Return LU Mapping Information

[RU,]IOMAP,sourceLU,–1

Parameters

sourceLU

The mappable LU for which you want IOMAP to display

 

information. If you specify a nonmappable LU, IOMAP will

 

display map information for the first mappable LU greater than

 

sourceLU.

Return Parameters

First Parameter

The sourceLU. If sourceLU is not mappable, this will be the

 

first mappable LU greater than sourceLU. Otherwise, it is

 

one of the following negative error codes:

 

D -2 (177776B) if the sourceLU is not a •mappable" LU

 

and there are no mappable LUs greater than sourceLU

 

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

 

correctly

Second Parameter

destination LU of map for the LU returned in the first

 

parameter.

Third Parameter

destination node number of map for the LU returned in the

 

first parameter.

Fourth Parameter

The type of remote operating system ($OPSYS value, as

 

documented in the RTEA manual set).
