If the Global VCAT is still available, use IDCAMS Repro to copy the Global VCAT into a newly defined BSDS.
If both the BSDS and the Global VCAT are lost but the DASD buffer is intact, restore the BSDS from the latest backup and recover the Global VCAT as explained in the topic Recovering the Global VCAT.
All CA Vtape Subsystems participating in the CA Vtape Complex sharing the BSDS to be restored must be shut down in order to perform the restore.
The following is a sample of a CA Disk restore job:
//JOBNAME JOB … //RESTORE EXEC RESTORE //SYSIN DD * RESTORE DSN=HLQ.BSDS1 //
The following is a sample of a DFSMSdss restore job:
//JOBNAME JOB … //RESTORE EXEC PGM=ADRDSSU,REGION=4M //SYSPRINT DD SYSOUT=* //INPUT DD DISP=SHR,DSN=HLQ.BSDS.BACKUP(+0) //OUTPUT DD DISP=SHR,UNIT=3390,VOL=SER=XXXXXX //SYSIN DD * RESTORE DATASET(INCLUDE(HLQ.BSDS1)) - PHYSINDDNAME(INPUT) - OUTDDNAME(OUTPUT) - REPLACE //
