Il Veritas Volume Manager (VxVM) e' un diffuso e flessibile sistema per la gestione dello storage. L'elenco dei comandi e delle funzionalita' e' molto ampio... Nel documento Volume Manager su Unix sono riportati i concetti e le funzionalita' principali. Questo documento invece riporta l'elenco e le opzioni dei principali comandi.

L'elenco dei principali comandi e':
