Save -M is not supported, if save set is spanned on several volumes you cannot

What? Version 7.1.x of Unix or Windows . By undocumented (never heard
of it) do you mean unproven/experimental? Are you using it in production
with anything?

Are you saving this splits a savestream into 4 sessions as seen in the
nwadmin? ie..the sessions could go to seperate tapes (as the user here
wants)?

It seems odd that this feature is not documented/advertised.. anyone using
