5–36 Configuring an HSG80 Array Controller
Shutting Down Your Subsystem
Follow these steps to shut down your StorageWorks subsystem:
1. On the host, dismount the storage units in your subsystem.
2. Connect a maintenance terminal to one of the controllers in your subsystem.
3. Shut down the controllers. If you have dual-redundant controllers, shut down the
“other controller” first, then shut down “this controller.” Use the following
syntax:
SHUTDOWN OTHER_CONTROLLER
SHUTDOWN THIS_CONTROLLER
NOTE: This process can take up to five minutes to complete depending on the
amount of data to be flushed from cache.
4. Turn off the power to the subsystem.
5. Unplug the subsystem’s power cord.
6. Disable the ECB by pressing its shut-off button until its status light stops
blinking—about two seconds.
