Manual No. 771971 4-9
Aborted Installation
With Firmware 4.x, the installation aborted message is displayed when the
BIOS finds that the configuration of the disk drives, as stored in the
NVRAM and configuration on disk, is different from what it sees at boot
time. When this happens, (and a brand new installation is not being
attempted) the cause is often a faulty cable or drive, or a loose connection.
Check all of the connectors, cables, drives, and try to boot. If the error
persists, it most likely indicates a genuine failure and needs to be corrected.
To correct it, boot DOS and run the configuration utility. For more
information, refer to the DACCF Utilities Installation Guide and User
Manual.
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 DOS and run the configuration utility to recover
from the error. For more information, refer to the DACCF Utilities
Installation Guide and User Manual.
System Reboot or Power Down
Status messages may also be available from LED indicators connected to the
DAC960PG. The ‘Write Pending’ indicator is especially important when
preparing to power-down the system.
The DAC960PG is a caching controller with up to 128MB 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 any resetting/rebooting of the system.
If using the 'Write Pending' LED indicator, wait for 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).
