Example 1. DUMP FULL

You can use DFSMSdss to dump the entire contents of a volume to tape or DASD, and have DFSMSdss restore the dump at a later time. Here, you can use the DFSMSdss DUMP FULL command. After you create a dump of the boot volume, you can restore the volume to multiple volumes as a way of making identical copies of the basic Linux system.

On the DUMP FULL command, include the keyword ALLEXCP to cause DFSMSdss to process all of the data set or partition, even if unused. ALLEXCP is required; your data is not backed up if you do not specify it.

Figure 1 shows an example of the JCL (the Linux volume has volser LNX200).

//LXD2D1BB JOB ,'IBMUSER',MSGLEVEL=(1,1),TIME=(5,0),REGION=4096K,
//      MSGCLASS=H,CLASS=A 
//STEPT02  EXEC PGM=ADRDSSU
//SYSPRINT DD SYSOUT=*
//SOURCE   DD UNIT=3390,VOL=SER=LNX200,DISP=OLD
//TARGET   DD UNIT=TAPE,VOL=(PRIVAT,SER=111111),DISP=(NEW,CATLG),
//            DSN=TDS.DUMP200,LABEL=(1,SL)
//SYSIN    DD *  
 DUMP FULL INDDNAME(SOURCE) OUTDDNAME(TARGET) -
       ALLEXCP

You can also dump to two or more output tapes at the same time, for example, if you wanted a backup and a copy of the backup for storage off-site.

Figure 2 shows an example of the JCL.
