[MGM] Disallow prepare with empty pargs.opts when mTapeEnabled = true
Disallows sending xrdfs prepare
with no options when sending the request to a CTA instance (mTapeEnabled = true
).
Previously prepare
had the same behaviour as prepare -s
in the MGM, but without the -s
flag, the XRoot framework does not pass back the request ID to the client.
prepare
without -s
has a different interpretation on non-tape backends and this behaviour is unaffected.
