Clear recovery mode

After restoring a storage system configuration, use the Clear Recovery Mode operation to resume I/O on the storage system and return it to normal operations.

Before you begin
  • If you want to return the storage system to a previous configuration, you must restore the configuration from the backup before clearing recovery mode.

  • You must perform validation checks or check with Fujitsu Support to make sure that the restore was successful. After determining that the restore was successful, recovery mode can be cleared.

About this task

The storage system contains a configuration database that includes a record of its logical configuration (pools, volume groups, volumes, and so on). If you intentionally clear the storage system configuration or if the configuration database gets corrupted, the storage system enters recovery mode. Recovery mode stops I/O and freezes the configuration database, which gives you time to do one of the following:

  • Restore the configuration from the automatic backup that is stored in the controller’s flash devices. You must contact Fujitsu Support to do this.

  • Restore the configuration from a previous Save Configuration Database operation. Save Configuration Database operations are performed through the command line interface (CLI).

  • Reconfigure the storage system from scratch.

After the storage system configuration has been restored or redefined and you have verified that all is well, you must manually clear recovery mode.

You cannot cancel the Clear Recovery Mode operation after it starts. Clearing recovery mode can take a long time. Perform this operation only when instructed to do so by Fujitsu Support.

Steps
  1. Select Support > Support Center > Diagnostics tab.

  2. Select Clear Recovery Mode, and confirm that you want to perform this operation.

    This option appears only if the storage system is in recovery mode.
