Export/Delete Panic Dump

Overview

"Panic Dump" is the action of outputting (dump) memory information when an error (panic) occurs, and also the name of the output information itself. This function exports and saves the memory information of the Controller Module that is stored in the panic dump data, in a segment size specified by the user. An exported panic dump can be stored on a floppy disk or hard disk, or sent by E-mail.

Panic dump is used to analyze the cause of a firmware abnormality or hardware error.

Caution

  • This function cannot be used when there is no panic dump to be exported in the storage system.

  • If one user performs the setting operation while another user is downloading a panic dump, a timeout occurs and the setting operation may be stopped due to an error.

  • Up to two panic dumps can be stored in a single CM.

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

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