ReadyNAS Ultra Hardware Manual
Replacing a Failed Disk
In the case of a failed disk, the unit provides email alerts and status messages about the
need to replace the disk. In addition, as a visual reference, each ReadyNAS disk tray
includes an LED that turns amber when the disk in the tray fails.
ReadyNAS supports hot-swap bays, so there is no need to power it down when a disk fails.
To replace the failed disk:
1.
Locate the amber LED on the disk tray to identify the failed disk.
2.
In the same way as when you add a disk, pull the disk tray pull release switch.
The disk tray handle pops out.
3.
Pull out the disk tray, and replace the failed disk.
Make sure that the hard disk connectors face the interior of the disk bay when you
reassemble the disk.
4.
Slide the disk tray back into the unit and secure the handle.
The volume automatically synchronizes with the new disk in the background. This could
take several hours depending on the disk size. The ReadyNAS can continue to be used,
although access will be slower until the volume synchronization finishes. You are notified
by e-mail when the process is complete.
