Online Addition/Replacement (OLAR) of PCI Cards
OLAR Overview and Concepts
Chapter 680
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-port card, suspending or deleting
drivers for the target card slot also suspends individual drivers for
the multiple hardware paths on that card.
During a card replacement operation, 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.
