To see a list of the actions associated with system holds, use the LIST command with both the SYSMODS and HOLDDATA operands, as shown:

SET      BDY(GLOBAL)    /* set to global zone       */.
LIST     SYSMODS HOLDDATA       /* list only the HOLDDATA   */.
         

The following example output from the LIST SYSMODS HOLDDATA shows the actions

LIST SYSMODS HOLDDATA.
