You can look at Lifekeeper by Steeleye.  They have an eval copy you can use
and try out.  This is the setup that compaq is using for linux san clusters
and the docs say it supports transparent failover and the app locks the data
to the current server that is accessing and then releases for the next to
prevent data corruption.  This might be what you are needing and their
requirements are a san, qlogic cards, and intel architecture server with
either redhat 6.x or 7.x and it looks like you have all this covered.  You
can access the info at and is available outside of compaq.

and you work for dell :-/.  i was hearing how dell is a really flat
company - is it now so big you guys in dell don't get told about
leading edge stuff either ?

uhm.  what's the difference in "support" ?  7.0 is a 2.2 kernel.  7.1
is 2.4.  i was told navisphere runs under Linux and has been available for
months on that platform - was i incorrectly informed ?

hmm.  i will keep this in mind.  thanks for the feedback michael.
