RAIDar LED Descriptions

The first column (LED) lists the status that informs you if the ReadyNAS device is in normal
operating mode, or if it is in a warning or failure condition.
The other columns display device-specific status, which tells you exactly what devices might
need attention.

Description
No disk or device is attached.
Device is in normal operating mode.
The device has failed or needs attention.
This disk is a spare disk on standby. If a disk fails, this disk will take
over automatically.
This disk is waiting to resync to the RAID volume.
If the LED is blinking, this disk is currently resyncing.
During the resync process, volume is in degraded mode; performance
is affected by the resync process, and another disk failure in the
volume will render it dead.
The volume has encountered multiple disk failures and marked dead.
However, the ReadyNAS has blocked it from being marked dead if
someone accidentally pulled out the wrong disk during runtime.
If the wrong disk was pulled out, shut down the ReadyNAS
immediately, reconnect the disk, and power on the ReadyNAS. If you
reconnect the disk during runtime, the ReadyNAS marks it as a newly
added disk and you will no longer be able to access the data on it.
A lengthy background task such as a system update is in progress.
