Some important notes to be aware of are below:

  • The disk size shown in the examples in this document may be different from yours, depending on the model you receive. This does not affect any of the messages other than the size.
  • RAID disks must be the same size, no greater or smaller. This is because of RAID1 mirroring. If they are not the same size, the rebuild LED does not come on because it is not the correct size.
  • It is best practice to have both disks of the same manufacturer and model.
  • If you replace one disk, rebuilding begins. If the source disk (the one that was not replaced) is then removed before rebuilding is done, you risk losing data.
  • If a disk fails, a "degraded" message alert appears in the syslog.
