Removing and Replacing Hot-Plug PCI-X Cards

To easily locate the PCI-X slot at which you wish to perform a hot-plug operation, you can command the attention LEDs, on the OLX divider and the I/O baseboard, to blink and act as visual cues to the active slot location. This operation is always initiated through a software or web interface and is optional to the operating system on your HP server.

Operating System Support for Hot-Plug PCI-X Operations

The capability of each operating system to support hot-plug PCI-X operations is different. The following explanation details the capabilities of each operating system.

NOTE Open VMS does not support hot-plug PCI-X operations.

•HP-UX 11i v2

HP-UX 11i v2 supports only OL-A, OL-R, and Locate hot-plug PCI-X operations.

In OL-R, it is a requirement that the card to be inserted (replaced) be exactly the same as the card being removed. During this OL-R operation, HP-UX 11i v2 suspends the device driver and re-enables it upon completion of the OL-R operation.

In HP-UX 11i v2, the Locate function is only available through the command line or web interface.

•Windows Server 2003 Enterprise Edition

Windows Server 2003 Enterprise Edition supports only OL-A and OL-D hot-plug PCI-X operations.

In OL-D, Windows Server 2003 Enterprise Edition will delete the device object, after the card’s successful removal from the slot. You do not have to re-install drivers for the deleted device on subsequent insertions or reboots

To perform a card replacement hot-plug PCI-X operation in Windows Server 2003, you must first perform an OL-D operation followed by an OL-A operation.

•Linux Red Hat Advanced Server 2.1

At this time Linux RHEL4 U3 does not support hot-plug PCI-X technology.

Table 4-6 shows hot-plug operations that are available in HP-UX 11i v2, Windows Server 2003 Enterprise Edition, and Linux Red Hat Advanced Server 2.1 operating systems.
