Use the SYBASE_MAX_MULTIPATHS environment variable to override the number of paths iterated when PowerPath is enabled.
On the AIX platform, the method used for fencing EMC PowerPath devices is that the path of each device is fenced separately, which can result in performance issues during startup.
To increase startup performance when PowerPath is enabled, set the SYBASE_MAX_MULTIPATHS environment variable to 1, which will cause Adaptive Server to fence each device only once and allow PowerPath to broadcast the fencing operation to all of the paths.
