6.4.2.9.4. System Details ⇒ Provisioning —
This tab and its subtabs allow you to schedule and monitor kickstarts and to return your system to a previous state. Kickstart is a Red Hat utility that allows you to automate the reinstallation of a system. Snapshots keep a record of every change to a Provisioning system and allow you to "undo" those changes at will. Both features are described in the sections that follow.
This subtab is further divided into Session Status, which tracks the progress of previously scheduled kickstarts, and Schedule, which allows you to configure and schedule a kickstart for this system.
This subtab allows you to schedule the selected system for kickstart. Choose from the list of available kickstart profiles, select a time for the kickstart to begin, and click the Schedule Kickstart and Finish button to begin the kickstart. You may first alter kickstart settings by clicking the Advanced Configuration button.
You must first create a kickstart profile before it appears on this subtab. If you have not created any profiles, refer to Section 6.4.9.3, “Create a New Kickstart Profile” before scheduling a kickstart for a system.
If you have scheduled a kickstart, this subtab shows the progress of the kickstart. The provided details include the kickstart profile used, its state, the next action and the number of requested packages. Kickstarts that do not complete within approximately two hours are marked Kickstart Failed. The page refreshes itself periodically, or you can force a refresh using your browser's controls.
Snapshots enable you to roll back the system's package profile, configuration files, and RHN settings. Snapshots are captured whenever an action takes place on a Provisioning-entitled system. The Snapshots subtab lists all snapshots for the system , including the reason the snapshot was taken, the time it was taken, and the number of tags applied to each snapshot. To revert to a previous configuration, click the Reason of the snapshot taken and review the potential changes on the provided subtabs, starting with Rollback.
Each subtab provides the specific changes that will be made to the system during the rollback:
group memberships
channel subscriptions
installed packages
configuration channel subscriptions
configuration files
snapshot tags
When satisfied with the reversion, return to the Rollback subtab and click the Rollback to Snapshot button. To see the list again, click Return to snapshot list.
Provides a means to add meaningful descriptions to your most recent system snapshot. This can be used to indicate milestones, such as a known working configuration or a successful upgrade. To tag the most recent snapshot, click create new system tag, enter a descriptive term in the Tag name field, and click the Tag Current Snapshot button. You may then revert using this tag directly by clicking its name in the Snapshot Tags list. To delete tags, select their checkboxes, click Remove Tags, and confirm the action.
