I need the step-by-step guide to adding the additional servers. > To get a second server going it needs to be added to the "servers" file on the SCM and you need to create a VSG entry for it by itsel in the VSGDB (volume storage group db). Then you can also create a VSG entry of the form E000010? server1 server2 and use that to make a replicated volume. Then, provided updateclnt etc are running on all hosts, it should start and you should be able to get a replicated volume. The creavol_rep script goes by all the server hosts involved and asks them to create a replica. They then send databases back and these are incorporated into a new master database for volumes at the scm. The scm then propagates this to all servers using updatesrv. I hope this explains things a bit. You cannot extend the volume storage group after the volume is created (maybe in a future release). The manual has a lot of detail but it is not terribly well organised. I'd love for a volunteer to make the instructions clearer - the src rpm (with sgml text and formatting instructions is on the WWW). - Peter - > -- > Med venlig hilsen / Best Regards > Peter Bangs Vej 26, 2000 Frederiksberg, Denmark > Tlf.
