The SuperPAV mainframe system function provides compatibility with the IBM® SuperPAV host software.
The IBM® HyperPAV function enables you to map alias devices to base devices only within the same CU. If you want to map alias devices in a different CU, you must enable the SuperPAV mainframe system function on the storage system. When the SuperPAV mainframe system function is enabled, you can map an entire collection of alias devices to a single base device that is in a different CU. For details about IBM® SuperPAV and related host commands, see the IBM® documentation.
If the storage system restarts with volatilization (Forced outage with volatile DKC and media chassis, PS-OFF to volatile PS-ON, or Offline microcode replacement), the SuperPAV mainframe system function is reset to the default setting of disabled. If this function was enabled before the volatilization, you must re-enable it after the volatilization.
