Removing and Replacing Hot-Plug PCI-X Cards
The HP Integrity rx4640 server supports PCI-X hot-plug technology and offers six PCI-X, hot-plug capable
slots.
CAUTION
There are restrictions on the number of PCI-X cards that can be installed in the rx4640 server
at any given time, depending on the cards being used.
Maximum quantity for any I/O configuration using 337972-B21, AB287A, or A9890A cards:
•
Three 337972-B21 cards maximum plus three unpopulated slots
•
Two AB287A cards maximum plus four unpopulated slots
•
Three A9890A cards maximum plus three unpopulated slots
Failure to observe this caution will result in server degradation, or server failure.
PCI-X Specifications
PCI-X technology enables the following hot-plug operations. For procedures with step-by-step instructions
describing how to add, replace, delete, and locate PCI-X cards see “Hot-Plug Operation Procedures” on
page 77.
•
Online Addition (OL-A)
You can install new PCI-X expansion cards in previously empty slots without powering down the server.
•
Online Replacement (OL-R)
You can replace a previously occupied slot with a new PCI-X expansion card by suspending the driver.
This operation combines removing an active card and replacing it with an equivalent capability card. The
existing driver for the old card must be compatible with the new card.
CAUTION
A special OL-R requirement for HP-UX 11i v2 is that the card to be inserted (replaced)
must be exactly the same as the removed card. This is also known as like-for-like
replacement.
NOTE
Windows Server 2003 Enterprise Edition does not support OL-R. Instead, you can 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
HP-UX 11i v2 does not support OL-D. It does support OL-R.
