Troubleshooting Repairing a Degraded Array A • Off: The drive is OK. The white LED means that that there is a locate request currently on the disk drive: • Blinking White: There is a locate request currently on the disk drive (see "Storage Status," on page 6 page on the configuration interface). There can only be one locate request set for a disk drive at one time. • Off: The disk drive is not marked by a locate request. USB LED (Front Panel) • Solid Green: The USB hard/flash drive is connected and is not safe to remove. • Blinking Green: The USB hard/flash drive is connected and is being mounted or unmounted. • Off: There is either no USB hard/flash drive connected to the NSS, or, if connected, the USB hard/flash drive is safe to remove. UPS LED (Back Panel) • Off: There is either no UPS attached to the NSS or the UPS function has been disabled in the System Power page in the configuration interface. • On: A UPS is attached to the NSS and the UPS function is enabled in the System Power page in the configuration interface. For more information about the UPS, refer to the UPS documentation. Repairing a Degraded Array If a RAID level 1, 5, or 10 is in a degraded state (that is, a redundant disk drive has failed), you can replace the failed disk drive(s). (You might be able to use some of the data on a JBOD if there are volumes that do not span across the failed disk. Otherwise, you must rebuild the JBOD after you replace the disk.) If an array with no redundancy has a failed disk drive, you must delete the array, replace the disk drive, and then recreate the array.

Repairing a Degraded Array
If a RAID level 1, 5, or 10 is in a degraded state (that is, a redundant disk drive has
failed), you can replace the failed disk drive(s). (You might be able to use some of
the data on a JBOD if there are volumes that do not span across the failed disk.
Otherwise, you must rebuild the JBOD after you replace the disk.) If an array with
no redundancy has a failed disk drive, you must delete the array, replace the disk
drive, and then recreate the array.
