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.

POWER
LED on the front of the chassis changes from solid green to a blinking status.
2.
Release the main switch and the
POWER
