IBM System Storage DS6000 Series: Copy Services with IBM System z

Example 26-16 Simulate primary site failure through CGROUP FREEZE

//* ---------------------------- TSO ------------ FAILO (2) ----- ***
//* SIMULATE PRIMARY FAILURE WITH CGROUP FREEZE/RUN        ***
//* HARDER PRIMARY FAILURE THROUGH VARY OFFLINE,FORCE     ***
//* -------------------------------------------------------------- ***
//FREEZE EXEC PGM=IKJEFT01
//SYSPRINT DD SYSOUT=*
//SYSTSPRT DD SYSOUT=*
//SYSTSIN DD DDNAME=SYSIN

CGROUP DEVN (X'2C00')        +
    PRIM (X'2C00' 27131 X'0C')    +
    SEC (X'3C00' 73081 X'0C')    +
    FREEZE

CGROUP DEVN (X'2D00')        +
    PRIM (X'2D00' 27131 X'0D')    +
    SEC (X'3D00' 73081 X'0D')    +
    FREEZE

//* -------------------------------------------------------------- ***
//RUN EXEC PGM=IKJEFT01
//SYSPRINT DD SYSOUT=*
//SYSTSPRT DD SYSOUT=*
//SYSTSIN DD DDNAME=SYSIN

CGROUP DEVN (X'2C00')        +
    PRIM (X'2C00' 27131 X'0C')    +
    SEC (X'3C00' 73081 X'0C')    +
    RUN

CGROUP DEVN (X'2D00')        +
    PRIM (X'2D00' 27131 X'0D')    +
    SEC (X'3D00' 73081 X'0D')    +
    RUN

CGROUP FREEZE immediately removes the paths between the primary and secondary
LSSs. An immediate CGROUP RUN command would end a potential extended long busy
(ELB) timer. Note that ELB is not possible and not useful for Global Copy.

26.4.2 Stop a Global Mirror session

When the local storage disk subsystem is still operational, you may explicitly stop the Global
Mirror session; see Example 26-17.

Example 26-17 Stop Global Mirror session when local site is still accessible
