identify [device_list] [start | stop]
Identify one or more devices by blinking their LED.
The default action is to start the LED blinking and return to the prompt. The LED

array identify stop command is given for that device.
To identify all of the disks in an array, use the array identify command.
info [device_list]
Output information about some or all devices. (You can specify which devices by
entering a parameter for device_list.)
This command is identical to the device manage device info command (see
Device manage device commands) when only one device is specified.

local_device_list.
