An exemplary embodiment of the invention relates to a method, system, and
storage medium for resolving contention issues by a channel in a fiber
optic switch environment that occur during channel program execution. The
method comprises a channel receiving a status packet indicating a device
is no longer busy. The method also includes specifying whether the
channel intends to re-initiate a channel program that previously resulted
in the device busy status. If the channel does not intend to re-initiate
the channel program, a first combination of bits in a re-initiate field
of a status-acceptance packet are set which indicate that the channel
will take no further action. If the channel intends to re-initiate the
channel program, a second combination of bits in the re-initiate field of
the status-acceptance packet are set, indicating that the channel will
re-initiate the channel program. The method further includes transmitting
the status-acceptance packet to a control unit. The invention also
includes a system and a storage medium.
