  1. Dear Colleagues, I’m in big trouble for the unexpected SQL1042C in my shop DB2 LUW V11.1 running on CentOS 6.
    My analysis is shortly described by these sentences:
    [db2inst1@db2 ~]$ db2 “create stogroup SG_4 on ‘/data/new_path1’,’/data5/new_path2′”
    DB20000I The SQL command completed successfully.
    db2inst1@db2 ~]$ db2pd -d DBPRE -storagegroups

    0x00007FA5A561A000 2 2049 NotInUse /data5/new_path2
    Some days working without any negative behavior, therefore we decided to replicate in production (without backup, else too simple) and withot following “” (else too easy).
    Therefore we assume that the reason of SQL1042C be clear (but not 100% sure). Any way, the problem is to recover data, of course. Could you please try to help us before being hanged ?
    Thanks and regards, carlo
