3.4.10 How to power off/on all disk drives manually
The "RQST ON" for Power Supply is defined in the bit5, byte3 of the "Power
Supply control element" in the SES-3 specification. Clear the bit to power
off all disk drives. Set the bit to power on all disk drives. Please install the
software package "sg3_utils" on your host computer, and have a SAS HBA
and a cable to connect your host with the expander. We use Linux for
example.
