Restoring the system configuration

Use this procedure in the following situations: only if the recover procedure failed,
if the data that is stored on the volumes is not required, or if the files that are
stored in the file volumes by the file modules are not required. For directions on
the recover procedure, see "Recover system procedure" on page 380.
Before you begin
This configuration restore procedure is designed to restore information about your
configuration, such as volumes, local Metro Mirror information, local Global Mirror
information, storage pools, and nodes. The data that you wrote to the volumes is
not restored. To restore the data on the volumes, you must restore application data
from any application that uses the volumes on the clustered system as storage
separately. 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.
If encryption was enabled on the system when it was backed up, then USB devices
need to be present in the system for the Tier 4 (T4) recovery to work. The USB
devices do not need to contain any key material. They are for generation of new
keys as part of the restore process.
About this task
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
for the system and application data is lost. You must restore the system to the
exact state it was in before the failure, and then recover the application data.
During the restore process, the nodes and the storage enclosure will be restored to
the system, and then the MDisks and the array will be re-created and configured.
If there are multiple storage enclosures involved, the arrays and MDisks will be
restored on the proper enclosures based on the enclosure IDs.

examine the command output for any warnings or errors. The following output
is an example of the message that is displayed when the backup process is
successful:
CMMVC6155I SVCCONFIG processing completed successfully.
If the process fails, resolve the errors, and run the command again.
system hardware failure. Copy the backup files off the system to a secure
location; use either the management GUI or SmartCloud Provisioning
command line. For example:
pscp -unsafe superuser@cluster_ip:/dumps/svc.config.backup.*
/offclusterstorage/
The cluster_ip is the IP address or DNS name of the system and
offclusterstorage is the location where you want to store the backup files.
Tip: To maintain controlled access to your configuration data, copy the backup
files to a location that is password-protected.
