Monitoring for BRM1429 not working

I have an automated process that uses a BRMS volume.
If the volume is still being used on a different LPAR, I get BRM1429.
Volume sets not available on devices TAPMLB01.(C G)

I tried monitoring for the BRM1429, adding a delay, but the MONMSG was ignored.
What am I missing with the BRM1429.

RETRY: RSTLIBBRM SAVLIB(TEST) DEV(TAPMLB01) +

MONMSG MSGID(CPF412F CPF3794 CPF4528 CPF0000 +
BRM1429) EXEC(GOTO CMDLBL(DELAY)) /* +
delay job for 5 minutes */

DELAY: DLYJOB DLY(300)
GOTO CMDLBL(RETRY)

Thank You
