Manual No. DB11-000028-00 C-3
With Firmware 6.x, if the BIOS displays a mismatch in the Configuration on
Disk (COD) on all drives, then there will be an “install abort”-- no drives
will be installed. Normally this error will not be displayed. If it is, boot and
run RAID EzAssist, the on-board Mylex Disk Array Configuration Utility
(see Chapter 3) to recover from the error. For more information, refer to the
RAID EzAssist Configuration Utility User Reference Guide or RAID
EzAssist Configuration Utility Quick Configuration Guide.
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 eXtremeRAID2000 controller is a caching controller with 32MB,
64MB, 128MB or 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.
If using the 'Cache Dirty' LED indicator, wait three seconds after the LED
has gone off before resetting or rebooting the system (the cache battery
backup may also be used to prevent data loss).
