System Reboot or Power Down
Status messages may also be available from LED indicators connected to the
controller. The Cache Dirty indicator is especially important when preparing
to power-down the system.
The eXtremeRAID 3000 RAID controller is a caching controller with
32MB, 64MB, 128MB and 256MB of cache memory, data may still be in the
cache waiting to be written to the disk drives, when the system reports that a
write command was completed. It is very important to make sure that all data
is written to the disk before rebooting or powering down the system, or you
may lose data. It is always a good idea to wait for 60 seconds or until system
activity stops before resetting or rebooting the system.
