HP Linear Tape File System Software - Manual (Page 29)

• MANAGEMENT_STATION_IP – the IP address of the Command View TL management station
• MANAGEMENT_STATION_PORT – the port number of the Command View TL management station.
Normally 8099 unless the port number has been changed using Command View TL.
• POLLING_INTERVAL – Verify that tickets are transported frequently enough to match your
mount/unmount model. The default is that all outstanding tickets pulled by the HP LTFS driver will
be sent every hour. Tickets are not removed from the HP LTFS ticket store directory when they are
sent to Command View TL.
• HP LTFS TICKET STORE DIRECTORY – By default. HP LTFS writes the tickets to the /var/logs/
directory on Linux and to the $HOME/Library/Logs/LTFS/ directory on Mac. The directory
can be changed by the HP LTFS user. The TapeAssure LTFS service configuration must match the
ticket store directory used by HP LTFS.
Check the TapeAssure LTFS service log for sent tickets
When the TapeAssure LTFS service sends a ticket to Command View TL is makes a log entry in the
SA-TapeAssure_Service
log file, which is located in the installation directory. The entry includes
the ticket name, which references the drive serial number and time when the ticket was created by
HP LTFS.
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. 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
