Scripts in the directory
/usr/sbin/olrad.d/
Each OLAR-capable card’s driver(s) may have associated
scripts in the /usr/sbin/olrad.d/ directory. Each driver’s
script accepts the following command-line arguments: the
action to perform and path for the slot for which the action is
performed.
The SAM and Partition Manager utilities automatically run
these scripts, as needed, when performing PCI card online
addition or replacement tasks.
Normally, the driver OLAR scripts are not invoked manually by
administrators.
These scripts’ actions include various preface–, prepare–, and
post-replace tasks and post-add tasks.
I/O Chassis Hardware Hardware in each I/O chassis includes PCI card slots, card slot
dividers, and power and attention indicators (LEDs) for each
slot.
HP rp7410 and rp8400 servers also have PCI card slot latches.
Note that the I/O chassis locations and other features of I/O
chassis hardware differ in the various HP nPartition server
models.
Refer to the chapter nPartition System Overviews on page 31
and the section PCI Card Slot Latches and Doorbells on
page 378 for nPartition I/O hardware details.
/usr/lib/libolrad.1 The libolrad library is used by the rad command and other
utilities such as SAM and Partition Manager to support PCI
card slot inquiry and online addition and replacement tasks.
