Viewing the active or passive path role for a controller
To view the active or passive path role for a controller, complete the following steps.
1.
Select Start a service tool on the Use System Service Tools (SST) menu.
2. Select Hardware service manager on the Start a Service Tool menu.
3. Select Logical hardware resources (buses, IOPs, controllers) on the Hardware Service Manager menu.
4. Select System bus resources on the Logical Hardware Resources on the System Bus menu.
5. Select the Virtual IOP by typing a 9 (Resources associated with IOP) in front of the desired IBM dual
storage IOA.
6.
Press F11 (function key) until Path Role is shown.

To avoid problems during installation, follow the steps exactly as written.
Attention: Disk Arrays can be created either before or after the Dual Storage IOA configuration is set
up.
Each controller requires a supported release of IBM i and verify other possible code pre-requistes. Refer
to the Feature Pre-requisite web site.
Attention: Ensure the adapters are updated with the latest adapter microcode PTF’s as part of the initial
installation.
