Deleting an auxiliary storage pool

When you delete a user auxiliary storage pool (ASP), the status of all the disk units that are assigned to the ASP becomes nonconfigured. Any data that is in the ASP is deleted.

The normal procedure is to remove all objects from the ASP before you delete the ASP. You can do this either by moving the objects to a different ASP or by deleting the objects. If you delete an ASP that has objects in it, those objects are marked by the system as damaged or destroyed.

You cannot delete ASP 1, which is the system ASP and holds the operating system.

To delete a user ASP, follow these steps:

If you are not already using dedicated service tools (DST), perform a manual initial program load (IPL) to start DST.
From the Use Dedicated Service Tools (DST) menu, follow these steps:
1. Select option 4 (Work with disk units).
2. Select option 1 (Work with disk configuration) on the Work with Disk Units display.
3. Select option 3 (Work with ASP configuration) on the Work with Disk Configuration display.

Select option 2 (Delete user ASP) on the Work with ASP Configuration display and press the Enter key.
