Storwize V7000 system. You must regularly back up your file systems and your
application data by using the appropriate backup methods.
You can maintain your configuration data for the system by completing the
following tasks:
v Backing up the configuration data
v Restoring the configuration data
v Deleting unwanted backup configuration data files
Before you back up your configuration data, the following prerequisites must be
met:
v No independent operations that change the configuration for the system can be
running while the backup command is running.
v No object name can begin with an underscore character (_).
Note:
v 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.
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.
Contact the IBM support center to help you prepare the Storwize V7000 Unified
system to do the restoring of the system configuration on the control enclosure.
The configuration restore procedure is designed to restore the information about
your block storage configuration, such as block volumes, local Metro Mirror
information, local Global Mirror information, storage pools, and nodes. All the data
that is written to the block volumes is not restored.
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.
