IST872I

Explanation
 This message is the first in a group of messages
that VTAM® issues in response
to one of the following:  VARY DRDS command
MODIFY DR,TYPE=MOVE command
When a CONTACT has failed with a sense code indicating a DR mismatch.
In this case, an internal MODIFY DR,TYPE=MOVE was sent to move the
PU from the generated line to the line that last attached the NCP
to the PU.

 Possible message groups follow:  IST872I  DR MOVE MISMATCH DETECTED FOR puname
IST523I  REASON = RESOURCE WAS MOVED FROM line1, NOT line2
IST314I  END

IST872I  DR MOVE MISMATCH DETECTED FOR puname
IST523I  REASON = puname IS ON line1 IN NCP
IST401I  F DR,TYPE=MOVE INITIATED FOR puname
IST314I  END

 IST401I  puname is the name of the physical unit that
has been moved.

 IST523I  puname is the name of the physical unit that
has been moved.
line1 is the name of the line from which the
NCP actually moved puname.
line2 is the name of the line from which VTAM thought puname was
to be moved.

 IST872I  puname is the name of the physical unit that
has been moved.

System action
 Processing continues with activation if a MODIFY
DR,TYPE=MOVE or VARY DRDS command was issued by the operator.
 If
the group with the IST401I is issued, an internal MODIFY DR,TYPE=MOVE
has been initiated to move the PU to the line that last attached the
NCP to the PU. The PU and LUs will be reactivated. 

Operator response
 If the message group with message IST401I
is issued, save the system log for problem determination. Otherwise,
activate the resource immediately, if possible. 

System programmer response
 Determine whether the PU is on the
correct line in VTAMLST or whether a MODIFY DR,TYPE=MOVE or ADD needs
to be issued to put the PU on the correct line.
