Error Messages

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 RAID EzAssist Configuration Utility User Reference Guide, available on CD-ROM, or RAID EzAssist Configuration Utility Quick Configuration Guide.

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 three 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).
