AMCC 720-0138-00 manual Backup DCB read error detected, Battery voltage is normal

Chapter 9. Troubleshooting

0043 Backup DCB read error detected

This message will be sent when the controller sees a latent error in the backup Disk Configuration Block (DCB). A scrubbing activity will be started to repair any sector errors on getting this error. An effort is made to read the backup DCB even when the primary DCB is successfully read. When an error occurs here, this is a latent error that needs to be addressed before any future errors so this DCB is re-written with the primary copy to rectify the errors found.

If this error occurs, we recommend verifying the unit. See “Starting a Verify Manually” on page 72.

0044 Battery voltage is normal

The Battery Backup Unit measures and evaluates the battery pack voltage on a continuous basis. If the voltage falls outside the acceptable range then comes back within the acceptable range, this message will be posted to the host.

0045 Battery voltage is low

The Battery Backup Unit measures and evaluates the battery pack voltage on a continuous basis. If the voltage is below the warning threshold, this message will be posted. When this event happens, the Battery Backup Unit is still able to backup the 3ware RAID controller, but you should replace the battery.

0046 Battery voltage is high

The Battery Backup Unit measures and evaluates the battery pack voltage on a continuous basis. If the voltage is above a warning threshold, this message will be posted. When this event happens, the Battery backup Unit is still able to backup the 3ware RAID controller but you should replace the battery.

0047 Battery voltage is too low

The Battery Backup Unit measures and evaluates the battery pack voltage on a continuous basis. If the voltage is too low to operate, this message will be posted. This indicates that the battery pack must be replaced. The Battery Backup Unit becomes not ready and is unable to backup the 3ware RAID controller.

0048 Battery voltage is too high

The Battery Backup Unit measures and evaluates the battery pack voltage on a continuous basis. If the voltage is too high to operate, this message will be posted. The Battery Backup Unit becomes not ready and is unable to backup
