Dot Hill Systems II 200 FC Drive LED Status, Correcting SES or PLD Firmware Version Conflicts

Note – To test that the LEDs work, using a paper clip, press and hold the Reset button for 5 seconds. All the LEDs should change from green to amber when you perform this test. Any LED that fails to light indicates a problem with the LED. When you release the Reset button, the LEDs return to their initial state.

6.2.1Drive LED Status

The drive LED color changes based on array events. For example, when a media scan is performed, to indicate an event is taking place, the drive LEDs blink green for the physical drives that compose the logical drive that is being scanned. The following table lists the events that influence the drive LED status.

Table 6-3Drive LED Status

LED Status	Event	Description
Solid green	No error	A drive is working as expected.
Blinking green	Media scan	A logical drive is created, or the controller is
		reset, and the default media scan command,
		which automatically starts and runs continuously,
		has not been stopped.
Blinking green	Drive activity	A drive is processing I/O.
Amber	Drive fault	A drive fails.
Amber	Identify	The SANscape CLI set led command is run,
		or the firmware application, “Flash All Drives”
		option is used.

Note – The media scan feature sequentially checks each physical drive in a selected logical drive, block by block, for bad blocks. Whenever media scan is running on a drive, its front-panel LED flashes green. It is normal for almost all front-panel drive LEDs to flash green unless media scanning is terminated. For more information about the media scan feature, refer to the SANnet II Family RAID Firmware User’s Guide.

6.2.2Correcting SES or PLD Firmware Version Conflicts

When you replace an I/O controller, the new controller might have a version of SES or PLD firmware different from the other controller in your array. If this mismatch occurs, when you install a controller you hear an audible alarm and see a blinking amber event LED, and an SES event message is sent.
