Changing a system template

You can change the details that are specified in a captured, or user-defined system template and save the changes in a new system template. You can also overwrite the template by saving the changes in the same template. You can use this template to deploy other systems by using the Hardware Management Console (HMC).

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 Physical I/O settings, click the Physical I/O tab. You can change enable or disable using captured I/O information. Click the Use Captured I/O Information check box to use the captured physical I/O information. When you enable or disable the Use Captured I/O Information check box, the check box is displayed in the read only mode in the Hardware Virtualized I/O tab for the system configuration, and in the Hardware Virtualized I/O tab of the Add VIOS wizard.
