Re: [dm-devel] [multipath] SCSI device capacity mess

I'm not surprised.  We all know how common it is to call a logical unit 
(LU) a LUN, and I've also seen the made-up "LUN ID" (and of course the 
truly ridiculous "LUN number," loved by all those people who key their PIN 
number into the ATM machine).

>And if we are nitpicking, it's EVPD. ;-)

Oh, we're definitely nitpicking, but EVPD is the abbreviation for the 
"Enable Vital Product Data" bit in an Inquiry CDB that tells the target 
you're asking for the Vital Product Data (VPD).  At least that's how the 
SCSI standard uses it.  Maybe EMC has its own terminology here too.
