I thought that z/VSE 5.1 was suppose to have the ability to have 4 byte address range for devices listed in the IPL deck, but I can not find any reference in the Release Notes.

Larry,

 

Look in System Control Statements, under the Add command.

cuu|pcuu

Indicates the physical device address (defined during I/O configuration) of the device to be added. Both pcuu and cuu define physical device addresses and are distinguished as follows:

cuu

Can be in the range between X'000' and X'FFF'. If the physical device address is in this range, the VSE address equals the physical address.

pcuu

Can be in the range between X'0000' and X'FFFF'. If the physical device address is larger than X'FFF', a VSE address in the range between X'000' and X'FFF' must be assigned via "as." For example:

 

                ADD 1131 as 131,3380

 

The format cuu:cuu|pcuu:pcuu or cuu..cuu|pcuu..pcuu indicates that a series of devices of the same type, starting with the first cuu|pcuu and ending with the second cuu|pcuu is to be added. For example,

 

            ADD 130:137,3380

 

defines eight 3380 devices with addresses 130 through 137.

If you add a series of physical device addresses larger than X'FFF' and assign VSE addresses to them, the range has to be equal. For example,

 

            ADD 2120..2125 as 120..125,3480

 

defines six 3480 devices with addresses 2120 through 2125 and maps them to six VSE addresses 120 through 125.

Refer to "Extended Physical Address Support" in z/VSE Planning for more information.
