On Line Addition and/or Replacement (OLAR)
NOTE
The HP Praesidium SpeedCard, version A5486A, can only take
advantage of OLAR features if your system is running the HP-UX 11i
operating system and has a PCI bus.
OLAR Concepts for PCI Cards
Introduction
The letters O, L, A and R stand for On Line Addition [and] Replacement.
This, of course, refers to the ability of a PCI I/O card to be replaced on an
HP-UX computer system designed to support this feature without the
need for completely shutting down, then 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.
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 a qualified HP Engineer. Failure to
observe this requirement can validate any support agreement or
warranty to which the owner might otherwise be entitled.
Important Terms and Concepts
The addition or replacement of an OLAR-compatible card may be done in
either one of two ways:
1. Using the SAM utility.
2. Issuing command-line commands using rad.
If detailed information about the use of either of these two procedures is
required, you should refer to the following document:
