Figure 32 – Web Monitor RAID Degraded Detection

WARNING

MAKE CERTAIN THAT FLASH MODULES ARE POWERED OFF BEFORE REMOVING.

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.
