During the installation of RO99124, the VMFBLD PPF ZVMT020A VMTAPE ( STATUS command displayed the message VMFUTL2070W Build list NUCBL48 is not in the :BLD section of product parameter file ZVMT020A PPF - RC = 4.
What is my exposure?
Unfortunately, this is "expected" and there is really not anything that can be done to prevent the message from appearing each time you run VMFBLD.
This is the result of the NUCBL48 BuildList being replaced by the NUCBL51 BuildList for VM:Tape. VMSES knows that NUCBL48 was required in the past. VMSES sees this and issues the VMFUTL2070W message even though it is now marked as DELETED in the control files.
At the end of the verbiage for VMFUTL2070W it states something to the effect "If the BuildList was removed intentionally, this message can be ignored."
The NUCBL48 BuildList was removed intentionally, so you can ignore the message.
