A.2 Removing or Replacing Hard Disks
The effect of removing hard disks from your storage system or disk failure varies, depending on
the disk configuration you chose when you configured the system and the current state of the
existing disks.
For example, in a linear configuration, when you remove a disk or a disk fails, the data
associated with that disk is no longer available, but the data on all the other disks remains
available.
In a RAID configuration, the effect of disk removal/failure varies, depending on the RAID level
and whether the RAID is in a normal or degraded state. You can determine the effect of disk
removal/failure by looking at the Hotplug Indicator on the Disks page. If this indicator is GREEN,
disk removal/failure will have no effect on the RAID. If this indicator is YELLOW, disk
removal/failure will cause RAID degradation, but you will still be able to access all the data. If
the indicator is RED, disk removal/failure will cause the entire RAID to fail.
For example, in a RAID 5 configuration, all the disks are YELLOW. Removing any one of them
will cause the RAID to be degraded, but all the data will still be available. However, after you
remove one disk, all the other disks become RED, since removing any one of them at this point
