This chapter describes how to define general LTFS-LE system settings. The following topics are included:
Use the System Properties page in the LTFS-LE BUI to set general LTFS-LE system properties.
To access this page, click the Settings tab and then select System Properties from the selection panel.
The System Properties page includes the following settings:
By default, ACSLS automatically pushes LTFS-LE notifications when there are changes to the library or devices. Additionally, you can set an Auto Re-discover value to direct LTFS-LE to query ACSLS for this information.
Enter a value (in minutes) to specify how often LTFS-LE queries ACSLS for updated library and device information. This value must be greater than zero (0). The recommended value is 24 minutes.
In the Resource Timeout field, enter the maximum amount of time (in seconds) that LTFS-LE waits for a volume to be mounted before timing out and issuing a request failure message. This value must be 90 seconds or greater. The recommended value is 300 seconds.
Enter a minimum remaining volume capacity in MegaBytes. Once this watermark is reached, LTFS-LE cannot write additional files to this volume. This value must be 16384 MB or greater.
The DB (database) Backup Path is also displayed.
This path represents the database backup path from both the BUI and crontab, and the global namepsace backup path from the BUI.
The global namespace backup path from crontab is /MetadataBackup.
When you are finished, click Apply. A confirmation dialog box appears, indicating that your input has been validated. Click OK to close this dialog box.
On the System Properties page, click OK to commit your settings.
When a user deletes a file, LTFS-LE deletes the metadata from the LTFS-LE global namespace while the data remains on the physical volume. Then, the next time the volume containing this file is mounted, the file is physically deleted from the volume as a background activity.
The Background File Delete page enables you to specify when this LTFS-LE file deletion is to occur.
To access this page, click the Settings tab and select Background File Delete from the selection panel.
Do one of the following:
In the Start Time field, enter a time for deletion to begin. For example, 3:45 pm.
Click the Select Time icon to select a specific deletion date and time from a calendar.
Under Recurring Frequency, select one of the following options to specify how often this deletion task occurs:
Daily
Weekly
Monthly
Yearly
When the Recur Details dialog box appears, select one of the following:
For a weekly frequency, select an option to indicate the day of the week when file deletion should occur.
For a monthly backup, specify the day of the month when file deletion should occur.
For a yearly backup, specify the day of the year when file deletion should occur. Enter a date in the format mm/dd/yyyy or click the Select Date icon to select the date from a calendar.
Click OK. The Recur Details dialog box closes.
From the Background File Delete page, click Apply. A confirmation dialog box appears, indicating that your input has been validated.
Click OK to close the dialog box.
From the Background File Delete page, click OK. A confirmation dialog box appears, indicating that your background file delete schedule has been successfully set.
Click OK to close the dialog box.
Use the About LTFS-LE page in the LTFS-LE BUI to view the following LTFS-LE component information:
To access this page, click the Settings tab and select About LTFS-LE from the selection panel.

The LTFS-LE BUI System Backup page enables you to schedule a local backup of the LTFS-LE database and shadow namespace to the LTFS-LE server, outside of the LTFS-LE application. You define the server backup location during LTFS-LE installation. Refer to the StorageTek Linear Tape File System, Library Edition Planning and Installation Guide for more information.
To access this page, click the Settings tab and select System Backup from the selection panel.
