Installing the Adapter Hardware Online

Online Addition, Replacement and Deletion (OL*) enables you to add the AH303A Host Bus Adapter online to HP-UX systems that support OL* without powering off and rebooting the system. System hardware uses per-slot power control and HP-UX OL* utilities to enable online addition or replacement of an adapter without adversely affecting other system components.

During an online addition or replacement operation, the system performs a Critical Resource Analysis (CRA), which checks all channels on the target controller for critical resources that become temporarily unavailable when the controller is shut down. If critical resources will be affected by the OL* procedure, replace the controller when the system is offline. See “Installing the Adapter Hardware Offline” (page 13).

To install an AH303A controller online, follow these steps:

1.Install updated operating system drivers and utilities, if needed.

See “Downloading Software” (page 12) and “Installing Software” (page 13).

2.Select the slot to install the controller in.
