There are times when a normal, planned shutdown is appropriate.
But as server downtime becomes less desired and accepted, OLA/R
(on-line addition and replace) functionality and DLKMs (dynamically
loadable kernel modules) can help you to avoid shutting down a server
in many cases.
On-line Addition and Replacement of PCI Cards (OLA/R) |
 |
HP-UX's On-line Addition and Replacement of PCI Cards
(OLA/R) features enable you to replace a faulty interface card or
add a new interface card to a running system, without impacting
the system's users.
Refer to Configuring HP-UX for Peripherals for
detailed OLA/R concepts and procedures.
Dynamically Loadable Kernel Modules (DLKM) |
|
The DLKM infrastructure is an HP-UX operating system feature
that enables you to dynamically load “DLKM-enabled” kernel
modules into, or unload them from, the running HP-UX kernel, without
the need to re-link the entire kernel and reboot the system. Although
the base HP-UX Release 11i Version 1.5 is not released with DLKM-enabled kernel
modules, certain optional and add-on HP-UX software is available as
DLKM-enabled modules. Refer to the white paper Managing
and Developing Dynamically Loadable Kernel Modules for
detailed DLKM concepts and procedures.
