Backing Up The System Configuration Using The Cli - IBM Storwize V7000 Unified Series Problem Determination Manual

To restore the data on the block volumes, you must restore the application data
separately from any application that uses the volumes on the clustered system as
storage. The file volumes are not restored. You must restore the file module
configuration and the file systems separately. Therefore, you must have a backup
of this data before you follow the configuration recovery process.
Before you restore your configuration data, the following prerequisites must be
met:
v You have the Security Administrator role associated with your user name and
password.
v You have a copy of your backup configuration files on a server that is accessible
to the system.
v You have a backup copy of your application data that is ready to load on your
system after the restore configuration operation is complete.
v You know the current license settings for your system.
v You did not remove any hardware since the last backup of your configuration.
v No zoning changes were made on the Fibre Channel fabric which would prevent
communication between the Storwize V7000 Unified and any storage controllers
which are present in the configuration.
v For configurations with more than one I/O group, if a new system is created on
which the configuration data is to be restored, the I/O groups for the other
control enclosures must be added.
Before you begin, hardware recovery must be complete. The following hardware
must be operational: hosts, Storwize V7000 Unified, drives, the Ethernet network,
and the SAN fabric.

Backing up the system configuration using the CLI

You can back up your configuration data using the command-line interface (CLI).
Before you back up your block storage configuration data, the following
prerequisites must be met:
v No independent operations that change the configuration can be running while
the backup command is running.
v No object name can begin with an underscore character (_).
v If the ID of the object is different from what is recorded in the current
configuration data file, the default object names for controllers, I/O groups, and
managed disks (MDisks) do not restore correctly.
v 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.
The backup feature of the svcconfig CLI command is designed to back up
information about your system configuration, such as volumes, local Metro Mirror
information, local Global Mirror information, managed disk (MDisk) groups, and
nodes. All other data that you wrote to the volumes is not backed up. Any
application that uses the volumes on the system as storage, must back up its
application data using the appropriate backup methods.
You must regularly back up your configuration data and your application data to
avoid data loss. If a system is lost after a severe failure occurs, both configuration
