Activating the zHPF program product
The zHPF PP license is required to activate zHPF on the storage system. Launch the Remote Web
Console and use the following information to activate the zHPF PP license:
• Product name: P9000 for Compatible High Performance FICON Connectivity
Enabling the zHPF function
After the zHPF PP license is activated, the zHPF function is not enabled automatically. You need
to enable zHPF manually by performing either Option (1) or Option (2):
• Option (1): From one device under online CU, issue the DS QD,Device number,VALIDATE
command. Repeat this operation in all online CUs.
OR
• Option (2): From one online channel path, issue the VARY PATH(Device number, Channel
path ID),ONLINE command. Repeat this operation in all online CUs and device numbers.
To check the zHPF status, issue the D M=DEV(device number) command. The status
“FUNCTIONS ENABLED=ZHPF” indicates that the zHPF function has been enabled.
Installing zHPF in a switch cascading configuration
In the storage system, when the zHPF PP is installed, the zHPF feature is enabled per channel path.
For point-to-point (direct) connection and single-switch connection, zHPF is dynamically enabled
per channel path. However, in cascading-switch connections, it is not automatically enabled (if
you perform option (1) or (2) from (page 19) to enable zHPF, zHPF IO would not be issued).
