Backing up and restoring the system configuration
You can back up and restore the configuration data for the clustered system after
preliminary tasks are completed.
Configuration data for the system provides information about your 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 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.
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 have not removed any hardware since the last backup of your
configuration.
v
No zoning changes have been made on the Fibre Channel fabric which would
prevent communication between the Storwize V7000 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.
