I believe auto-failover is a configurable option with GCO, unless something has changed recently (I didn't go look at the docs). The default is operator confirmation before fail-over, but I have agreed to configured GCO for auto-failover before if a split-brain did not present any significant risk to the customer (eg the customer said it was OK and their preference, and after inquiring into the facts of the situation, I agreed with their conclusions).

GCO = Operator confirmed failover. So in GCO, an operator makes a choice to startup on old data or wait on original primary. This is not possible inside a single cluster. And for bunker, this is a GCO config as well [Sent from my Nokia E62 handheld via goodlink] -----Original Message----- From: Pavel A Tsvetkov [mailto:[EMAIL PROTECTED] Sent: Wednesday, March 14, 2007 02:09 AM Pacific Standard Time To: Jim Senicka; Veritas-ha@mailman.eng.auburn.edu Subject: Re: Re: [Veritas-ha] Veritas Volume Replicator in Replicated DataCluster question Hello Jim! Thank you for the answer. But if I have a choice for replication mode in global cluster it can be useful to have the same thing in RDC. Let it be not up-to-date data on the Secondary , but it is still consistent. :) So the application can be started. And we should take the bunker into consideration! The bunker uses synchronous connection with Primary SRL, so the asynchronous Secondary site can have up-to-date data from the bunker. So if we use bunker and the bunker agent it is quite possible to take RDC in asynchronous mode. With best regards, Pavel >>We do not support an automatic failover to out of date secondary. So RDC is sync only. If you need async, you need to not treat the the >replication like a shared disk, and instead treat it like replication.
