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.
Caution
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 all activity stops
before resetting, rebooting, or powering off the
system.
The AcceleRAID 170LP controller is a caching controller with 16MB
(fixed) of cache memory. When the system reports that a write command
was completed, data may still be in the cache waiting to be written to the
disk drives.
