HP StoreEver Ultrium Tape Drives - Manual (Page 33)

Check the Command View TL Device Analysis Service log for
received tickets
As tickets are received by Command View TL, entries are made in the das_[0..9].log (Device
Analysis Service) file which is found in the log folder in the Command View TL install directory:
C:\Program Files\Hewlett-Packard\Command View TL\log
There can be multiple log files starting with das_0.log and working up to das_9.log. This is done
to limit disk usage and you must identify which of these is the most recent file (sort by Date Modified)
to find the most recent log entries.
The log is very detailed and records a large number of low level steps, but if you can see the drive
tickets referenced in that file, they are being received by Command View TL.
Check the Command View TL Device Analysis log for rejected
tickets
Each received ticket is checked for completeness and for any corruption. The most common case of
rejection is when a ticket is pulled from a drive that hasn’t had a tape loaded since power on because
there is no tape-related data. Incomplete or corrupt tickets are rejected to avoid inconsistencies in the
database.
If a ticket is rejected, it is recorded in the da.log file (Device Analysis) which is found in the log folder
in the Command View TL install directory:
C:\Program Files\Hewlett-Packard\Command View TL\log
The fields that are incomplete or corrupt are listed in the log entry, which might help isolate the root
cause of the problem.
If a ticket is rejected it is moved into a holding folder so that it can be viewed with L&TT and checked:
C:\Program Files\Hewlett-Packard\Command View TL\log\tickets
