A possible problem that might occur during the multiple reboot processes of an operating system deployment on a server is an improper setting for the state variable that controls the overall installation. The improper setting can occur when an error occurs that does not stop the installation.
The sample task sequence templates in the IBM Deployment Pack provide for multiple reboots back to USB or PXE and use a computer variable to track the current boot stage in the process.
The computer variable determines which groups or steps are run during each phase of the deployment. If an error occurs during a task sequence, this variable is not automatically reset. When an error occurs, your task sequence might not restart from the beginning or even the current phase of deployment.
Remove the computer variable for any computer that has failed the task sequence to make sure that the computer restarts the sequence from the beginning.
You can reset the computer variable by performing the following procedure.
