How to Manage Disk Error (Changing Disks)
Whenever any of the disks goes into abnormal (e.g. disconnected from the HDD tray) or error
status, you can observe it from (1) Event List on Live view (2) RAID setting page.
The failure of disks might or might not result in recording disruption because different RAID
type has different tolerance level toward disk failures. In XNR-4200 RAID system tolerates no
disk failure in RAID 0; one disk failure in RAID 1, 5 and 10.
Please do the following when the any of the disks appears error:
1. Shut down the device, remove and insert the error disk(s) again, then start the device,
and go to RAID settings page to check the disk and RAID status.
2. If the disk remains “Error” status, please do the following according to RAID status:
Note1: When doing the replacing of disks, please make sure the device has been shut down.
Note2: Please use a new disk with at least the same capacity of other drives.
