Question:
During IPL System Started tasks wait within ACF9CVER, ACF2 Subsystem does not start, and the system hangs. What can cause this?
Answer:
If the unit esoteric which is specified in the SYSUT1 DD backup work file in the
ACF2 PROC is not defined or not available, ACF2 will not start because of a JCL error which in
turn will cause a system hang.
Other symptoms include message 'IEE132i - device allocation error.' during IPL.
