Hi, Not long ago, we bought a product that uses Sybase IQ as it's backend database.
The company from which we bought it claims it cannot put it's raw devices under Veritas control (/dev/vx/rdsk/dg/vol), because it is not supported. As a reference, they sent a 5 years old document, titled "SYBASE IQ USING EMC CLARiiON STORAGE". In this document, there one paragraph that says: 5. Create one single LUN on each RAID group, as close to 2TB as possible and present it to host(s) . Use of Volume Manager is not recommended with Sybase IQ as it complicates the environment, consumes CPU resources on host(s), introduces product dependencies and lowers the performance. This sounds very general to me, and without any specific technical reason. Can anyone on this list shed some light on this issue (best practices, own experience, official documents etc.) regarding this issue? _______________________________________________ Veritas-ha maillist - Veritas-ha@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-ha
