    Dear Sun Managers,
           I have installed Veritas Netbackup on Solaris 8. The 4 storage
    unit is connected to the server by SCSI.
    But all the operations are hanging. I found the error logs " Parity
    Error" on /var/adm/messages.

    Can some one tell how can I the " Parity Error" problem.
