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
register a warning stating that
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.
