Raid Issue ________________________________

system was flashing front panel amber LED & beeping.  This apparently was occurring
for months.  The hardware trouble-shooting guide from the MB manual did not identify
the issue. There were no fault lites on any fans, PSU nor front bay drives.
Removed the LSI Raid interface -- fault notications stopped -- implied a problem
with the RAID Array.  Ctrl-G early in boot sequence gets one into the RAID configuration
GUI.  This indicated Slot 11 have no Physical Drive ( there was a drive in the slot)
The drive was marked off-line & removed logically. Physically removed & replaced the
drive & the raid look ok.  
The system did not see a file system on the raid ( /dev/sda)
"parted" the drive 00 created partition 1 as all available space.
mkfs -f /dev/sda1
mount /dev/sda1 /dstore
