Problem
"An
unknown error occurred" may occur when backing up to tape on a server with
the HP Server Management Agents Software and/or HP
StorageWorks Managements Software installed.
Error

- An unknown error has occurred
Completed
status: Failed
Final error: 0xe00084f4 - An unknown error has occurred.
Final error category: System Errors

code :V-79-57344-34029
Cause
The SCSISTAT_QUEUE_FULL error is
often caused by a conflict with the HP Insight Server Management Agent software
or the HP StorageWorks VDS Hardware Providers for MSA Disk Arrays software.
This condition can be confirmed by running TRACER.EXE and performing a
SCSI trace on the failing hardware. See related documents for more
information on how to use TRACER.EXE.
The following SCSISTAT_QUEUE_FULL error will be
seen on a WRITE6 command
(Figure 1):
Figure 1
The STATUS_DEVICE_NOT_CONNECTED error
may also be caused as the Driver Result (Figure 2):
Figure 2
When
getting the STATUS_DEVICE_NOT_CONNECTED error,
the Device error 1167 is reported
in the adamm.log.
Note:
The SCSI trace in the adamm.log does not report the Driver Result.

Solution
1. Install the latest version of HP
Insight Agents and
test another backup.
2. If the server is Windows 2003,
upgrade to the latest StorPort driver.
3. Run the StorageWorks Library and Tape Tools (L&TT) and run a
100GB backup test.
B. Stop the Backup Exec services.
C. Insert a scratch tape into the
drive. ****Important! This needs to
be a scratch tape as the HP L&TT test will overwrite the data on the tape.
D. Select the drive that you want to test
under the "By Product" tab.
E. Click on the TEST icon at the top of the
window.
F. Drill down to READ/WRITE test in the TEST
GROUP FIELD.
G. Click on the Options button.
H. The Options window will open. You can
double click on the "Amount of data written/read in each phase" and
change the amount of data to the 100 GB.
The
L&TT test will now write 100GB of test data to the drive. If this test
fails, then contact HP Technical Support for further troubleshooting.
4.
Increase BusyRetryCount and test another backup.
Please
refer to TECH163202 to increase BusyRetryCount.
5. Disable the HP Management Agents.
Go to Control Panel > HP Management
Agents, select the Services tab, then move SCSI Information to the Inactive
Agents column. Retry the backup job.
If it still fails, try moving the performance
monitor agent to the disabled column and try the backup again.
6. Disable the following HP services, and
reboot the server and test another backup.
- HP Insight Server Agents
- HP Insight Storage Agents
- HP Insight Foundation Agents
- HP WMI Storage
Providers service
NOTE: Not
all Four services may be present. Only disable what is listed above as
these services conflict with the symantec drivers which are updated for
tape drives.
7. Uninstall the HP StorageWorks VDS Hardware
Providers for MSA Disk Arrays software and test another backup.
This
software is installed on HP Storage Servers by default. This software may not
be listed in Control Panel > Uninstall a program. Please contact HP
Technical Support to uninstall this program.
8. Uninstall the HP Insight Manager software and test
another backup.
9. If there is any third party backup software
which is not in use may block the tape device and may cause conflict. Uninstall
and test another backup.
