be reviewed with the help of the DAC Admin Windows NT software utility
that is installed on the server.
To review errors detected on a RAID hard drive
1 Click the Start Menu.
2 Click Run.
3 Type dacadm.exe .
4 Click OK.
Result: This starts the DACAdmin software utility.
5 Click the Configuration menu.
6 Choose Drive Information on the Configuration menu.
Result: A list of all hard drives connected to the RAID controller appears.
Note: Hard drives marked ONL are online and part of a RAID System
pack.
7 Click on a drive to see a summary of errors.
a. If there are ten or more soft errors per day, replace the drive.
b. Hard errors should not occur during normal operation. Contact your
Nortel Networks customer support representative if errors are
accumulating.
c. Miscellaneous Errors are typically due to cabling or termination
problems on the SCSI bus. Verify jumper settings on all SCSI devices
and ensure that cabling is secure.
d. When the total number of errors reaches 127, the controller marks the
drive DED. DED means offline. The drive must be replaced.
