IPL the image
Note: Keypoints are shared for all images. If there is something wrong with a
keypoint, that prevents you from bringing a system to NORM, IPL your
loader general file and use the ZIMAG KEYPT RESTORE command to
restore the keypoints you had before you entered the ZIMAG KEYPT MOVE
command. This allows you to come up again on your prime mod.
To use the enabled image, you must perform a hard IPL, choose image selection,
and enter the name of the image.
Note:
Update IPLA on a loader general file
1. If you are IPLing an image that has a different core layout from the
previously used image, IPL with CLEAR to clear the VFA buffers.
2. If the image does not IPL successfully, IPL another image and debug the
problem image.
Use the following sample JCL and complete the following steps to place an updated
version of IPLA on an existing loader general file.
Note: Do this only if you have a loader general file that was previously initialized
and formatted and want to replace only the IPLA component without running
the system initialization process (SIP) to generate the JCL. If you are
creating the loader general file for the first time, see “Initialize and format the
loader general file and online modules” on page 73.

1. Update the JCL with any local job library information.
2. The JCL references IPLA in the Linux HFS that it was built in. You must change
the referenced HFS to point to the binary mount HFS name, which contains
IPLA, or you will need to move IPLA to a partitioned data set (PDS) and then
reference that PDS.
3. Ensure that the CUU information matches the CUU information that was used to
create the loader general file initially.
4. Submit the JCL.
