1.1.3 Precautions
In general, you should follow routine ESD protection procedures when handling
controller modules and cache modules and when working around the cabinet and shelf
that houses the modules.
Follow these guidelines to further minimize ESD problems:
•
Use ESD wrist straps, antistatic bags, and grounded ESD mats when handling
controllers and cache modules.
•
Obtain and wear an ESD wrist strap on your wrist. Make sure the strap fits snugly.
•
Attach the lead on the ESD strap to a convenient cabinet grounding point.
•
After removing a module from the shelf, place the module into an approved antistatic
bag or onto a grounded antistatic mat.
•
Remain grounded while installing a replacement module.
CAUTION
Follow program card guidelines or damage to the
program card and controller software can result.
1.2
Preparing Your Host System
Before starting the upgrade process you will need to prepare your system. This includes
performing a complete system backup, recording the volume group configurations, and
shutting down the system.
1.2.1 Backup Data Files
As a precaution before starting this procedure you should backup the entire system,
especially data stored on the RAID Array.
1.2.2 Shut Down the Host 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.
1.3
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.
