Replacing a Smart Array P800 Controller Online

You can use Online Addition, Replacement, and Deletion (OL*) to replace the Smart Array Controller online in 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 Smart Array Controller without adversely affecting other system components. Table 1-2 shows OL* feature support for Smart Array P800 controllers:

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”.




	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 P800 controller online, follow these steps:

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://docs.hp.com/en/netcom.html
Confirm that the controller is in a slot that supports OL*.
To determine the capabilities of the slots on your system, see one of the following documents:
- I/O Slot Matrix - Entry Class Integrity Servers, at:
  http://docs.hp.com/en/hw.html
- The documentation for your server, at:
  http://docs.hp.com/en/hw.html
To replace the controller, follow the procedures in the latest edition of the Interface Card OL* Support Guide for your HP-UX version.
- For instructions on using OL* on HP-UX 11i v2, see the Interface Card OL* Support Guide at:
  http://docs.hp.com/en/oshpux11iv2.html
- For instructions on using OL* on HP-UX 11i v3, see the Interface Card OL* Support Guide at:
  http://docs.hp.com/en/oshpux11iv3.html
For instructions on opening the system enclosure and working with PCIe cards, see the server documentation at:
http://docs.hp.com/en/hw.html
CAUTION: Electronic components can easily be damaged by small amounts of static electricity. To avoid damage, follow the guidelines in Appendix A.

When the operation is complete, confirm that the access panel or cover is correctly installed and secured.




	CAUTION: Do not operate the server with the access panel removed for extended periods of time. The access panel protects thermally sensitive components by ensuring the proper airflow through the server and minimizes personal contact with hazardous energy levels.
