IOV104
Explanation: (soft abend) A device simulation routine
presented initial status containing device end with
neither channel end nor busy. HCPIOVUS detects this
error.
User Response: The SAVBK chain anchored in
IORSAVE indicates the environment at the time of the
failure. The CPCBK (in this SAVBK) indicates the status
of simulation for the current CCW. CPCRTNAD
addresses the simulation routine being used. If the logic
of the simulation routine causes it to present status
incorrectly, correct it so that when it presents device end
in initial status, either channel end or busy also
appears.
Note: HCPIOVUS may have been entered using a
CALL to HCPIOVUC.
IOV105
Explanation: (soft abend) A device simulation routine
presented status that lacks device end after previously
presenting channel end for the current CCW.
HCPIOVUS detects this error.
User Response: The SAVBK chain anchored in
IORSAVE indicates the environment at the time of the
failure. The CPCBK (in this SAVBK) indicates the status
of simulation for the current CCW. CPCRTNAD
addresses the simulation routine being used. If the logic
of the simulation routine causes it to present status
incorrectly, correct it so that once it presents channel
end for a command, the next status presented contains
device end. Otherwise, try to determine how
CPCDTFLG.CPCDTCER (byte.bit) was set on
incorrectly.
Note: HCPIOVUS may have been entered using a
CALL to HCPIOVUC.
IOV106
Explanation: (soft abend) A device simulation routine
requested data service after presenting nonzero status
for the current CCW. HCPIOVMV detects this error.
User Response: The SAVBK chain anchored in
IORSAVE indicates the environment at the time of the
failure. The CPCBK (in this SAVBK) indicates the status
of simulation for the current CCW. CPCRTNAD
addresses the simulation routine being used. If the logic
for the simulation routine causes it to request data
incorrectly, correct it so that it does not request data
from the channel simulator after presenting nonzero
status for a CCW. Otherwise, try to determine how
CPCDTFLG.CPCDTCER or CPCDTFLG.CPCDTEND
was set on incorrectly.
IOV107
Explanation: (soft abend) A device simulation routine
requested additional data service for the current CCW
after being signalled to stop data transfer. HCPIOVMV
detects this error.
User Response: The SAVBK chain anchored in
IORSAVE indicates the environment at the time of the
failure. The CPCBK (in this SAVBK) indicates the status
of simulation for the current CCW. CPCRTNAD
addresses the simulation routine being used. If the logic
for the simulation routine causes it to request data
incorrectly, correct it so that it does not request data
from the channel simulator after receiving a stop signal.
Otherwise, try to determine how
CPCDTFLG.CPCDTSTP (byte.bit) was set on
incorrectly.
IOV108
Explanation: (soft abend) A device simulation routine
invoked HCPIOVUC, specifying sense data length zero.
User Response: The SAVBK chain anchored in
IORSAVE indicates the environment at the time of the
failure. The CPCBK (in this SAVBK) indicates the status
of simulation for the current CCW. CPCRTNAD
addresses the simulation routine being used. If the logic
for the simulation routine causes it to present sense
data incorrectly, correct it to invoke HCPIOVUC with a
nonzero length for the sense data. Otherwise, try to
determine how HCPIOVUC lost the correct data count.
IOV109
Explanation: (soft abend) A device simulation routine
invoked HCPIOVUC, specifying sense data that
overlaps the sense data in the IORBK.
User Response: The SAVBK chain anchored in
IORSAVE indicates the environment at the time of the
failure. The CPCBK (in this SAVBK) indicates the status
of simulation for the current CCW. CPCRTNAD
addresses the simulation routine being used. If the logic
for the simulation routine causes it to present sense
data incorrectly, correct it to invoke HCPIOVUC with a
source address for the sense data so that none of the
sense bytes are within the active IORBK’s sense field.
Otherwise, try to determine how HCPIOVUC lost the
correct sense data address and/or count.
IOV110
IOV104 IOV110
Explanation: (soft abend) A device simulation routine
invoked HCPIOVUC, specifying more sense data than
an IORBK can contain.
User Response: The SAVBK chain anchored in
IORSAVE indicates the environment at the time of the
failure. The CPCBK (in this SAVBK) indicates the status
of simulation for the current CCW. CPCRTNAD
addresses the simulation routine being used. If the logic
