•
You must have the Storage Administrator (Provisioning) role to perform this task.
To disable Hyper Parallel Access Volumes from z/OS:
1.
Issue the following commands to all base devices in the corresponding CU:
V base_device_number1-base_device_number2,OFFLINE
CF CHP(channel_path1-channel_path2),OFFLINE
2. Issue the following command from the host system console to disable the Hyper Parallel Access
Volumes option on the host computer.

syntax and an example of this command.
Disabling Hyper Parallel Access Volumes from z/OS when multiple storage
systems are used

other storage systems which are accessed from the corresponding host.
To disable Hyper Parallel Access Volumes from the target storage system only:
1.

V base_device_number1-base_device_number2,OFFLINE
CF CHP(channel_path1-channel_path2),OFFLINE
2. Uninstall Hyper Parallel Access Volumes on the Remote Web Console.
3. Issue the following commands to all base devices in the corresponding CU.
CF CHP(channel_path1-channel_path2),ONLINE
V base_device_number1-base_device_number2,ONLINE
