Manual Number 775012 C-3
NVRAM Error
With Firmware 4.x, if the BIOS displays a mismatch between the NVRAM
and the COD, no drives will be installed. Normally this error will not be
displayed. If it is, boot and run the on-board Mylex Disk Array
Configuration Utility (see Chapter 4). to recover from the error. For more
information, refer to the Disk Array Controller Configuration Utilities
(DACCF) Installation Guide and User Manual.
System Reboot or Power Down Messages
Status messages may also be available from LED indicators connected to the
DAC960PG/PJ. The Write Pending indicator is especially important when
preparing to power-down the system.
The DAC960PG/PJ is a caching controller with up to 128 MB 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 15 seconds before resetting or rebooting the system.
If using the 'Write Pending' LED indicator, wait 3 seconds after the LED has
gone off before resetting or rebooting the system (the optional cache battery
backup may also be used to prevent data loss).
