Online Addition and Replacement of Networking and
Mass Storage Cards
Online Addition and Replacement is an HP-UX feature that enables addition or
replacement of PCI I/O cards (adapters) while a system is running, eliminating the need
to reboot.
This feature enhances overall high-availability because 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 Serviceguard
1
, system availability is significantly
improved.
Systems Administration Manager (SAM) provides the system administration interface
for OLAR.
