Establish or Change a Map
[RU,]IOMAP,sourceLU,destinationLU,destinationNode,securityCode
Parameters
sourceLU | Mappable LU on source system. |
destinationLU | Destination system LU of map. The destinationLU must be |
| associated with a unitrecord device (such as a terminal, printer, |
| or mag tape unit). |
| Options: |
| Set bit 15 to enable the header flag. Remote I/O Mapping will |
| write a message of the following form to the destination LU |
| preceding each record sent to that LU: |
| MESSAGE FROM NODE # nnnnn PRGM ppppp AT DAY dddd, hh :mm :ss |
| Where: nnnnn is the source node (node where the message |
| originated); ppppp is the name of the program sending the |
| message (or SYS I/O if the I/O request is from the system or |
| class buffered); and ddddd hh mm ss is the day and time |
| that the request was made at the source node. |
| Set bit 14 to enable the prompt flag. Remote I/O Mapping will |
| write a prompt of the following form to the destination LU |
| preceding each read request mapped from the source LU: |
| (nnnnn) |
| Where: nnnnn is the source node. |
| Set bit 13 with bit 14 to change the read request timeout to 20 |
| minutes but suppress the prompt flag. |
destinationNode | Destination node number of the map (the node of the |
| destination LU). |
securityCode | Network Management security code. |
Return Parameters
First Parameter | sourceLU if map was successfully established, otherwise one | ||
| of the following negative error codes: | ||
| D | ||
| D | (177776B) if sourceLU is not a mappable LU | |
| D | ||
|
| correctly | |
| D | (177774B) if destinationLU is mappable | |
| D | (177773B) if destinationNode is not known to the | |
|
| local node |
