Parity error on scsi hardware

oudoubah · 05-12-2006, 07:32 AM

Hello,

I've a server with an Adaptec 29160 (module AIC7XXX) scsi card.
I've plugged a storage library (ADIC FastStor 2) on it.
Linux version : Red Hat EL 3.2 - kernel version 2.4.21-27

After an electric interruption, i can't see the optical drive on the library.

dmesg said :

Code:

scsi1 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 6.2.36

The library has been changed by a new one.

Do you have any clue to help me to solve this problem?

Thanks!
