wait for connection from ds485p before database migration
I did basic testing. Would be nice to get testing in real situation.
I did see weird situation when ds485p refused to connect to migration vdsm service. I explicitly did see this message in ds485p logs:
vdSM collection: RESTRICTED (by flag)But the flag -r was not passed. It even survived several kills of ds485p. The problem disappeared after I started PC built ds485p and restarted ds485p service on dss11-1g. This is mystery for me, but I cannot reproduce any more ...
