21 BackPak H4.00 Troubleshooting & Messages
Here are the possible “other processes” that can open the Windows disk file:
- A script configured in the Data store is still executing, backing up or restoring this
file.
- Another tool configured to duplicate the image of virtual volumes is processing
the file
- An Antivirus running in the VTC is configured to scan the images of virtual
volumes; note Antivirus are normally configured to avoid the scan of virtual
volumes.
- Two BackBox domains load the same virtual volume by accessing the same
Windows disk file.
ABORT TASK reported by the VTC Emulator
On severe error conditions in the VTC Tape Emulator, for example a failure to write
the image of virtual volume into the Data store, the tape application will often abort.
The error recovery in the SCSI protocol is then reported by the VTC Tape Emulator in
the MS-Windows Event Viewer, “Virtual Tape Controller” log, by this kind of
message:
10/16/2010 2:05: 48 AM VTC Emula tor (FC) Informa tion
None 5095 N/A STLTTAPEP2 V irtual Tape Device Po rt00-
Target00-Lun00 REINITIALIZE after an ABORT TASK
The first thing is to browse the NonStop EMS messages, the Windows Event Viewer
logs, and the Windows log produced by the VTC (VTLog.log or FCLog.log) to analyze
the error condition and to fix it.
ABORT TASK is a just a log of error recovery that does not need special consideration
for an FC connection.
For a SCSI copper connection, it is recommended to, as soon as possible, stop all
tape devices in the NonStop SCF, re-boot the VTC server and restart the tape
devices in SCF.
Error triggering a NonStop utility
NonStop utilities, mainly SCF, MEDIACOM and CLIMCMD, are occasionally started by
the Domain manager when no public SPI interface is available. There are currently
two such cases:
- In the UI, VTC Configuration page, configuration of virtual devices by Tabs
“Add Devices Automatically” and “Refresh”.
- During the load of a tape volume catalogued in DSM/TC, the media type is
updated in DSM/TC to match the media type configured in the Volume group
of BackPak.
The most common symptom is the Domain manager times out waiting for the result
in the OUT file of the utility. EMS shows error messages such as:
E3427 Error nn opening <file-name> containing result…
E3404 Timeout, more than <nn> seconds .. waiting for file <file-name> …
