As dsh is a standard AIX command (package dsm.dsh) starting a parallel shell on multiple server, using ssh mechanism, dshvio is a shell (but sequential only) that can be used on VIOS as padmin or root.

In the same idea, dcp will copy a file on many server in parallel, while dcpvio will copy in sequential mode for padmin user only
