CHECK(IBMIOS,IOS_STORAGE_IOSBLKS) determined that 31-bit IOS blocks are currently in the expected state. When enabled, 31-bit IOS blocks can reduce storage constraints below 16 megabytes. However, there may be legacy software that scans the IOS blocks and require them to be below 16 megabytes.
STORAGE IOSBLKS=31 has been specified if enabled, or STORAGE IOSBLKS=24 has been specified if disabled.
The expected state of 31-bit IOS Blocks can be changed by supplying a check parameter of IOSBLKS(31) or IOSBLKS(24).
The system continues processing.
