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 VSP E990 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.
