The Web monitor reports higher-level information about a RAID that
has a missing or bad Flash module. Figure 32 above shows the RAID
information generated by removing the same Flash drive as shown in
Figure 31. In this case, the removed module causes the RAID to be
degraded, meaning the RAID cannot tolerate another Flash module
error without data loss – but the RAID is still usable.
