Online Addition and Replacement—HP-UX 11i v1
Only
Online Addition and Replacement (OLAR) allows PCI I/O cards,
adapters or controllers to be replaced or added to HP 9000 systems,
without the need for completely shutting down and rebooting the system,
or adversely affecting other system components. This feature is only
available on HP 9000 systems that are designed to support OLAR. The
system hardware uses the per-slot power control combined with OS
support to enable this feature.
NOTE OLAR is supported only on TCP/UDP/IP over HF2 adapters.
Not all add-in cards have this capability, but over time many cards will
be gaining this capability.
The HyperFabric Release Notes contains information about which
HP 9000 systems and HyperFabric adapters OLAR is supported for.
IMPORTANT At this time, Superdome systems are not intended for access by users.
HP recommends that these systems only be opened by a qualified HP
engineer. Failure to observe this requirement can invalidate any support
agreement or warranty to which the owner might otherwise be entitled.
There are two methods to add or replace OLAR-compatible cards:
• Using the SAM utility.
• Issuing command-line commands, through rad, that refer to the
HyperFabric OLAR script (/usr/sbin/olard.d/clicd).
HP recommends that SAM be used for OLAR procedures, instead of the
rad command. This is primarily because SAM prevents the user from
doing things that might have adverse effects. This is not true when the
rad command is used.
For detailed information about using either of these two procedures, see
