Steps to take
Follow these steps:
- Update and run the IPLTEXT job to write a new copy of the IPL text. If you install z/OS with a ServerPac, an installation dialog job is provided to perform this action. If you install z/OS with a CBPDO, instructions to perform this action are provided in z/OS Program Directory at the z/OS installation related information website.
Tip: With ICKDSF R17 APAR PM42057, a new parameter
called REMOVEIPLTXT has been added to the REFORMAT command that allows
you to remove IPL text from the volume.
Note: When the IPLTXTEXIST
parameter (which was introduced by ICKDSF R17 APAR PK16403) is specified
with the REFORMAT command using the IPLDD parameter, WTOR message
ICK21836D is suppressed if IPL text already exists.

For a sample IPLTEXT job, see z/OS Program Directory at the z/OS installation related information website. ServerPac provides a similar job for accomplishing this task; see ServerPac: Installing Your Order.
