Follow the instructions on the dialog to recover from the startup error.

Follow the instructions on the dialog to recover from the write error.

How to Recover from a Configuration File Corruption Error

The only action you can take initially is to select OK because the current configuration files cannot be recovered. Selecting OK will replace the configuration files and reset them to empty files. This results in the Enterprise Management Window displaying no devices, reflecting an empty management domain. After selecting OK, you are given an opportunity to perform an automatic discovery to add devices back to the management domain and rebuild your files. You have the following two choices:

Description and Procedure

Use alternate configuration files

Description

Use alternate configuration files: either a backup copy of your configuration files, or configuration files from another storage management station.

Procedure

1

Select No at the Automatic Discovery dialog.

2

Exit the Enterprise Management Window.

3

Copy the backup files from the alternate directory to the directory specified in the error dialog.

4

Restart the Enterprise Management Window.

5

Verify the devices displayed and, if necessary, use the Add Device pull-down menu option to add any devices that are missing.

Rebuild configuration files

Description

If you do not have backup copies of the configuration files, you will have to rebuild your management domain from scratch using one of the two alternatives listed in the procedure column.

Procedure

Either:

  • Select Yes if you want to perform an automatic discovery to repopulate the management domain.
  • Select No if you want to manually add the devices back to the management domain using the Add Device pull-down menu option.
