Online Addition and Replacement—HP-UX 11i Only
Online Addition and Replacement (OLAR) allows PCI I/O cards, adapters or
controllers to be replaced or added to HP 9000 systems, without the need for completely
shutting down and rebooting the system, or adversely affecting other system
components. This feature is only available on HP 9000 systems that are designed to
support OLAR. The system hardware uses the per-slot power control combined with OS
support to enable this feature.
Not all add-in cards have this capability, but over time many cards will be gaining this
capability.
The latest HyperFabric Release Notes contains information about which HP 9000
systems and HyperFabric adapters OLAR is supported for.
IMPORTANT At this time V-Class and Superdome systems are not intended for access by users. HP
recommends that these systems only be opened by a qualified HP engineer. Failure to
observe this requirement can invalidate any support agreement or warranty to which
the owner might otherwise be entitled.
