Backing up and restoring the system configuration

You can back up and restore the configuration data for the system after preliminary tasks are completed.

Configuration data for the system provides information about your system and the objects that are defined in it. You must regularly back up your application data by using the appropriate backup methods.

You can maintain your configuration data for the system by completing the following tasks:
  • Backing up the configuration data
  • Restoring the configuration data
  • Deleting unwanted backup configuration data files

Before you back up your configuration data, the following prerequisites must be met:

  • No independent operations that change the configuration for the system can be running while the backup command is running.
  • No object name can begin with an underscore character (_).
Note:
  • The default object names for controllers, I/O groups, and managed disks (MDisks) do not restore correctly if the ID of the object is different from what is recorded in the current configuration data file.
  • All other objects with default names are renamed during the restore process. The new names appear in the format name_r where name is the name of the object in your system.

Before you restore your configuration data, the following prerequisites must be met:

  • You have the Security Administrator role associated with your user name and password.
  • You have a copy of your backup configuration files on a server that is accessible to the system.
  • You have a backup copy of your application data that is ready to load on your system after the restore configuration operation is complete.
  • You know the current license settings for your system.
  • You did not remove any hardware since the last backup of your configuration.

Before you begin, hardware recovery must be complete. The following hardware must be operational: hosts, the enclosure, the Ethernet network, and the SAN fabric.
