High-level MES upgrade steps
1. Stop all I/O to one or more file systems that are mounted on the MES target ESS 3000 system.
2. Unmount one or more file systems and prepare GPFS to stay in the offline mode.
3. Shut down GPFS.
4. Power off ESS 3000.
5. Install the memory.
6. Power on ESS 3000 and do basic checks.
7. Configure GPFS page pool size to the 60% target.
