Turning off the storage subsystem
The DS3300 is designed to run continuously. After you turn it on, do not turn it off.
Turn off the power only in the following situations:
v
Instructions in a hardware or software procedure require that you turn off the
power.
v
An IBM technical-support representative instructs you to turn off the power.
v A power outage or emergency situation occurs, see “Restoring power after an
unexpected shutdown” on page 56.
Attention: Except in an emergency, never turn off the power if any amber (needs
attention) LEDs are lit. Correct the fault before you turn off the power. Use the
DS3000 Storage Manager software and the amber LEDs to check the overall status
of the DS3300. All LEDs should be green on the front of the storage subsystem. If
they are not, use the DS3000 Storage Manager software to diagnose the problem
so that the DS3300 will power-on correctly later.

Attention: Turning off and turning on power without waiting for the storage
subsystem disk drives to spin down can damage the drives and might cause data
loss. Always wait at least 70 seconds after you turn off the power before you turn
on the power again.
