Online Addition/Replacement (OLAR) of PCI Cards
OLAR Overview and Concepts
Chapter 6 79
OLAR Overview and Concepts
The letters O, L, A and R stand 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 V-Class and 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 waranty to which the owner might otherwise be entitled.
Important Terms and Concepts
For SNAplus2, the addition or replacement of an OLAR-compatible card
should be done using the SAM utility.
