Online Addition/Replacement (OL*) of PCI Cards
OL* Overview and Concepts
Chapter 672
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, pdweb 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.
