Anybody have any idea why IBM decided to remove ASM's technique of
suspending channel programs in APAR OA14248? The APAR is titled "NEW
FUNCTION". Is suspending channel programs now considered a false savings?
According to my sources, OA14248 is, in part, to solve the problem
described in OA09675. This APAR was a problem when an ASM suspended I/O
was on a PAV alias, and the alias is removed from the base, the
suspended I/O might be left in limbo. Because of OA14248 no PTF is
planned for OA09675.
I suspect that they discovered that on modern systems, the time savings
from the suspended I/O was not sufficient to justify it and the
associated issues like OA09675.
