data. This can be attempted via the <Recover System Procedure> also known as a
Tier 3 (T3) procedure. Restoring the system configuration without attempting to
recover the application data is performed via the <Restoring the System
Configuration> procedure also known as a Tier 4 (T4) recovery. Both of these
procedures require a recent backup of the configuration data.
Perform the following steps to back up your configuration data:
Procedure
1. Back up all of the application data that you stored on your volumes using your
preferred backup method.
2. Issue the following CLI command to remove any temporary working files
created by a previous configuration backup or restore attempt:
svcconfig clear -all
3. Issue the following CLI command to back up your configuration:
svcconfig backup
The following output is an example of the messages that may be displayed
during the backup process:
CMMVC6155I SVCCONFIG processing completed successfully
The svcconfig backup CLI command creates three files that provide
information about the backup process and the configuration. These files are
created in the /dumps directory of the configuration node canister.
The svcconfig backup CLI command creates three files that provide
information about the backup process and the configuration. These files are
created in the /dumps directory of the configuration node canister.
The following table describes the three files that are created by the backup
process:
File name
svc.config.backup.xml_<serial#>
svc.config.backup.sh_<serial#>
svc.config.backup.log_<serial#>
4. Check that the svcconfig backup command completes successfully, and
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.
5. It is recommended to keep backup copies of the files above outside the system
to protect them against a system hardware failure. Copy the backup files off the
system to a secure location using either the management GUI or scp command
line. For example:
Description
This file that contains your configuration
data.
This file that contains the names of the
commands that were issued to create the
backup of the system.
This file contains details about the backup,
including any reported errors or warnings.
