Preparing Your Host System
Before starting the upgrade process you will need to prepare your system. This includes
performing a complete system backup and shutting down the system.
2.2.1 Backup the System
As a precaution before starting this procedure you should backup the entire system,
especially data stored on the RAID Array.
2.2.2 Shut Down the System
Unmount from the host system any units that are accessed through the RAID Array 410
that is about to be upgraded. Follow the proper procedures to shutdown the host system.
2.3
Making a Serial Connection with the RAID Controller
You must make a serial connection to the RAID controller to access the Command Line
Interpreter (CLI). The CLI is the user interface built into the RAID controller. It provides
a series of commands for you to create a configuration for the subsystem through the
controller’s software.
See the CLI Reference Manual for detailed descriptions of all CLI commands.
You can make a serial connection to the RAID controller from a maintenance terminal.
2.3.1 Connecting the Cable
To connect a maintenance terminal to a RAID controller follow these steps:
1. Locate the connecting cable that came with the RAID subsystem. It has an RJ12
connector (similar to standard telephone plug) on one end and a 9-pin serial
connector on the other end.
2. Plug the serial connector into the 9-pin serial port/com port 1 of the maintenance
terminal. If a 9-pin serial port is not available, use the 9-pin to 25-pin adapter
(P/N: 12-45238-01) supplied with your StorageWorks RAID Array 410 Subsystem.
3. Plug the RJ12 connector from the maintenance terminal into the maintenance port on
the RAID Array 410 controller (see Figure 2–1).
4. Note which serial port you use; you will need that information if using a
communications program.
