A WRITE_LCONTROLS request that specifies KEYRANGESTATE=DEFINE might complete prematurely if the coupling facility model dependent timeout criteria is exceeded. The caller is expected to reissue the request until it completes without timing out.

If this happens, the appropriate return and reason codes are retuned in the answer area. Continue reissuing the WRITE_LCONTROLS request until the return code indicates that all processing has completed.
