RAID Array 410 to 450 Upgrade
3–20
EK–SM410–UP. A01
4. Connect a maintenance terminal to the maintenance port of the new controller.
5. Insert the Version 5.0 program card(s) into the new controller(s). The program card
eject button extends when the card is fully inserted.
6. Snap the ESD shield into place over the program card.
7. Power ON the RAID subsystem.
8. If the controller initializes correctly, its green reset LED begins to flash once per
second. If an error occurs during initialization, the OCP displays a code. If necessary,
refer to Chapter 1, Troubleshooting in the Servicing your StorageWorks Subsystem,
HSZ50 Array Controller, HSOF Version 5.0 to analyze the code.
3.8
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 or
a PC.
3.9
Restoring RAID Subsystem Configuration
3.9.1 Setting Target IDs for the Controller
Set the SCSI IDs to be used for your storagesets to the IDs that were recorded in Section
3.4 under “SHOW THIS CONTROLLER.” In this example, SCSI IDs 0, 1, 2, and 3 are
used. Enter the command:
HSZ> set this_controller id=(0,1,2,3)
The CLI will indicate that a restart of the controller is necessary for the change to take
effect. Enter the command:
HSZ> restart this_controller
Set the controller’s operating mode:
HSZ> set this_controller host_function=B
For dual-redundant configurations enter:
HSZ> set failover copy=this_controller
When the CLI finishes initializing, set the preferred IDs. For example, if the preferred
IDs for this controller are 0 and 1, enter the command:
HSZ> set this_controller preferred_id=(0,1)
