Operating System Support For Hot-Plug Pci-X Operations - HP Integrity rx4640 Service Manual

equivalent capability card. The existing driver for the old card must be compatible with the
new card.
CAUTION:
(replaced) must be exactly the same as the removed card. This is also known as like-for-like
replacement.
NOTE:
do a combination of an OL-D operation followed by an OL-A operation. This is the equivalent
of an OL-R operation.
• Online Deletion (OL-D)
You can remove an existing PCI-X expansion card. This operation is different from OL-R
because there are no restrictions placed on the type of replacement card that you can use.
In this operation, the drivers are also completely removed from the slot.
NOTE:
• PCI-X Slot Locate (Locate)
To easily locate the PCI-X slot where you want 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 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 deletes the device object, after the card's
successful removal from the slot. You do not have to reinstall 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.
A special OL-R requirement for HP-UX 11i v2 is that the card to be inserted
Windows Server 2003 Enterprise Edition does not support OL-R. Instead, you can
HP-UX 11i v2 does not support OL-D. It does support OL-R.
