DSNU1636I RESTORE SYSTEM UTILITY FAILED BECAUSE THE SPECIFIED DUMPCLASS IS NOT KNOWN TO DFSMSHSM

Explanation
 The RESTORE SYSTEM Utility failed to restore the Db2 database copy pool because the DFSMShsm dump
pclass specified does not exist for the system-level backup. Specify
the DFSMShsm dump
class via the RESTORE SYSTEM DUMPCLASS option or via installation
panel DSNTIP6 by specifying RESTORE/RECOVER From dump => YES and
DUMP CLASS NAME => hsm-dumpclass-nm.

System action
 The RESTORE SYSTEM Utility terminates processing.

System programmer response
 Issue the DFSMShsm LIST COPYPOOL command
with the ALLVOLS option for the Db2 database
copy pool. Run the Print Log Map Utility (DSNJU004) to print the system-level
backup information. If data sharing, ensure that the system-level
backup information from all members is gathered. Locate the systemlevel
backup information in the DSNJU004 output and compare it with the
output from the LIST COPYPOOL command. The LIST COPYPOOL command output
shows the DFSMShsm dump
classes associated with each system-level backup.

Severity
