Use the default PowerPath multipath settings.
First, run the SCSI device rescan (rescan_scsi_bus.sh).
To detect, rescan, and configure new paths use the powermt config command.
Use PowerPath commands/scripts to scan and remove stale paths (powermt check).
The powermt restore command can be used to detect path changes faster than PowerPath will discover them on its own.
Note: See Appendix B: AIX, GPFS, and PowerPath with NDM for important information regarding PowerPath and AIX 6.x with GPFS.
