HP StoreEver Ultrium Tape Drives - Manual (Page 25)

5 Troubleshooting
General
If problems occur during the operation of HP StoreOpen Standalone or the underlying LTFS utilities,
entries may be made in the system log (either Application or System, depending on the nature of
the problem). The Source may be shown as LTFS or as FUSE4WinSvc, again depending on
exactly what the problem was.
If there is a problem with tape drive interaction, HP StoreOpen Standalone will attempt to create
a snapshot of the drive’s internal state at the time of failure. A snapshot may also be taken at
unmount time. This will be stored in the log directory specified by the Configuration tool (by default
this is \ProgramData\Hewlett-Packard\LTFS\). These files are not otherwise used by HP
StoreOpen Standalone and you can safely remove them from the system, if they are not needed
for troubleshooting. Note that the software only keep the ten most recent snapshots, deleting older
logfiles as necessary.
HP StoreOpen Standalone requires the LTO tape drive to be powered up and connected to the
system. This can be verified using the Windows Device Manager. If the tape drive is not shown,
then check cabling, power, and so on. HP StoreOpen Standalone will not be able to operate until
the drive is detected.
Similarly, the Windows driver (hplto.sys) must be installed and associated with the tape drive
before HP StoreOpen Standalone can communicate with it. You can install the driver from the
CD-ROM that shipped with the drive, or download it from hp.com.
Errors during configuration
Ensure that no other application is using the tape drive. If another application has control of the
tape drive when the configuration tool attempts to create a mapping, you may see one or more
of the following error messages:
•
An error occurred while checking the drive status. Please try again.
•
Operation failed, failed to get exclusive access. Device may be
busy.
•
Drive is inaccessible, The parameter is incorrect.
In each case, a typical resolution is to find and close the other application that is accessing the
tape drive. Other questions to consider are:
•
Is the drive is connected and visible in Device Manager?
•
Has the user the administrative privileges required to perform the operation?
If the configuration utility determines that the current cartridge is not formatted for use with LTFS,
a question is displayed, asking you if you wish to format before proceeding. If you answer NO
(do not format), the mapping will be created but the cartridge will not be formatted, and so will
not be accessible. At this point you must either format the cartridge (starting the FormatWizard
manually) or else eject the cartridge and replace it with one that is already formatted for LTFS.
Explorer windows not refreshing
When the contents of the cartridge are altered by one of the Wizard utilities, any open Explorer
windows may be closed automatically (for example if the format is removed from a cartridge).
However, in some cases the Explorer window may not be updated, even though a refresh was
requested by the software. In this case you need to refresh the window manually (F5 or
View
→Refresh).
