Hello,
Perform the following steps to resolve the issue:
1) Verify the following SCSI BIOS settings:
Set the tape drive SCSI ID as low as possible, avoiding 0 or 1, which
are usually reserved for bootable devices.
Set INITIATE SYNC NEGOTIATION for the SCSI ID of the
tape drive to off
Set INITIATE WIDE NEGOTIATION to off for controllers
with a wide bus
Set MAXIMUM SYNC TRANSFER RATE to the lowest possible
value for the SCSI ID of the tape drive
DISCONNECT must be enabled for all tape drive SCSI ID's
Set SCSI PARITY CHECKING to off
* WARNING:
The Parity Checking adjustment is for diagnostic use only and should never
be left disabled during production backups! Read the detailed explanation!
VERITAS Software can not be held liable for data corruption due to parity
checking being disabled.
2) Reduce the total number of devices on the controller.
3) Update the SCSI Controller Driver and firmware
4) Update the Tape Drive firmware
5) Separate the tape device from a controller which also has hard drives
connected to it.
6) Check the Windows NT/2000 System and Application Event Logs for
warnings/errors. Event ID 7, 9, 11, & 15 in the System Event Log usually
indicates that there is a hardware problem
-- Install the latest Veritas deviec drivers using following link:
http://seer.support.veritas.com/docs/273853.htm
-- Perfomr a test backup and verify the result.
- In order to isolate the cause of the issue, stop all Backup Exec
services, perform a backup job with Windows native backup
utility (NTBACKUP) and verify the result. If you are getting the similar
error then it rules out any issue related to Backup Exec.
