IPL specifies the type of device from which Stand-Alone Services is to be IPLed. The system then creates the appropriate loader for the specified device type. If you do not specify the IPL parameter, the system creates a core image suitable for IPLing from a card reader (or a tape drive).

CARD specifies that the core image is to be used for IPLing from a card reader. As a result, the core image is created with BLKSIZE=80 and LRECL=80, and is placed in the data set specified by the OUTDD parameter. You can use this core image to IPL from a card reader (or a tape drive). If you specify CARD, you must also specify the OUTDDNAME parameter. Create the output data set with DSORG=PS, RECFM=F, BLKSIZE=80 and LRECL=80.

TAPE specifies that the core image is to be used for IPLing from a tape drive. As a result, the tape is created with a blocksize optimized for tape. IBM® recommends that you specify TAPE when IPLing from a tape drive. If you specify TAPE, you must also specify the OUTDDNAME parameter. Create the output data set with DSORG=PS, RECFM=U, BLKSIZE=32760, and LRECL=32760.

Note that you cannot use an encrypted tape as the source for an IPL. If you attempt to do so, DFSMSdss fails the BUILDSA command.

DASD specifies that the core image is to be used for IPLing from a DASD volume. As a result, the core image is created with a record size optimized for DASD. If you specify DASD, you must also specify the OUTDYNAM parameter. The core image is placed in data set SYS1.ADR.SAIPLD.Vvolser, which is allocated by Stand-Alone Services in the volume specified on the OUTDYNAM parameter (that is, the volume from which the Stand-Alone Services program is to be IPLed). This core image can only be used to IPL from the DASD volume specified in the OUTDYNAM parameter.

Additionally, the BUILDSA command invokes the ICKDSF REFORMAT command to place the IPLTEXT and bootstrap records on this volume. The BUILDSA command provides ICKDSF with IPLTEXT necessary to IPL the Stand-Alone Services core image.
