HBA address rename is enabled by setting the WWN of the managed server HBA from the admin server when a managed server is powered on. This WWN is kept by managed servers until powered off.
However, a managed server will not be able to receive its assigned WWN unless it can communicate with the admin server. If communication with the admin server fails, because of problems on the admin server or a failure of the managed server's NIC, the managed server will not start up properly as its HBA will not be set up with the correct WWN.
This can be avoided by using the HBA address rename setup service, which acts as a backup service in case of communication issues between the admin server and managed servers. This service, which must run on a server other than the admin server, can set up managed servers HBAs WWNs in the same way the admin server does.
This service must be running in order to use HBA address rename.
Use the following procedure to configure the HBA address rename setup service.
Open the [HBA address rename setup service] dialog.
[Windows]
Select [start]-[All Programs]-[Resource Orchestrator]-[HBA address rename setup service].
[Linux]
Execute the following command while in a desktop environment.
# nohup /opt/FJSVrcvhb/bin/rcxhbactl start& <RETURN> |
The [HBA address rename setup service] dialog is displayed.
Define the following settings:
The status of the service is displayed. "Stopping" is displayed if the service is not running, and "Running" is displayed if the service is running.
Enter the IP address of the admin server.
Enter the port number that is used to communicate with the admin server. The port number at installation is 23461.
If the "rcxweb" port number of the admin server is changed, specify the number that has been changed.
Displays the latest synchronization time.
This is the last time this service synchronized its data (managed server settings) with that of the admin server.
Click one of the following buttons:
To Start This Service:
Click <Run>.
To Stop This Service:
Click <Stop>.
To Cancel the Operation:
Click <Cancel>.
To verify that this service is running properly, power off the admin server and confirm that managed servers can still start up normally.
Note
The following remarks apply to this service.
Keep it "Running" at all times.
Start it on only one server for each admin server.
OS administrator privileges are required to start and stop this service.
Do not operate it on the server where the manager is installed.
The admin server and the servers configured with the HBA address rename setup service must be placed in the same segment of an admin LAN.
[Windows]
In a clustered Manager configuration, this service can be run on the standby node. In this case, configure the startup settings following the procedure in the Manager Cluster Operation Settings.
After performing settings for this service following the procedure for cluster operation settings, it is not necessary to perform the above procedure for starting and stopping.
For details, refer to "Appendix B Manager Cluster Operation Settings and Deletion" in the "Installation Guide CE".
[Linux]
In a clustered Manager configuration, this service can be run on the standby node. In this case, the above procedure should be skipped as configuration and control of the HBA address rename setup service is handled during setup of the cluster system.
For details, refer to "Appendix B Manager Cluster Operation Settings and Deletion" in the "Installation Guide CE".
