Online Installation of the RAID160 SA Controller
If your system has one or more slots that support OLAR—and you want to use OLAR to install the controller
in one of those slots—follow these steps:
Step 1. Be sure version B.11.31.01 or later of the ciss driver (RAID160 SA software) is installed on your
system. See “Locating Software for the RAID160 SA Controller” on page 34.
Step 2. Install the RAID160 SA controller in your HP-UX system according to the procedure described in
the Interface Card OL* Support Guide. This document can be viewed or downloaded at
http://www.docs.hp.com, or a hard copy can be ordered from HP.
TIP To improve performance, install the RAID160 SA controller in a non-shared PCI slot
running at PCI 2X speed or greater. To identify the highest-performance slots, see
the documentation for your server.
IMPORTANT When using OL* to add or replace a RAID160 SA controller, it is important to pay attention to
the warning messages that will be displayed.
It is necessary to remove the SCSI cables from a RAID160 SA controller that is about to be
online replaced, before the PCI slot is powered off.
It is necessary to wait until power has been restored to the PCI slot, before the SCSI cables are
connected to an add-in or replacement RAID160 SA controller.
If the SCSI cables are removed, or connected, to the RAID160 SA controller while the PCI slot
is powered off, the OLAR procedure will have to be repeated. See “RAID160 SA Controller OL*
Error Recovery” on page 41.
