Creating an unencrypted auxiliary storage pool

Use this information to create an unencrypted basic auxiliary storage pool (ASP) and add disk units to the ASP. You can create multiple ASPs at a time. You can assign disk units to a new ASP.

Do things in the right sequence:

  • If you want to have device parity protection for the disks that you are adding, you should start device parity protection before you create an ASP.
  • If you do not want to have device parity protection for the disks that you are adding, you should initialize and format the disk units before you create an ASP.
  • You should plan how you want to add the new disk units to each ASP before you begin this procedure.

To create an independent ASP, you must use IBM Navigator for i or the Configure Device ASP (CFGDEVASP) command. For more information, see Configuring independent disk pools.

To create an unencrypted basic ASP, follow these steps:

  1. 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.
    4. Select option 3 (Add units to ASPs) on the Work with ASP Configuration display.
    or from the System Service Tools (SST) menu, follow these steps:
    1. Select option 3 (Work with disk units).
    2. Select option 2 (Work with disk configuration) on the Work with Disk Units display.
    3. Select option 2 (Add units to ASPs) on the Work with ASP Configuration display.
  2. On the Add Units to ASP display, enter 1 (Create unencrypted ASPs) to create one or more ASPs. 
                              Add Units to ASPs

Select one of the following:

   1. Create unencrypted ASPs
   2. Create encrypted ASPs
   3. Add units to existing ASPs
  3. On the Specify New ASPs to Add Units to display, enter the ASP number (2 through 32) for each disk unit that needs to be added to a new user ASP. This display lists all the disk units that are not configured. 
                        Specify New ASPs to Add Units to     

Specify the new ASP to add each unit to.

    Note: If you are performing a complete system restore, all the disk units on the system might not report in right away. Verify that the number of disk units displayed matches the number of disk units physically attached to the system. If they do not match, wait a few minutes and press F5 (Refresh) until all of the disk units report in.
    1. If you require more than one ASP, type an ASP number next to each disk unit that you want to configure.
      Number 1 is reserved for the system ASP. You can enter a number from 2 to 32. Numbers 33 to 255 are reserved for independent ASPs.
    2. After you complete all units, press Enter.
  4. The Confirm Add Units display shows what the entire system configuration will be when you add the units. Verify this configuration against your planned configuration. 
                                  Confirm Add Units   

Add will take several minutes for each unit.  The system will 
have the displayed protection after the unit(s) are added.   

Press Enter to confirm your choice for Add units. 
Press F9=Capacity Information to display the resulting capacity.
Press F10=Confirm Add and Balance data on units.
Press F12=Cancel to return and change your choice.

  5. You can press F9 (Resulting capacity) to see how the change will affect your disk utilization.
    You are shown the Resulting Capacity display:
                                  Resulting Capacity   
The configuration change that you requested would result in the
 following ASP capacities.

    1. Press Enter or F12 (Cancel) to return to the Confirm Add Units display.
  6. If you are satisfied with the configuration, press the Enter key to add the disk units to the ASP.
    If you want to make changes, press F12 to return to step 3.

    Adding units can take from several minutes to several hours. During that time, you are shown the Function Status display.

                                    Function Status   

You selected to add units. 









                                     5 % Complete
    The system updates the display periodically.
    Note: You can press F16 to return to the Use Dedicated Service Tools (DST) menu if you have other tasks to perform. However, you cannot perform any disk configuration tasks or end DST until the system has finished adding disk units.

    The time it takes the system to add units depends on the type, model, and size of each unit being added and the ability of the system to do multiple adds at the same time.

  7. If you have no other tasks to perform, end DST or SST.
  8. If you created the user ASP (encrypted or unencrypted) using SST, you must perform a normal IPL to use integrated file system objects on the ASP. If you used DST to create the user ASP, you do not need to perform this IPL.
