Step 2: Find Enough Free Space on the Current CP–Owned Volume for the Entire Directory

As a rule, enough space is about double the amount of space you have just calculated in Step 1. This free space must be on one volume, but it can contain multiple extents and does not need to be contiguous. However, you can improve performance by allocating one contiguous area.

1. To find free space on the volume that currently contains the CP object directory, enter the following:

   vmsecure map volser free
   

   volser

   The volume that contains the CP object directory (the volume listed in the CP QUERY ALLOC DRCT output).

   This command displays the free space on DASD volume ESA240.

   The command response in the following example displays the availability on 3390–type volume ESA240:

   *VOLUME: ESA240     TYPE: 3390          UTILIZATION: 83%
   ALLOCATION   SIZE   STARTING    ENDING  USAGE INFORMATION
   *FREE*       75     1           75      *FREE*
   *FREE*       54     190         243     *FREE*
   *FREE*       23     650         672     *FREE*
   

2. If the output of this command indicates that there is no free space or not enough free space available, move a minidisk of the correct size to another volume to make the space available.

   Check how much free space is available after you move a minidisk. Use the MAP command to do so. If there is still not enough space, move as many minidisks as necessary to free up the space you need.

3. Calculate the range of the new free space. These numbers are required when you are ready to format and allocate the new extent:
   • For a CKD device, the starting and ending cylinder numbers of this new free space define the range
   • For an FBA device, by the starting and ending page numbers of this new free space define the range

   To calculate the starting page number, use this formula:

   

   To calculate the ending page number, use this formula:
