The "RQST ON" for Power Supply is defined in the bit5, byte3 of the "Power
Supply control element" in the SES specification. Clear the bit on Power
Supply Element “DiskPowerSupply” to power off all disk drives. Set the bit
on Power Supply Element “DiskPowerSupply” to power on all disk drives.
We use the software package "sg3_utils" on Linux for example, and have
a SAS HBA and a cable to connect your host with the expander.
