Resetting an overflowed user auxiliary storage pool (ASP) during an initial program load (IPL)

You can learn how to reset an overflowed user ASP during an IPL.

Sometimes you are not able to find all the overflowed objects in a user ASP. If you have taken the steps described in Resetting an overflowed user auxiliary storage pool (ASP) without an initial program load (IPL) topic and the user ASP is still overflowed, you can perform a manual IPL to reset the user ASP. Perform the following tasks:

Ensure that you have enough space to reset the overflowed user ASP. Follow these steps:
1. Type STRSST. You are shown the System Service Tools (SST) menu.
2. Select the option to work with disk units.
3. Select the option to display disk configuration.
4. Select the option to display disk configuration capacity.
  You are shown the Display Disk Configuration Capacity display:
```
                     Display Disk Configuration Capacity                                                

 --Protected--  --Unprotected-- 
ASP  Unit  Type  Model  Threshold  Overflow   Size  %Used    Size  %Used  
1                           90%    No            0   0.00%   1400   8.22%
1          9332   400                            0   0.00%    200  17.97%
       2   9332   400                            0   0.00  
2                                  Yes           0   0.00%    200  99.99%
       8   9332   200       90%                  0   0.00%    200  99.99% 
```
  This display shows whether any ASPs are in overflowed status.
5. Press F9 (Display ASP Overflow information) to display the overflow amount and the additional amount of storage that is needed in the ASP to recover the overflowed objects.
```
                    Display ASP Overflow Information
 Overflow      ----Amount Needed to Recover---- ASP  Threshold    Amount
               To Capacity     To Threshold
  2                   90%           14                 0               0  
  3                   90%           25                25              45 
```
6. If the amount in the To Capacity field is greater than zero, the ASP will still be overflowed when the recovery completes.
  There is not enough free space in the user ASP to contain the overflowed data.
7. If you do not have enough space, repeat the instructions in step 5 in Resetting an overflowed user ASP without an initial program load IPL topic to free more space.
To put your system in a restricted state, follow these steps:
1. Before putting your system in a restricted state, ensure that all users are signed off and all jobs are ended.
2. To receive notification that the subsystems have ended, type the following command and press the Enter key:
```
CHGMSGQ MSGQ(QSYSOPR) DLVRY(*BREAK)
        SEV(60)
```
3. To end all subsystems, type the following command:
```
ENDSBS SBS(*ALL) OPTION(*CNTRLD)
       DELAY(600)
```
  Note: For the delay parameter, specify a number of seconds that allows your system time to bring most jobs to a normal end. On a large, busy system, you might need a longer delay.
A message is sent that indicates that the procedure for ending subsystems is in progress. A final message is sent when the system is in a restricted state.
Perform a manual IPL and access dedicated service tools (DST):
Use this procedure to start DST. If the IPL or Install the System menu is already displayed, start with step 5 in Task 1–Accessing dedicated service tools topic.
1. Ensure the keystick is in the system unit control panel.
2. Place the system in manual mode.
3. Power off the system:
```
PWRDWNSYS OPTION(*CNTRLD) DELAY(600)
          RESTART(*YES) IPLSRC(B)
```
  Note:
  If you are sure that no jobs are running on your system, you can specify OPTION(*IMMED) when you power off the system. Otherwise, specify a delay time that is sufficient to allow jobs to end normally.
4. When the IPL completes, the IPL or Install the System menu appears.
```
                          IPL or Install the System

   Select one of the following: 
            1. Perform an IPL
            2. Install the operating system
            3. Use dedicated service tools (DST)
            4. Perform automatic installation of the operating system
            5. Save Licensed Internal Code 
```

Select option 1 (Perform an IPL).

You are shown the Disk Configuration Attention Report:

                    Disk Configuration Attention Report
 
Type option, press Enter.
     5=Display Detailed Report
Press F10 to accept all the following problems and continue.
The system will attempt to correct them.

     Overflowed ASPs

If you type 5 in the Option field, the following display is shown, listing the User ASPs that are overflowed.

                         Recover Overflowed User ASP
 
The following user ASPs are overflowed.
 
 
ASP
 2
 3

Press the F10 key to request recovery of the overflowed user ASPs.
The recovery takes place during the storage management recovery phase of the IPL. The operation takes from several minutes to a few hours, depending on the number of objects on the system and the amount of data to be recovered.
When the IPL of the system is complete, the Sign On display is shown.
Sign on and verify the results by checking the messages in the QSYSOPR message queue.
