Power On Procedures; Power Off Procedures - Hitachi G1500 Hardware Manual

Power on procedures

Before you begin
Confirm the storage system is in idle mode. See
■
Note: The control panel includes a safety feature to prevent the storage
system power from being turned on or off accidentally. The PS ON/OFF switch
does not work unless the ENABLE switch is moved to and held in ENABLE
while the power switch is moved to ON or OFF.
Perform the procedure to turn on the storage system. If applicable, see
panel (on page 119)
Procedure
1. On the control panel, check the amber BS LED and make sure it is lit. It indicates
that the storage system is in idle mode.
2. In the PS area on the control panel, move the ENABLE switch to the ENABLE position
and hold it there. While holding the switch in the ENABLE position, move the PS
ON/OFF switch to ON. Then release both switches.
3. Wait for the storage system to complete its power-on self-test and start processes.
Depending on the storage system configuration, this can take several minutes.
The storage system does not go to the READY state until the cache backup batteries
are charged to at least 50%. The process can take 90 minutes if the batteries are
completely discharged. The storage system generates a SIM that provides the status
of the battery charge. See
about the batteries.
4. When the system self-test is complete and all components are operating normally,
the green READY LED turns ON and the storage system is ready for use.
If the ALARM LED is also ON, or if the READY LED is not ON after 20 minutes, contact
customer support for assistance.

Power off procedures

Before you begin
Confirm all maintenance and software-specific shutdown procedures have been
■
completed.
Verify all I/O activity to the storage system has stopped. You can vary paths offline
■
and shut down the attached hosts.
Follow this procedure exactly when powering off the storage system.
