Issue/Introduction

While converting DFSMSHsm data to Disk™ Backup and Restore, the HSMGEN2 tries to recover with newname and then backup the data sets again with their original date and time. The original Volume Vol1 does not exist anymore. So the existing backup is recovered with a newname to the Volume Vol3. 

The following messages are issued:
ADSDM367*0349 OBTAIN FAILED FOR FM4 DSCB - JFCBVOLS Vol1 OBTAIN RC 0000 
ADSDM120 2464 ERROR ALLOCATING VOLUME REQUIRED FOR PROCESSING. VOLUME = Vol1 , DSNAME =...

Environment

Release: Disk™ Backup and Restore

Resolution

The HSMGEN2 job recovers the data set to a volume specified on the convert command, but the backup is created with the original volume which does not exist anymore. The data set exist on the Vol3 Volume, but is not cataloged. 

1- Select data sets with error 2464 from this HSMGEN2 run
2- Try to recover them directly from DFSMSHsm
3- This should not work as well. Below you can see the error message, then the generated ARC statement to find the real name of the data set. 
4- Do a HLIST and a HRECOVER, you should see the following message: 
ARC0138I NO MCDS INFORMATION FOUND FOR DATASET SYS1.XXXX 
5- Use DFSMSHsm tool to check BCDS/MCDS integrity. 

It is better to list the contents and compare with the catalog entries before running the Disk conversion to ensure DFSMS HSM CDS are correct.
