is limited.

It is unlikely but possible for multiple Flash modules to fail in a single
RAID. If it happens, the system will turn the RAID offline.
System Status: FAIL
Errors: Flash Array
Offline The front panel display will
show a system failure. The
system should not be exercised
while in a failed state.
If a RAID is put offline, all Flash modules in that array will have their
front LED illuminated red.
