Update either the Volume serial field or the Generic unit name field to define the volumes for the data set being allocated.
Type the Volume serial to specify the volume where the data set will reside. If multiple volumes are required, set the Specify multivolume? field to Y.
Allocate a data set to any volume within a unit type by typing the Unit Name. See the DASD Unit Configuration function (CA File Master Plus Option 3.9.3) for a list of the Unit Names available on your system and summary information about each volume within each unit type. If multiple volumes are required, set the Specify multivolume? field to Y.
To alter the sequential file or PDS to use the specified management class, update the one- to eight-position name of the SMS Management Class. You can use the SMS Management Class to control data set characteristics related to the backup, migration, and retention of the data set.
To alter the sequential file or PDS to use the specified storage class, update the one- to eight-position name of the SMS Storage Class. You can use the storage class to control the storage hardware used for the data set.
Type the one- to eight-position name of the SMS Data Class to be used when allocating the sequential file or PDS. You can use the SMS Data Class to control the attributes of the data set being allocated.
Specify the Space allocation unit for the sequential file or PDS being allocated. The primary and secondary allocations are in the specified units.
If you type the first position of one of the valid values, the rest of the Space allocation unit appears in the field. Space can be allocated as one of the following:
Type the Primary allocation amount for the sequential file or PDS. The amount of space allocated in the primary allocation is the specified number of tracks, cylinders, or blocks depending on the allocation unit.
Type the secondary allocation amount for the sequential file or PDS. The amount of space allocated in each secondary allocation is the specified number of tracks, cylinders, or blocks depending on the allocation unit.
Type the desired number of directory blocks when defining a partitioned data set. If defining a sequential file, this field should contain no value or a value of zero.
Type the record format for the sequential file or PDS being defined. Record format is a concatenation of up to 3 one-byte codes that have the following meaning:
For example, 'FB' would be fixed blocked, 'U' would be undefined length, and 'VBA' would be variable blocked with ASCII print control characters.
Type the Logical Record Length for the records to be written to the sequential file or PDS being allocated.
Type the Block size for the sequential file or PDS being allocated.
For variable blocked or fixed blocked files, the Block size field can be empty or contain zero to let the system to calculate the optimum Block size.
If the sequential file or PDS can be deleted after a certain date, type an Expiration Date in CCYYMMDD format.
You can use this optional field to specify whether the data set being allocated is a sequential file, a PDS, a PDS/E, or a large format data set. If this field is blank, the data set is allocated as a PDS if directory blocks are specified; otherwise, the data set is allocated as a sequential file. This field is required only when allocating a PDS/E. Valid values are:
SEQ – Sequential file
PDS – PDS
PDSE – PDS/E
LARGE – large format data set
If the sequential file will be allocated with multiple volumes, set the Specify multivolume? field to Y.
At the top of the screen, you have the option of defining the volumes to be used by Volume serial or by Generic unit name. If a Volume serial is specified, a screen appears and lets you define the rest of the Volume serials for this data set. If a Generic unit name is specified, a screen appears that lets you define the number of volumes of that unit type to be allocated.
