    How can I return a group of volumes that are in soft fenced state to a normal state?
    Thanks

    Hi, If you can't use your replication management software (CSM / GDPS) to reset the soft fence state on these volumes, you can use the DSCLI  command "manageckdvol -action sfdisable xxxx-yyyy" where xxxx-yyyy is the volume range you want to unfence.

    Hi

    For z/OS attached volumes, you can also use ICKDSF jobs to unfence devices. You typically also need to specify the 2107 storage control unit Serial

    or

    https://www.ibm.com/docs/en/zos/2.5.0?topic=op-clearfence-parameter-clear-fence-status

    Example:

    //*---------------------------------------------               
    //* !!!!! ICKDSF UNFENCE CMD !!!!!                             
    //*---------------------------------------------               
    //STEP0001 EXEC  PGM=ICKDSF,REGION=3000K,PARM='NOREPLYU'       
    //SYSPRINT DD  SYSOUT=(*,,1TAB)                                
    //SYSIN    DD  *                                               
     CONTROL UNIT(7BB0) SPID CLEARFENCE SERIAL(12345) SCOPE(DEV)   
     CONTROL UNIT(7BB0) SOFT CLEARFENCE SERIAL(12345) SCOPE(DEV)

    Thanks for the feedback, In fact I can't do IPL to access Z/OS
