When running TSSXTEND to copy the security file, a U0008 abend is received.
COMPLETION CODE - SYSTEM=000 USER=0008 REASON=00000000
You can not run TSSXTEND to copy into a Top Secret security file that has already been populated. You must allocate a new CA Top Secret security file and run TSSXTEND to copy into the newly allocated file.
If you run TSSXTEND and the job fails, most likely you will need to delete and recreate the files.
