These data sets contain SMP/E global system information. For the sake of organization, and ease of backup and recovery, it is a good idea to keep them together on a volume shared by all systems that use SMP/E in your complex. If you maintain multiple global zones for subsystems or vendors, the global zone described here should contain ZONEINDEX references to all other zones. This will assist you in cross-zone conditional requisite checking without requiring any changes to your installation's maintenance procedures.
