This section explains the HBA address rename settings.
Use the following procedure to configure HBA address rename settings.
Point
The following procedure is not necessary when creating physical L-Servers using HBA address rename for I/O virtualization.
Only the HBA address rename setup service is necessary.
Refer to "Chapter 6 Settings for the HBA address rename Setup Service" in the "Setup Guide CE".
The HBA address rename function allows the admin server to control the WWNs set on a managed server's HBAs. Since the admin server carried over these settings when performing maintenance on or switching managed servers, it is not necessary to set the storage side configuration again.
Use of the HBA address rename function requires registering specific settings for each managed server in advance.
Note
The HBA address rename function is not available if ServerView Deployment Manager is used on the admin LAN. For details, refer to "I.2 Co-Existence with ServerView Deployment Manager" in the "Setup Guide CE".
For servers which already have server switchover configured, when configuring or changing HBA address rename, the following conditions must be met:
Primary servers with HBA address rename configured
Spare servers with the server switchover method HBA address rename configured
For any servers that do not meet these conditions, cancel any existing recovery settings before enabling the HBA address rename function on a server.
HBA address rename and VIOM cannot be used together within the same chassis.
1. Storage Settings
Refer to "10.2 Configuring the Storage Environment" in the "Design Guide CE"to configure the storage.
When altering the configuration of a storage device already used by active servers, ensure those servers are powered off before performing any configuration changes.
2. Settings for the HBA address rename Function
On the ROR console server resource tree, right-click the target server (or the physical OS or VM host on the server), and select [Modify]-[HBA Address Rename Settings] from the popup menu.
The [HBA Address Rename Settings] dialog is displayed.
Define the following settings:
Specify the WWNN value provided by the "I/O virtualization Option".
The admin server generates WWPNs automatically from the values that are input into the WWNN and the number of HBA ports.
Specify the following values according to the system configuration.
To create a single-path configuration, specify "1".
For details, refer to "Figure 5.4 Procedures for Single-path Configurations".
To create a multi-path configuration, specify "2".
However, it is necessary to specify "1" during installation of the operating system. Specify "2" and reconfigure HBA address rename settings after setting up the multi-path driver.
For details, refer to "Figure 5.5 Procedures for Multi-path Configurations".
Figure 5.4 Procedures for Single-path Configurations
Figure 5.5 Procedures for Multi-path Configurations
Example
For a server with two ports, WWNs could be configured as follows.
WWNN value provided by "I/O Virtualization Option": 20:00:00:17:42:51:00:00
Values to set in the [HBA address rename settings] dialog
"WWNN" value 20:00:00:17:42:51:00:00
"HBA port number" on board: 2
Values actually set by the admin server on the HBA (WWPNs are generated automatically)
WWNN value for ports 1 and 2 of the HBA : 20:00:00:17:42:51:00:00 WWPN value for HBA port 1 : 21:00:00:17:42:51:00:00 WWPN value for HBA port 2 : 22:00:00:17:42:51:00:00
Information
WWN settings are applied to managed servers during server startup.
Note
With HBA address rename, as WWNs are allocated to the I/O addresses of HBAs in descending order, the order may not match the port order listed in the HBA.
For details, refer to "C.2 WWN Allocation Order during HBA address rename Configuration" in the "Design Guide CE".
Check the [Restart the server] checkbox if the server is to be restarted.
Information
Select server restart in the following cases.
When installing an operating system immediately after performing the above settings
Insert the operating system installation CD in the target server and select server restart. Once the server has been restarted, its WWN settings are applied and the operating system installation starts.
When an operating system is already running (if changing storage settings)
Click [OK] to restart the target server and apply its WWN settings.
The server restart is not required in other cases. The WWN that has been set is enabled at the next restart.
Click the [OK] button.
Information
When using a server without an OS, the resource name displayed on the server resource tree is the same as that of the physical server.
Restart the HBA address rename setup service.
The HBA address rename setup service must be running to use the HBA address rename function.
For details on how to configure these settings, refer to "Chapter 6 Settings for the HBA address rename Setup Service" in the "Setup Guide CE".
