Properly configuring multiple paths to the host with AIX 6.x and PowerPath requires additional steps to properly configured SRDF/Metro R2 devices:
The latest emc_pp_configure.sh script may be obtained from the following link:
https://support.emc.com/search/?text=powerpath&facetResource=ST&facetProductId=1726
Note: This script MUST be used in order to properly use an SRDF/Metro R2 device in this environment. Failing to run the script following the configuration of the new native target devices can lead to data unavailability.
After SRDF/Metro enters Active mode for the first time, the SRDF/Metro R2 devices (appearing to the host as additional paths to the source devices) may then be masked by the user and made available to the host. After running cfgmgr to create the host native devices, the emc_pp_configure.sh script below must be run immediately following the completion of the cfgmgr command. The script will configure the new R2 devices into PowerPath by copying the attributes of the PowerPath hdiskpower pseudo devices into the new native devices and reconfigure the native devices.
