Online Addition and Replacement of Networking and
Mass Storage Cards
Online Addition and Replacement (OLAR) is a new HP-UX software feature that allows
for adding and replacing PCI I/O cards (adapters) while a system is running, eliminating
the need to reboot.
This feature enhances overall high-availability 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 MC/ServiceGuard
1
, system availability is significantly improved.
Systems Administration Manager (SAM) provides the system administration interface
for OLAR.
