-BLKSIZE n|nK|nM|nG|MIN|MAX|hexX

BLKSIZE=n|nK|nM|nG|MIN|MAX|hexX

n|nK|nM|nG: specifies the block size in multiples of 1; 1,024 (kilobytes); 1,048,576 (megabytes); and 1,073,741,824 (gigabytes), respectively. For example, a value of 8 specifies 8 bytes and a value of 3M specifies 3,145,728 bytes.
MIN: specifies 0 bytes.
MAX: specifies 2,147,483,647 bytes. On 64-bit systems, MAX is 9,007,199,254,740,992.
hexX: specifies the number of bytes in hexadecimal notation. For example, 2DX specifies 45 bytes.

Details

The BLKSIZE= option sets the physical block size of the library. After the library has been created, the block size cannot be changed.

The BLKSIZE= data set option takes precedence over the BLKSIZE= system option.
