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.
