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 -1 (177777B) if securityCode was incorrect

 

D

-2

(177776B) if sourceLU is not a mappable LU

 

D -3 (177775B) if Remote I/O Mapping is not set up

 

 

correctly

 

D

-4

(177774B) if destinationLU is mappable

 

D

-5

(177773B) if destinationNode is not known to the

 

 

local node
