Excluding volumes from automatic assignments
The Current Volume Configuration panel provides line command eXclude
to allow you to make exceptions to automatic assignment. Line command
eXclude has different uses, based on the scope of automatic
assignment, as listed below:
- For the ALL setting, you use line command eXclude to select volumes for removal from the work configuration (the volumes are not actually removed from the work configuration until after you enter the CReate command to create the configuration). The dialog does not use excluded volumes for data set assignments. When you create the new configuration (through the CReate command) and display it again, excluded volumes do not appear in the panel.
- For the NEW setting, you use line command eXclude to make a volume ineligible for the assignment of new data sets; the volume remains in the work configuration and its existing data set assignments are left unchanged. However, as in the ALL setting, the volume is removed from the Current Volume Configuration panel because no new data sets will be assigned to it. When you create the new configuration and display it again, excluded volumes do not appear in the panel. (However, if you exit the Recommended System Layout function and re-enter it, the volume is again included in the Current Volume Configuration panel.)
- For the PARTIAL setting, you use line command eXclude to make a volume's data sets eligible for reassignment. When you create the new configuration, the excluded volume is removed from the work configuration. When you enter a CReate command, an excluded volume will also be removed from the Current Volume Configuration panel because the volume's data sets will be reassigned to other volumes. When you redisplay the Current Volume Configuration panel, the excluded volume does not appear in the Current Volume Configuration panel.
If you exclude a volume from the work configuration and then later change your mind, you can restore the volume to the Current Volume Configuration panel. If you have not yet created the new configuration (through the CReate command), you can restore the volume to the panel by exiting the Recommended System Layout option and re-entering it. The configuration will be displayed as it was when you previously entered the Recommended System Layout option.
If you have already created the configuration, choose one of following
approaches:
- In the ALL and PARTIAL settings, the volume is gone. Take one
of these actions:
- Add the volume to the configuration and assign data sets to it
- Rename one of the new volumes to the volser you want
- Recreate the configuration (re-enter the CReate command) and try again.
- In the NEW setting, the volume will reappear when you exit the Recommended System Layout option after creating the new configuration.
