HYPERPAV

Use the HYPERPAV statement to indicate whether HyperPAV mode is to be used and, if so, whether in BASEONLY mode or XPAV mode. The absence of this keyword in the parmlib member will cause no change to the system. For the initial IPL, the absence of the HYPERPAV keyword causes the system to IPL in HYPERPAV=NO mode.

HYPERPAV=NO|BASEONLY|YES|XPAV

Specifies whether HyperPAV mode is to be used.

NO

Specifies that HyperPAV mode is not to be used.

BASEONLY

Specifies that I/O is to be run only on non-PAV-alias devices in HyperPAV mode.

YES

Specifies that HyperPAV mode is to be used.

XPAV

Specifies that HyperPAV mode is to be used, and wherever possible, allow aliases to be used for peer control units in the defining alias management group (AMG). This HyperPAV mode is also known as SuperPAV mode.

Control units on a storage controller with the exact same paths, in order, and those that share the alias management group number, as defined by the storage controller, are eligible to share alias devices when the system is operating in SuperPAV mode.

Default: NO
