Maintenance and Service Guide

Shutting down the subsystem

Use the following steps to shut down a subsystem:

1. Connect a PC or terminal to the maintenance port of one of the subsystem

array controllers.

2. From a host console, stop all host activity to the array controllers and

dismount the logical units in the subsystem.

3. If you are using a Windows NT or Windows 2000 platform, shut down

the server.

4. Shut down the array controllers:

■ In single-controller configurations, shut down “this controller”

with the following command:

SHUTDOWN THIS_CONTROLLER

■ In dual-redundant controller configurations, shut down the “other

controller” first, then shut down “this controller” with the

following commands:

SHUTDOWN OTHER_CONTROLLER

SHUTDOWN THIS_CONTROLLER

Note: After the array controllers shut down, the Reset buttons and the first three LEDs

on the OCP turn on (see Figure 38). This process takes several minutes, depending on

the amount of data that needs to be flushed from the cache modules.

5. Proceed only after the Reset buttons and the first three LEDs stop flashing

and remain solid.
