HP P4000 HP Smart Array SAS controllers for Integrity servers support guide - Page 29

Installing the controller offline To install a Smart Array controller on a server running HP-UX, follow the procedures in the HP-UX chapter of the installation guide for your controller. Installation guides are available on the HP website at http://www.hp.com/go/hpux-iocards-docs. Click the link for your HP-UX version. Installation guides are listed alphabetically in the "Setup and install - general" section. NOTE: If you purchased the Smart Array P400 Controller as an option kit upgrade, follow the installation instructions in the server-specific installation guide provided in the upgrade package. Adding or replacing a Smart Array controller online You can use Online Addition, Replacement, and Deletion (OL*) to replace some Smart Array controllers online in HP-UX systems that support OL*, without powering off and rebooting the system. (Some Smart Array controllers do not support this feature.) The server hardware uses per-slot power control and HP-UX OL* utilities to enable online addition or replacement of Smart Array Controller without adversely affecting other system components.

During a Smart Array Controller online 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, you can replace the controller when the system is offline. See "Installing the controller offline" (page 29). IMPORTANT: Other controllers (host bus adapters) and slots in the system can be dependent on the controller that is targeted for replacement. For example, if the target controller has multiple channels, suspending or deleting drivers for the target PCIe slot also suspends individual drivers for the multiple hardware paths on the controller installed in that PCI slot. To replace a Smart Array controller online: 1. Confirm that you have the minimum ciss driver version to support OL* on your system. See the HP Smart Array Controller Support Matrix at http://www.hp.com/go/hpux-iocards-docs. Click the link for your HP-UX version. Support Matrix documents are listed alphabetically in the "General reference" section. 2. Confirm that the controller is in a slot that supports OL*. To determine the capabilities of the slots on your system, see the documentation for your server at http://www.hp.com/go/Integrity_Servers-docs. Installing the controller offline 29
