Online Addition and Replacement of I/O
Adapters (new)
Online Addition and Replacement (or OLAR) of PCI I/O cards (adapters)
is a new HP-UX software feature that allows for adding and replacing
PCI I/O cards while a system is running, eliminating the need to reboot.
This feature enhances an overall high availability solution since the
system can remain active while an I/O adapter is being added or
replaced. When combined with other high availability products, such as
HP MC/ServiceGuard, system availability is significantly improved.
SAM provides the system administration interface for OLAR. The first
release of OLAR in HP-UX 11i provides support for the addition and
replacement of I/O cards on L-Class, N-Class, and Superdome systems.
Many future HP 9000 systems are being designed with this feature as
well.
