Installing Original Controller
1. If installing option kit DS-HSZ22-AA, add the second SIMM to the
original controller. If installing option kit DS-HSZ22-AB, replace the
existing SIMM with the two remaining SIMMs supplied with the kit.
(see “Install Two SIMMs Into Second Controller” for instructions).
2. Install the second controller into the pedestal (or controller shelf) and
power up the system. The system is now in the dual-redundant operating
mode.
3. Locate the second serial cable that came in the second controller kit.
Connect this cable to the second controller serial port on the RA3000
and to COM 2 port and restart SWCC in serial mode. You now have two
serial connections.
4. To check that the controller pair is in redundant mode, click the
Controller icon. Properties for both controllers will be visible.
Firmware revision of both controllers must be identical. If either
controller is shown in gray, refer to the Getting Started RAID Array
3000 Installation Guide for your host system for more detailed
instructions.
Configuring a Dual Controller Installation
for a Single Serial Port
This section describes how to configure your RA3000 storage system for dual
controller operation when only one serial port is available on the host. If
required, refer to the Getting Started RAID Array 3000 Installation Guide for
your host system for SWCC installation instructions. The information in this
section is divided as follows:
■ Configuring the RA3000 storage system for dual-controller operation
■ Connecting to your dual controller storage system using a serial
connection
■ Verifying the controller operating parameters
