To Uninstall an OS Update on a Server Group

Before You Begin

• Disable monitoring for the managed servers. This action is required only if you want to avoid the fault notifications if the servers reboot after an OS update uninstallation. See To Disable Monitoring for a Managed Server or a Managed Server Group in Sun N1 System Manager 1.3 Discovery and Administration Guide for details.

• Ensure that the OS monitoring feature is supported on the managed servers. This action provides the necessary support to uninstall OS updates. See To Add the OS Monitoring Feature in Sun N1 System Manager 1.3 Discovery and Administration Guide for details.

Steps

1. Log in to the N1 System Manager.

   See To Access the N1 System Manager Command Line in Sun N1 System Manager 1.3 Discovery and Administration Guide for details.

   Caution –
