This section explains how to configure WWN settings for integration with ETERNUS SF Storage Cruiser.
Specifying HBA WWNs, storage WWNs, and AffinityGroup for ETERNUS SE Storage Cruiser enables configuration of the zoning settings of Fibre Channel switches and storage unit host affinity. When performing switchover on managed servers, using the WWN settings enables the admin server to automatically change settings of storage devices.
Use of this function requires registration of specific settings for ETERNUS SF Storage Cruiser in advance. Fibre Channel Switches and storage units connected to managed servers must be registered on ESC.
Note
WWN settings for servers and HBAs are not performed by this function.
Configuration cannot be performed for managed servers that are configured as spare servers or are used as spare servers. Therefore, perform this configuration before configuring spare servers.
Use the following procedure to configure the WWN settings.
When changing the current WWN information, configure the new WWN information after deleting Fibre Channel Switch zoning and storage unit host affinity in the currently configured WWN information.
In the ROR console server resource tree, right-click the target physical server, and select [Modify]-[WWN Settings] from the popup menu.
The [WWN Settings] dialog is displayed.
Perform the following settings:
Select the following values according to the system configuration.
Procedures for Single-path Configurations
Specify "1" for HBA ports.
Procedures for Multi-path Configurations
Select the number of multi-paths for HBA ports.
However, it is necessary to select "1" during installation of the operating system. Select the number of paths and reconfigure HBA address rename settings after setting up the multi-path driver.
[OVM for SPARC]
When using an IO domain in an OVM for SPARC environment, select the numbers of the HBA ports used in the control domain and the IO domain. If the primary server and the spare server share disks, exclude the numbers of HBA ports for the shared disks.
Enter or select the WWPN of an HBA collected from physical servers.
When using a multi-path configuration, enter the values of the HBAs and the corresponding CAs of servers in the same order, based on the values in"8.1.6 Settings when Switching Over Fujitsu M10/SPARC Enterprise Servers" in the "Design Guide CE".
If the primary server and the spare server share disks, do not enter the HBA ports for the shared disks.
Select WWPNs of storage CA and AffinityGroup.
Select hyphens ("-") to keep spare servers inactive.
Also, select a hyphen ("-") when deleting Fibre Channel Switch zoning and storage unit host affinity in the configured WWN information.
When using a server on which an agent is registered as a spare server, the server must meet all of the following conditions:
When the WWPN of the target CA is the same value as that of the primary server
When the AffinityGroup value is different from the value of the primary server
When agents are not registered on ETERNUS SF Storage Cruiser
Note
When using the storage affinity switchover method, if a hyphen ("-") is selected, the storage path settings will be deleted.
Click the [OK] button.
Perform configuration or deletion of Fibre Channel Switch zoning and storage unit host affinity based on the configured WWN information. When the target operation server is registered on ESC, the status should be as below:
Configuration
The server should be turned on
Deletion
The server should be turned off
When configuration and deletion of Fibre Channel Switch zoning and storage unit host affinity have been already executed, no operations will be performed on the devices.
Note
For WWPN value specification, check that the value does not overlap with the WWPN used for HBA address rename or VIOM. If the same WWPN is used, there is a chance data on storage units will be damaged.
When configuration or deletion of Fibre Channel switches or storage units performed, a warning dialog is displayed. Make sure that there are no problems in the settings, then click the [OK] button.
If the target CA is not displayed, confirm the status of the following settings:
ESC is correctly registered on Resource Orchestrator.
Fibre Channel switches and storage units are correctly registered.
Only one access path is configured on ESC for each CA of an HBA.
