We have Sybase ASE 12.5 Database server running on a HP-UX B.11.11 U 9000/800 with
SAN (SYMMETRIX 8830) using rawpartitions. We are in the middle of moving the SAN to a new Disk Array DMX8.

Our SAs have brought up the option of using File Systems instead of raw partitions. I would like
to see if any of you have  anyexperiences in moving from raw to file systems. We do have asynch io enabled with raw partitions now. In the past versions, i experienced performance
problems using file systems and I was not able to bring up the devices using asynch io.

Does Sybase has any recommendations (URLs) on this? Are there any issues taking this path of filesystems?
