Actually, the heartbeat has been the biggest pain in the but of ServiceGuard. Its caused 99.99% of the failures. Granted once it was a failed network card. All in all though, I have been pretty happy with ServiceGuard. And ours is dedicated and protected:-)

Worked well, after our SA rebuilt the servers from ground 0. Adding it on to an existing server is ok, but somewhat unstable. One item to be VERY careful of. The heartbeat cable, in our case a ethernet thin line, needs to be on a dedicated link, preferably a purchased vs. custom made cable, and protected from accidental disconnect. Ours got disconnected by a contractor working in the computer room because "it was in his way". The resulting reboot of the backup server and forcible takeover of the disk farm absolutely destroyed the database. We had more file corruption than I ever could have imagined. Consequently we abandoned ServiceGuard & are going to standby databases instead.

I am looking for inputs from anybody who has experience in both MC/Serviceguard (MC/S) as well as Sun cluster implementation. If a DBA/SA team has lots of experience in implementing MC/Serviceguard clusters on HP and trying to move to SunClusters for HA solution ... a) What are the common things between MC/S and and Sun clusters (ex: about 5 minute fail-over time, fixed IP address, 2 or more nodes in a cluster, disk sharing etc..) b) Any differences between these... What are the things to watch out for (assuming the team already knows in and out of MC/Serviceguard) Thank you in advance...
