Parity error/ Can't read from disk

[Ayman Altounji]

Hi

All of a sudden my server will not boot. Hardware configuration error.

DAAD gave me the following information, What can I do ?

Did the Server crash , before problem started ?

Did you apply a ROMPAQ , add anything new to the Server ?

Have you tried re-running the System Configuration Utility , Array Configuration Utility ?

Have you tried upgrading the firmware on the Smart 2/P ?

RIS Copy Mismatch errors are a common problem with older versions of the DAAD and ADU utilities... What version are you using? Do you know what firmware the controller is using?

This type of error is usually not the cause of a boot issue. When does the configuration error come up (OS or POST)? Do you get other errors when starting the system?

I have used the latest patches from Compaq to analyze the problem.
At server start the array controller reports no problem. When NT loader is checking hardware its stops and displays a warning message.
"Windows NT cannot start due to hardware diskconfiguration error...."

When i use the DAAD it reports an Array controller error with a red! on the controller. I can access the partition with a DOS bootdisk and Partition Magic and even resize the partition.

The server is configured with 3x 4,3 Gb disks in RAID5.
