Save Configuration Information
When restoration of the switchover source site is planned after a failback operation, save the configuration information of the switchover destination site in a location other than the switchover information folder specified in the DR definition file.
For the settings of the DR definition file, refer to "3.3 Manager Installation and Configuration".
Execution of the rcxrepdef command and the rcxstorage command are not necessary.
Example
[Windows Manager]
>Installation_folder\SVROR\Manager\bin\rcxmgrexport -dir C:\Users\Administrator\work\backup\Export <RETURN> |
[Linux Manager]
# /opt/FJSVrcvmr/bin/rcxmgrexport -dir /root/work/backup/Export <RETURN> |
For details on the rcxmgrexport command, refer to "B.1 rcxmgrexport".
Release Resources
For Active-Active operation
Physical servers used for switchover need to be released from the operation of the switchover destination site using one of the following methods.
When manually releasing servers used for switchover from pools
Stop services operating on the physical servers used for switchover.
When the physical OS is operating, shutdown the physical servers.
When being operated as VM hosts, do not shut them down.
For L-Servers operating on the VM hosts, delete or migrate the servers to VM hosts other than those used for switchover.
For details on deletion, refer to "8.3.17 Reconfiguration Page" in the "User's Guide for Tenant Administrators CE".
For details on migration, refer to "17.7 Migration between VM Hosts" in the "User's Guide for Infrastructure Administrators (Resource Management) CE".
When spare servers are set for the stopped servers, release the setting.
Release the physical servers from the physical L-Servers. Or delete the physical L-Servers.
For details on how to release the physical servers from the physical L-Servers, refer to "17.8 Allocating and Releasing Resources to L-Servers" in the "User's Guide for Infrastructure Administrators (Resource Management) CE".
Unregister the physical servers stopped in step a or VM hosts from the resource pool.
When releasing servers used for switchover by deleting tenants
Identify the physical servers used for L-Platforms/L-Servers in the tenants to be deleted or VM hosts, using the GUI or the CLI.
When the physical OS is operating on the physical servers identified in step a, shutdown the physical servers. When being operated as VM hosts, do not shut them down.
Clean up the tenants to be deleted.
Execute the rcxadm config cleanup -tenant command to clean up the tenants to be deleted on the switchover destination site.
When executing the cleanup command (rcxadm config cleanup), add the -predr option and the -deluser option.
- Conditions for -predr Option Addition
Virtual L-Server Switchover (VM Guest) | -predr Option |
|---|---|
Switched over | Added |
Not switched over | Not added |
- Conditions for -deluser Option Addition
Directory Service Information | -deluser Option |
|---|---|
Shared among sites | Not added |
Not shared among sites | Added |
Information
When the -predr option is added to the cleanup command (rcxadm config cleanup), it unregisters the virtual L-Server resources deleted from managers and VM guest information linked to the resources from the VM management software.
This operation is necessary for synchronization of information on VM management software and Resource Orchestrator, when using the virtual L-Server switchover (VM guest) method.
When the -deluser option is added to the cleanup command (rcxadm config cleanup), it deletes the user resources deleted from managers and user information linked to the resources from directory services.
When directory services are shared between sites, deleting user information from directory services disables recovery of the deleted user information, so ensure users are not deleted.
Note
When tenants are deleted using the rcxadm config cleanup command, cloning images used for L-Server deployment in the tenants will be unregistered from resource pools. To continue using the cloning images, register them to resource pools again.
Execute the following procedure, when using servers that have not been used as physical L-Servers in the switchover destination site as physical L-Servers for switchover
Execute the rcxadm server list command.
[Windows Manager]
>Installation_folder\SVROR\Manager\bin\rcxadm server list <RETURN> |
[Linux Manager]
# /opt/FJSVrcvmr/bin/rcxadm server list <RETURN> |
For details on the rcxadm server list command, refer to "3.11 rcxadm server" in the "Reference Guide (Command/XML) CE".
Execute the following procedure for any servers for which a value is given in the SERVER item of the rcxadm server list execution results, within the servers used for physical L-Server switchover.
Delete the target server from the ROR console server tree.
Register the target server in the ROR console server tree.
In this case, do not register the agent.
For Active-Standby operation
In either of the following cases, execute the following procedure from steps 1 to 3.
When performing site switchover
When performing tenant switchover for the first time
Stop all operations of the switchover destination site.
When performing site switchover and either of the following conditions are satisfied, it is not necessary to perform steps 2 and 3.
There are no physical L-Servers that are switchover targets on the switchover source site
None of the physical servers that are switchover targets are already used as physical L-Servers on the switchover destination site
Execute the following command to clean up the configuration information of the entire switchover destination site.
When executing the cleanup command (rcxadm config cleanup), add the -predr option and the -deluser option on the same conditions as in "When releasing servers used for switchover by deleting tenants".
Example
When performing physical/virtual L-Server switchover (VM host/VM guest), and the directory service information is not shared among sites
[Windows Manager]
>Installation_folder\SVROR\Manager\bin\rcxadm config cleanup -deluser <RETURN> |
[Linux Manager]
# /opt/FJSVrcvmr/bin/rcxadm config cleanup -deluser <RETURN> |
When performing virtual L-Server switchover (VM guest), and the directory service information is shared between sites using Active Directory
[Windows Manager]
>Installation_folder\SVROR\Manager\bin\rcxadm config cleanup -predr <RETURN> |
[Linux Manager]
# /opt/FJSVrcvmr/bin/rcxadm config cleanup -predr <RETURN> |
Point
When the cleanup target L-Servers are in Unknown status, only the management information of managers is cleaned up. As the entities of the VM guest inventory are not deleted, manually delete the VM guest inventory from the VM management software, after the managed servers are recovered.
When the automatic collection of switchover information is enabled, performing cleanup disables the setting.
Refer to "4.2.18 Exporting Configuration Information and Resuming Automatic Collection of Switchover Information [Switchover Destination Site]" to enable the setting when necessary.
Execute the following procedure when using servers that have not been used as physical L-Servers in the switchover destination site as physical L-Servers for switchover
Execute the rcxadm server list command.
[Windows Manager]
>Installation_folder\SVROR\Manager\bin\rcxadm server list <RETURN> |
[Linux Manager]
# /opt/FJSVrcvmr/bin/rcxadm server list <RETURN> |
For details on the rcxadm server list command, refer to "3.11 rcxadm server" in the "Reference Guide (Command/XML) CE".
Execute the following procedure for any servers for which a value is given in the SERVER item of the rcxadm server list execution results, within the servers used for physical L-Server switchover.
1. Delete the target server from the ROR console server tree.
2. Register the target server in the ROR console server tree.
In this case, do not register the agent.
