DSNB550I: Page stealing method change

Message DSNB550I is displayed only after a buffer pool is allocated for which the requested FRAMESIZE and PGSTEAL values are FRAMESIZE(2G) and PGSTEAL(NONE). 

DSNB550I - CURRENT PAGE STEALING METHOD = NONE 
           PAGE STEALING METHOD BEING USED = LRU
PGSTEAL(NONE) and FRAMESIZE(2G) are not compatible in Db2 13. If you specify these options together, Db2 issues message DSNB549I and uses the PGSTEAL(LRU) algorithm until the next allocation of the buffer pool. However, PGSTEAL(NONE) is recorded in the BSDS. To use PGSTEAL(NONE), specify FRAMESIZE(1M) or FRAMESIZE(4K).
