Hi!

I have taken a backup of a set of DASDs using the following JCL
Code:
//DUMP  EXEC PGM=ADRDSSU                                         
//SYSPRINT DD SYSOUT=*                                           
//TAPE  DD UNIT=T3590,VOL=SER=TAPE01,                             
//         DSN=CBCACHE.CICS.NCP.BKUP(+1),DISP=(,CATLG,DELETE),   
//         DSNTYPE=LARGE,                                         
//         DCB=BLKSIZE=32760                                     
//DASD1 DD UNIT=3390,VOL=SER=CBC017,DISP=SHR                     
//DASD2 DD UNIT=3390,VOL=SER=CBC018,DISP=SHR                     
//DASD3 DD UNIT=3390,VOL=SER=CBC019,DISP=SHR                     
//DASD4 DD UNIT=3390,VOL=SER=CBC020,DISP=SHR                     
//DASD5 DD UNIT=3390,VOL=SER=CBC021,DISP=SHR                     
//DASD6 DD UNIT=3390,VOL=SER=CBC056,DISP=SHR                     
//DASD7 DD UNIT=3390,VOL=SER=CBC057,DISP=SHR                     
//DASD8 DD UNIT=3390,VOL=SER=CBC058,DISP=SHR                     
//SYSIN DD *                                                     
  DUMP DATASET -                                                 
   (INC(CBCACHE.**) -                                             
   BY(DSORG EQ (PDS,PDSE,SAM,VSAM))) -                           
   ALLD(*) -                                                     
   ALLE PROCESS(SYS1) -                                           
   INDDNAME(DASD1,DASD2,DASD3,DASD4,DASD5,DASD6,DASD7,DASD8) -   
   OUTDDNAME(TAPE)                                               
/*   




I am only able to restore the datasets using RESTORE DATASET command in ADRDSSU out of the above DUMP. But i want the flexiblity of restoring the all the datasets residing on certain volume if a volume fails, because in that case i would not know the what datasets were residing on the failed volume.

That's the difference between logical and physical dumps for you.

Must admit that I prefer logical dumps, because if one volume goes tits up it is likely that it contained multi volume datasets, and if you restore just one volumes data in a multivol dataset you're just asking for trouble.

Also, talk to your storage people to see if there is a HSM dump and incremental backups available.

What a wonderfull expression expat.
But how are you using that with a female in the storage group?
Something like : "a volume went tits up", you got any experience with that?

The young lady that shared an office with me in Germany thought that it was a hilarious statement. Along with a few others.

And she also learnt quite a few of the old cockney rhyming slang terms too, such as threepenny bits icon_biggrin.gif
