Step 4: Change the DASD CONFIG File So That It Lists the Correct Extents for the CP Object Directory

You must change the DASD CONFIG file to reflect the new location of the CP object directory so that you or other directory managers do not inadvertently allocate a new minidisk over the area you just allocated. Simply covering the area with a placeholder minidisk is not sufficient because subsequently scratching or moving that minidisk can cause CP system failures.

1. Enter the following:

   vmsecure config dasd
   

2. Find the EXTENT record containing the new allocated area and change it to so that it correctly represents the new CP area. Verify a fixed CP extent covers the new area.

   If the area you just created is in the middle of one extent, split the extent into three to isolate the CP area. For example:

   EXTENT beg end
   EXTENT beg *      <=== new CP area
   EXTENT beg end
   

   If the newly allocated area begins or ends the current extent, split the extent in two so that the new CP area is isolated. For example:

   EXTENT beg end
   EXTENT beg *      <=== new CP area
   

3. Save the changes and close the DASD CONFIG file.
