Backing Up And Restoring The System Configuration - IBM Storwize V7000 Unified Problem Determination Manual

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 block system
and the objects that are defined in it. The backup and restore functions of the
svcconfig command can back up and restore only your configuration data for the
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
v No object name can begin with an underscore character (_).
Note:
v The default object names for controllers, I/O groups, and managed disks
v All other objects with default names are renamed during the restore process. The
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:
operations as complete). For any VMs, which are targets of recent clone
operations, complete the following tasks.
– Perform data integrity checks as is recommended for conventional volumes.
– If clones do not function as expected or show signs of corrupted data, take a
fresh clone of the source VM to ensure that data integrity is maintained.
running while the backup command is running.
(MDisks) do not restore correctly if the ID of the object is different from what is
recorded in the current configuration data file.
new names appear in the format name_r where name is the name of the object in
your system.
