Method to preserve install the Work load Partitions

This idea can be implemented for system wpars on AIX as follows:
1. This idea provides an option for the users during wpar creation if they want to preserve the system wpar creating.
2. This idea will create an LV for storing the list of WPARS created with preserve option Eg------ WPARS.

reserve add this LV name entry in the /etc/


3. We will also provide an option say WPARs preserve install during Base OS installation in which case we preserve the wpars during installation.
4. on selection of "WPARs Preserve install", following sequence of steps will be performed.

. The preserve.list file is used and as per that the user LV's are retained along with the User data inside it.

In case of
shared wpars the file systems that are preserved after preserve install are: /wpars/
/wpars/

/home
/wpars/

/tmp
/wpars/

/var

Private wpars the file systems that are preserved after preserve install are : /wpars/
/wpars/

/home

/tmp
/wpars/

/var
/wpars/

/usr
/wpars/

/opt

Then recreate the wpar with the same name as the directory created above in step 3 with

  reserve option. Since the preserved filesystems are used, the wpars are re...
