This section explains operations which need to be performed in order to be able to perform disaster recovery switchover.
If updating is performed on the primary site, such as resource configuration information to do with an L-Platform deployment, perform the following to collect the information for Disaster Recovery switchover. Collect information either automatically or periodically to ensure the latest configuration information is available.
Export the Required Information from the Primary Site
Export the required information
As a backup in case of failure of the primary site, and where an environment has been constructed on the backup site that can be used for recovery, export the information as explained below. When information is collected automatically, this information is not necessary.
L-Platform Templates
L-Platform Configuration Information
Resource Information
Execution Information of Sample Scripts
Accounting Information
Metering Logs
Usage Charges
One of the following operations is recommended.
When changing the configurations of managed servers, export the information first, and maintain the latest system information
Export regularly, and update the data
Execute the command shown below to collect the information.
[Windows Manager]
>Installation_folder\SVROR\Manager\bin\rcxmgrexport <RETURN> |
For details on the rcxmgrexport command, refer to "A.1 rcxmgrexport".
Export Network Configuration Information
When you change the target network device configuration, keep the latest system configuration by exporting the information.
Execute the command shown below to collect the information.
[Windows Manager]
>Installation_folder\SVROR\Manager\bin\rcxadm netconfig export -file switchover_installation_folder\OtherBackupfiles\networkconfiginfo.xml <RETURN> |
Specify the XML file of the output destination used as the -file option argument so that it will be stored in switchover_information_folder\OtherBackupFiles.
For details on the rcxadm netconfig command, refer to "3.7 rcxadm netconfig" in the "Reference Guide (Command/XML) CE".
Note
Operations such as L-Platform deployment, cancellation, or configuration modifications which change various information, must not be performed during export of information.
If the accounting setting is on, it is recommended to export switchover information every day.
This ensures the exported information of the primary site will be updated with the newest information.
When using VMware as the server virtualization software, note the following regarding execution of rcxmgrexport:
Do not execute rcxmgrexport immediately after performing any operations which move the files of the virtual machines (e.g. VM migration involving changes of datastores, storage vMotion). Be sure to execute rcxmgrexport after the information is reflected on ROR by a regular update.
When a virtual machine is moving a VM host (e.g. vMotion), do not execute rcxmgrexport. Execute rcxmgrexport after such operations are completed.
Confirm Switchover Scope
Perform this procedure when configuring the limitations of switchover scopes.
After executing rcxmgrexport, execute the following commands to confirm that the switchover scope is correct.
rcxmgrexport -drlist : Displays the list of the resources that are switchover targets. rcxmgrexport -drlist -error : Displays the list of resources which use both targeted storage and non-targeted storage for Disaster Recovery, and therefore cannot be switched over. |
Example
> rcxmgrexport -drlist TYPE NAME ---- ---- L-Server /tenant_1/l-server_1 Image /image_1 Image /image_2 > rcxmgrexport -drlist -error TYPE NAME ---- ---- L-Server /tenant_1/l-server_1 |
For details on the rcxmgrexport command, refer to "A.1 rcxmgrexport".
If the displayed switchover targets are not appropriate, check if the limitation of switchover scope is correctly configured. For details on the limitation of switchover scope, refer to "3.3 Manager Installation and Configuration".
Backup the Configuration Files of the Primary Site
Copy the configuration files of the primary site to the backup site, in case the contents of the configuration files are different between the primary and backup sites. Copy the files listed in "Configuration Files for Matching Details between the Primary and Backup Sites" in "2.4 Configuration of the Primary and Backup Sites" into the "OtherBackupFiles" folder in the switchover information folder .
Obtain the Storage Replication Information
Check the corresponding LUNs used to perform storage unit replication for the primary and backup sites.
When "3.7 Configuring Automatic Switchover Information Collection Settings" is performed, this operation is not necessary, because the information is collected automatically.
Create a replication definition file which describes LUN relations.
When using dynamic LUN mirroring storage of ETERNUS, as the target LUNs to be replicated are changed by the deployment or cancellation of L-Platforms, and the addition or removal of disks, create the replication definition file using the rcxrepdef command.
When using a LUN that was created in advance, if the replication definition is created, modified, or deleted by the storage management software, create a replication definition file using the rcxrepdef command.
Example
>Installation_folder\SVROR\Manager\bin\rcxrepdef ccm -local 192.168.0.X -remote 192.168.0.Y -file file1 <RETURN> |
After creating the replication definition file, specify it and create the file to perform mapping of LUNs in the backup site resources from the relation lists during import.
To create this file, execute the rcxstorage command with the -recovery, -mode, and -outfile options specified. Specify "prepare" for the -mode option, and switchover_information_folder\storage_file for the -outfile option.
For details on the switchover_information_folder, refer to "3.2 Creating Switchover Information Folders".
Example
>Installation_folder\SVROR\Manager\bin\rcxstorage -recovery -mode prepare -file file1 -outfile D:\Export\storage_file <RETURN> |
For details on replication definition files, refer to "Replication Definition Files" in "17.1.3 High Availability for Storage Chassis" in the "Operation Guide CE".
For details on the rcxrepdef command, refer to "5.22 rcxrepdef" in the "Reference Guide (Command/XML) CE".
For details on the rcxstorage command, refer to "5.23 rcxstorage" in the "Reference Guide (Command/XML) CE".
Back up Directory Service Information
Back up the directory service information. Back up the information, after performing operations such as registration, modification, or deletion of a user. For the backup procedure, refer to the manual for the directory service product being used.
Back up VM Management Software Information
When not configuring VM management software on a physical L-Server using the physical/virtual L-Server switchover (VM host/VM guest) method, it is necessary to restore the VM management software information during switchover. Therefore, back up the VM management software information as well. For details on how to back up and restore VM management software information, refer to the manual of each VM management software. It is necessary to collect the VM management software information when registering, modifying, or deleting an L-Platform on which a virtual L-Server is deployed.
Back up Firewall Configurations
When configuring a firewall automatically using the auto-configuration function for network devices, it is recommended to use the network device configuration backup command or the management software configuration backup function, and operate as follows:
After configuring auto-configuration of the firewall, back up the configuration and collect the newest configuration.
Back up firewall configurations regularly.
When backing up a firewall configuration regularly, collect the firewall configuration immediately after executing rcxmgrexport, which exports configuration information of Resource Orchestrator, to synchronize the timing of configuration backup. Note that this operation is not necessary for NS appliance.
Reflect Changes of Settings and Back up Configuration Files
After a Disaster Recovery environment is configured, if the settings of the primary site are changed according to "Chapter 8 Changing Settings" in the "Operation Guide CE", the changes of the following settings need to be reflected in the backup site before switching.
"8.2 Settings for Sending Email"
"8.4 Editing Information in the Home Window"
"8.5.1 Settings for Permissions to Change L-Platform Templates"
"8.5.2 Subnet Settings at Segment Editing"
"8.5.3 Settings for the Simplified Reconfiguration Function"
"8.5.4 Distribution Ratio Settings"
"8.5.5 Application Process Settings"
"8.5.7 Edit the License Agreement"
"8.5.9 Default Password Setting for Sent Emails"
"8.5.10 Settings for the Maximum Number of Connections for the L-Platform Template"
"8.6.1 Settings for Tenant Management and Account Management"
"8.6.2 Editing the User Agreement when Registering a User"
"8.7 Accounting Settings"
"8.8 System Condition Server List Settings"
"8.9 Settings for Event Log Output for CMDB Agent"
Back up the following files if they have been modified.
