive; the drive must contain media and it must be ready.
