We don't even pay extra to have them come with external labels on them,
let alone internal labels!  Also, I'm lucky that it's dedicated to AIX
for ADSM and I'm the only one exercising it right now so I don't have to
worry about conflicts unless I forget and do something in ADSM.

I had a feeling it might be doing this intentionally.

Thanks for the info.
