Managing PCI Cards with OLAR
PCI Card OLAR Overview and Concepts
IMPORTANT In many cases, other interface cards and slots within the system are
dependent upon the target card. For example:
• If the target card is a multiple-function card (MFC), suspending
drivers for the target card slot also suspends individual drivers for
the multiple hardware paths on that card. If the target card has
multiple ports, then all individual ports will be suspended and then
resumed when the card is replaced.
• In currently shipped systems, a power domain consists of a single
card slot, however future systems may provide multi-card power
domains. In this case, if the target card slot is in a multi-card power
domain and you temporarily stop power to the target card slot, you
will also stop power to any other card slots (affected card slots) in that
same power domain.
During a card replacement, SAM performs a Critical Resource Analysis,
which checks all ports on the target card for critical resources that would
be temporarily unavailable while the card is shut down.
Planning and Preparation
For the most part SAM prevents you from performing OLAR procedures
that would adversely affect other areas of the server. This section
provides you with important information that can help minimize errors
or problems when performing OLAR procedures.
target card / target card slot The interface card which will be
added or replaced using OLAR, and
the card slot it resides in.
affected card / affected card slot Interface cards and the card slots they
reside in which are in the same power
domain as the target slot. Currently
multi-slot power domains are not
implemented.
