Introduction:

When starting a system with a new level of z/OS, with the CA Disk OPEN SVC Zaps installed,
if during IPL several tasks abend and the Master Scheduler abends FF4-N/A and the IPL stops,
the FF4 abend is caused because the system can not find module ADSMVS60 during IPL.

Here is what to look for.

Console messages that can be seen are:

Instructions:

Make sure that:

1. The CA Disk OPEN SVC member ADSMVS60 is in the LPA library concatenation.

2. The SVC table has been updated by adding the following line to the IEASVCxx member of your SYS1.PARMLIB:
SVCPARM 244,REPLACE,TYPE(4),APF(NO),EPNAME(ADSMVS60)

3. The number assigned to the OPEN SVC is the same as the value specified in each of the four SVC Zaps installed.
The default value in the zaps is x'F4' (d'244') and the instruction in the zaps is '0AF4'.

Most of the time the problem is the SVC number assigned.
The IEASVCxx entry is setup to use a different SVC number than SVC 244 (x'F4').
Changing the open zaps to the correct SVC number will solve the problem and permit the system to IPL successfully.
