HP Storage StoreOpen Standalone for Microsoft Windows User Guide

Mount options
In most circumstances the default options are suitable and you do not need to change them. However
for flexibility you can modify them if you wish. The options are as follows:
Mount read-only If you select this option, the cartridge contents are readable but cannot be
modified. This provides a software write-protect mechanism; the same effect can be achieved
using the “hardware write protect tab on the tape cartridge.
Remount at system start-up The normal behavior is to configure the service so that it
automatically restarts when the system boots up. Unselect this checkbox if you do not want
this to happen (for example, if this is a temporary setup where the tape drive will be removed
after the system is shut down).
Advanced options this opens a further window where you can adjust less common options.
NOTE: Some of these options may have a noticeable impact on performance and in general
should not be changed.
Support ticket folder: This is the location where drive logs are stored. These logs are
generated on each unmount and whenever an error is detected. The application will keep
the ten most recent logs and automatically delete any older logs. These logs may be useful
to HP support personnel but otherwise can be ignored.
Enable verbose logging: This is not required in normal operation and you should only
use it when requested by HP support personnel, as it will have an adverse effect on
performance.
Enable extended verbose logging: This adds a further level of detail to logfile entries.
Thumbnails: When Windows encounters a folder full of files, it attempts to build thumbnails
to represent the content of each file. This is not desirable in an LTFS volume, because it
may take many minutes or even hours to generate the thumbnails. So by default HP
StoreOpen Standalone tells the operating system that the volume is in the offline state,
which prevents automatic thumbnail creation. You can turn this off if desired, but be
aware that it will have a severe effect on the time needed to open and browse folders.
Index capture: This option allows you to keep a copy of the latest index from tape on
the local disk. Enable the check box and enter the path to the folder where you would
like to keep the index file after the tape is unmounted.
Index updates: This allows you to control when indexes are written to tape; see “Index
updates (page 9) for more details.
Index partition usage: The LTFS format allows for data files to be written in the index
partition, which if used carefully may improve access times for frequently-used files.
However, in general you should leave this setting in its default state.
Index updates
Accessing data stored on tape relies on an up-to-date index being available. HP StoreOpen
Standalone offers three different mechanisms for updating the copy of the index stored on tape.
The default setting is to write a copy of the index to tape periodically while writing data; the index
is written every five minutes. You can change the time interval to every minute. This method of
index update reduces the window of exposure to power-loss events, since there will be an index
on tape no more than five minutes old (if using the default interval).
The second option is to write the index to tape only when a volume is removed. In normal operation
this is sufficient, since the LTFS usage model requires the volume to be unmounted after use, so
there is always a valid index. However, if power is removed from the drive without unmounting,
