Rename the FSPM Host

Follow these instructions to rename a host where Oracle FS Path Manager (FSPM) is installed and to ensure the new host name change is updated in the Oracle FS System configuration information.

FSPM installs a service which monitors status and manages the Control Path connections to an Oracle FS System. When the FSPM service running on a host makes a Control Path connection to a Pilot, it sends the hostname which FSPM discovered from the host to the Oracle FS System. That hostname is used as the name of the host entry in the Oracle FS System Services. If you want to change the hostname of a SAN host that is running FSPM, use the following sequence of steps to create an FSPM host entry in the Oracle FS System Services with the new name and the same LUN mappings as the old FSPM host entry.

Note: If you rename a host without going through this process, the LUN mappings to the host are lost. You will not be able to access the Oracle FS System LUNs from the host until the LUN mappings are recreated. This process preserves the LUN mappings from the original host name to the renamed host name.

The following information describes how to rename a host where FSPM is installed.

From the Oracle FS System Manager (GUI), ensure that one of the host initiators is connected to the Oracle FS System. Follow these steps:
1. From the GUI, select SAN > Storage > Hosts.
2. Under the Host Name locate the host to be renamed.
3. Under the Controller-Initiator Connectivity verify that Connected is displayed for one of the connections.
Stop the FSPM service. Follow information provided in this document.
Review the existing LUN mappings for the host you are renaming before deleting the host. From the GUI, select SAN > Storage > Host-LUN Mapping to review the LUN mappings to the host you are deleting.
From the GUI, select SAN > Storage > Hosts to select the host you want to delete.
From the GUI select SAN > Storage > Hosts > Actions > Delete Host and delete the host entry with the old host name. The Delete SAN Host dialog is displayed.
1. When the Delete SAN Host dialog is displayed, make sure the Delete mappings and initiators is not checked. This preserves the associated LUN mappings to the host. Select OK to delete the SAN Host.
2. You can also delete a SAN Host using the Oracle FS CLI. Review the Oracle Flash Storage System CLI Reference for further information.
From the host operating system, rename the host.
Start the FSPM service (also referred to as the daemon) following the instructions in this document.
Result:
Once the FSPM is started, FSPM logs into the Pilots and sends a message that includes the new host name. The Oracle FS System creates an FSPM host entry with the new host name and transfers the initiators and LUN mappings associated to the host. (These values were preserved when the host was deleted.)
From the GUI, select SAN > Storage > Host-LUN Mapping to verify the LUN mappings are restored to the renamed host.
