 20  14  Unsigned     4  STOBPG_PGDBR(1:20)  Number of times a block of the
                                             corresponding size was read. Each
                                             index number from 1 to 19
                                             corresponds to the block size
                                             number. Example: PGDBR(8) = the
                                             number of times a block of 8 pages
                                             was read. For index number 20,
                                             this is the number of times a
                                             block of 20 or more pages was
                                             read.
100  64  Character   80  STOBPG_PGDBM_TBL    
100  64  Unsigned     4  STOBPG_PGDBM(1:20)  Number of times a block of the
                                             corresponding size was migrated.
                                             Each index number from 1 to 19
                                             corresponds to the block size by a
                                             factor of 2. Example: PGDBM(1) =
                                             the number of times a block of 1
                                             or 2 pages was migrated. PGDBM(6)
                                             = the number of times a block of
                                             11 or 12 pages was migrated. For
                                             index number 20, this is the
                                             number of times a block of 39 or
                                             more pages was migrated.
180  B4  Character   80  STOBPG_PGDBS_TBL    
180  B4  Unsigned     4  STOBPG_PGDBS(1:20)  Number of times a block of the
                                             corresponding size was written.
                                             Each index number from 1 to 19
                                             corresponds to the block size by a
                                             factor of 2. Example: PGDBS(1) =
                                             the number of times a a block of 1
                                             or 2 pages was written. PGDBS(6) =
                                             the number of times a block of 11
                                             or 12 pages was written. For index
                                             number 20, this is the number of
                                             times a block of 39 or more pages
                                             was written.
