Once the DSMSERV RESTORE DB command selects a candidate database backup series, it will validate the information from the backup data stream and compare it to the information available from the volume history file. In this case, the database backup is missing information which is needed in order to perform a restore of the server database.
None.
This is likely caused by not having all the necessary volumes available and specified in the volume history file. Or this is caused by having the wrong volume designated with sequence 10001. If a volume in the volume history file for this backup series and operation is assigned 10001, try assigning a different volume as sequence 10001. The volume assigned sequence 10001 is expected to have the self-describing validation information and signatures that are used by the restore processing for validation of a given operation for a backup series. If this information is not found or correct, this would result in a restore failure.
