Export/Delete Log

Overview

This function exports and saves the storage system maintenance information (log) in accordance with user-specified time settings.

An exported log can be stored on a floppy disk or hard disk, or sent by E-mail.

Also, users can select a log segment size to suit the destination it is to be saved.

Exported Maintenance Information

  • The storage system log includes "internal log" and "configuration information".

    • Internal log

      Detected errors, warnings, and traces

    • Configuration information

      Configuration information exported from the storage system

Caution

  • If a storage system is used in a Unified Storage environment, the storage system log and the NAS Engine log (CM#0/CM#1) are stored in the same file.

  • The internal log and configuration information cannot be exported separately.

  • When exporting of the log is complete, save the log file immediately.

  • The various pieces of maintenance information are combined together, compressed, and then segmented into the user specified segment size before being exported.

    Special tools to read these logs are required.

  • In a Unified Storage environment, when log files are exported while the storage system is in a high-load state, an error may occur due to a timeout. If an error occurs and exporting fails, perform the log export again in a low-load state.

  • If logs saved in the storage system are no longer required, click the [Delete] button to delete the logs. Make sure to backup any necessary data before proceeding.

  • Even after using this function to delete a log, the event log remains in the storage system. To delete the event log, use the [Display Event Log] function.

  • When logged in with Admin or SecurityAdmin role, the [Delete] button is not displayed. Only exporting is executable.
