Changing Virtual I/O Server settings

You can change the Virtual I/O Server (VIOS) settings that are specified in a system template by using the Hardware Management Console (HMC). You can add or remove VIOS, change the properties of the VIOS, or change the resources that are assigned to the VIOS.

1. Choose one of the following navigation options depending on the interface type of the Hardware Management Console (HMC):
   • If you are using an HMC Enhanced interface, complete the following steps:
     1. In the navigation area, expand Systems Management > Servers.
     2. Select a server and click Templates > Template Library.
   • If you are using an HMC Enhanced+ interface, complete the following steps:
     1. In the navigation pane, click the HMC Management icon .
     2. Click Templates and OS Images, or click Template Library.
2. Click the System tab and select the system template that you want to change.
3. Click Action > Edit. The Template Detail page is displayed.
4. To change the Virtual I/O Server (VIOS) settings, click the Virtual I/O Servers tab. Select the VIOS that you want to rename. You can specify the name in the VIOS Name field. To add a VIOS, complete the following steps:
   1. Click the Add VIOS tab.
   2. In the General tab, you can specify the name for the VIOS in the VIOS Name field.
