What command produces this output on AIX?

Depending on your storage backend (IBM/NetApp/EMC), there may be some vendor provided tools that will produce similar output. – matt caffeine Mar 7 '12 at 19:21

The command is:

pcmpath query essmap

No AIX knowledge here, I've just googled the header of that command, like so

It's actually not pcmpath query, it's datapath query, because vpaths are delivered by SDD (datapath), if it was hdisks it would be sddpcm (which is pcmpath). – EightBitTony May 9 '12 at 9:46

It's datapath query essmap. The vpaths are the give-away. Original SDD (used via the datapath command) created vpaths, while the newer and better supported SDDPCM (used via the pcmpath command) uses hdisks only.
