For x86 systems, you can use ipmitool to manipulate the led state
(ipmitool sunoem led ...). On older galaxy systems, you can only set the
fail LED ('io.hdd0.led'), as the ok2rm LED is not physically connected
to anything. On newer systems, you can set both the 'fail' and 'okrm'
LEDs. You cannot change the activity LED except by manually sending the
'set sensor reading' IPMI command (not available via impitool).
For external enclosures, you'll need a SES control program.
Both of these problems are being worked on under the FMA sensor
framework to create a unified view through libtopo. Until that's
complete, you'll be stuck using ad hoc methods.
