Chapter 6: Maintaining the storage system
Ongoing proper maintenance of the storage system maintains the reliability of the storage
system and its constant availability to all hosts connected to it.
For more complex maintenance activities, contact customer support.
Storing the storage system
If the storage system does not receive power for more than six months, the battery can
become discharged and possibly damaged. To avoid this situation, charge the battery for
more than three hours at least once every six months.
Note: Do not store the equipment in an environment with temperatures of 104ºF
(40ºC) or higher because battery life will be shortened.
Powering off the storage system
Use the following procedure to power off the storage system. The main switch on the
controller chassis is used to power off the storage system.
Before you begin
Ensure that all software-specific shutdown procedures have been completed. Refer to the
■
applicable user manuals for details.
Ensure that all I/O activity to the storage system has stopped. You can vary paths offline
■
and shut down the attached hosts.
Procedure
1. Press the main switch on the controller chassis for approximately three seconds until the
POWER LED on the front of the chassis changes from solid green to a blinking status.
2. Release the main switch and the POWER LED returns to solid green after blinking for
approximately three seconds.
The power-off process begins. The process takes approximately 18 minutes or longer
depending on the amount of data that needs to be written. The POWER LED is solid
green during the powering off process. The POWER LED changes from green to amber
when the process is completed.
3. Verify the POWER LED on the front of the storage system changes from green to amber.
4. To stop the power supply, remove the power cables from the power supply units on the
controller chassis and drive box.
