Online Addition/Replacement (OL*) of PCI Cards
OL* Overview and Concepts
Chapter 6 71
OL* Overview and Concepts
OL* stands for Online Addition and Replacement. This term refers to the
ability of a PCI I/O card to be replaced (removed and/or added) to an
HP-UX computer system designed to support this feature without the
need for completely shutting down and re-booting the system or
adversely affecting other system components. The system hardware uses
the per-slot power control combined with operating system support to
enable this feature.
Not all add-in cards have this capability, but over time many cards will
add this capability.
IMPORTANT Certain “Classes” of hardware are not intended for access by users. At
this time, this includes SuperDome systems. HP recommends that these
systems only be opened by qualified HP Engineers. Failure to observe
this requirement can validate any support agreement or warranty to
which the owner might otherwise be entitled.
Important Terms and Concepts
For SNAplus2, the addition or replacement of an OL*-compatible card
should be done using the pdweb utility. This utility is available either
from the command line interface or from within SMH. For information
on the utility see pdweb (1M).
For detailed information about the use of this procedure, you should refer
