In addition to the error correct features built into the Flash module,

the Flash modules are protected from a complete Flash module failure

by a RAID configuration. If only a single module fails in a RAID, all

data in the array will be preserved. You should replace the bad Flash

module right away. If the system detects a bad Flash module, it will

note the bad module by illuminating the red LED on the front of the

module.

System Status: WARN

Errors: Flash Module

Degraded

 The front panel display will

one or more modules have

been degraded. A degraded

module functions correctly, but

a degraded array cannot

tolerate another Flash module

failure without data loss.

You can also get information about the state of the Flash modules from

the Web monitor.
