Step 2: Find Enough Free Space on a CP–owned Volume for the Entire Directory

As a rule, enough space is about double the amount of space you 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, enter the following:
    vmsecure map * free
    

    This command shows free space on all DASD volumes controlled by CA VM:Secure.

    To find where you have directory space allocated, enter the CP QUERY ALLOC DRCT command. Only one directory area will be listed as active. If more than one DRCT area is allocated, we recommend you delete the inactive areas before continuing. To delete the space, mark it as PERM, using the procedure in Step 10.

    The following example shows a portion of the VMSECURE MAP command response. It displays the availability on 3390–type DASD 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:

    To calculate the starting page number, use this formula:

    This diagram explains the formula for finding free space.

    To calculate the ending page number, use this formula:

    This diagram depicts the formula for finding enough free space.
