Nope, savevg is a link to mksysb, at least is on later versions of
AIX. Issue "ls -l $(whence savevg)" to see if it is the case on 4.1.4

Yes, use a different backup tool. savevg backs up ALL files in the
specified volume group except those specified in /etc/exclude.<volume
group>

The -p option is only valid in 4.2 or later versions of AIX

Experiment and see what works best with your tape drive.

Yes, it's unsupported, in fact, the last version of AIX (4.3.3) goes
out of support shortly. But apart from that, no.
