Description

Resolution:
Do not use the mincache=direct, mincache=unbuffered, and mincache=dsync mount options for VxFS file system. Those mount options can override the file mode a user space application ( EMS ) opts to use, namely it changes non-synchronous I/O to synchronous I/O resulting $sys.failsafe and $sys.nonfailsafe having the same performance characteristics.
