Looking at the site stats in Google Analytics, I came across what I had figured for a real oddball search: “vmkpcidivy”, turns out that this is a depreciated command, a left over from an earlier version of the Matrix.
[root@esx root]# vmkpcidivy
vmkpcidivy is deprecated, it is only provided for compatibility with vmkpcidivy -q vmhba_devs
[root@esx root]# vmkpcidivy -q vmhba_devs
To whomever searched that, there it is.
