Verifying the level of prerequisite software
Before you can install GPFS, verify that your system has the correct software levels installed.
If your system does not have the prerequisite AIX® level, refer to the appropriate installation manual before proceeding with your GPFS installation. See the IBM Storage Scale FAQ in IBM® Documentation for the latest software levels.
To verify the software version, run the command:
WCOLL=/tmp/gpfs.allnodes dsh "oslevel"
The system displays the current AIX level.
