We are running ORACLE RAC + ASM on RHEL.
we are using VXDMP for RAW disk.
we have an issue with ASM disk access for Oracle RAC. On startup, ASM auto-discovers its disks. Due to the way multipathing is setup on these servers (relying on Veritas DMP) it finds the first active device path instead of finding a multipath instance for it.
The problem we are trying to resolve here is that if the in-use path goes down (such as from a SAN online maintenance) then oracle panics and crashes due to the loss of disk access with ASM.
can you guys suggest me the solution to this?
