IAR043I LFAREA=(specification) WAS SPECIFIED WHICH TOTALS [xxxxxxxM | xxxxG | xT] AND EXCEEDS THE SYSTEM LIMIT OF [yyyyyyyM | yyyyG | yT].
Explanation
The LFAREA parameter specified for real storage to be reserved in the large frame area for 1 MB or 2 GB pages, but the request exceeds the system limit. If xM, xG, xT, or x% syntax is specified, the percentage request is calculated by first multiplying the percentage by the online real storage, and then subtracting 2G: (percentage * online real storage) – 2G. If 1M= or 2G= syntax is specified, the percentage request is calculated by first subtracting 4G from the online real storage, and then multiplying that by the percentage: (online real storage – 4G) * percentage. For 1M= and 2G= syntax, when both a target and a minimum amount are provided, the minimum amount is applied toward the limit and is used in the total amount indicated.
System action
- If xM, xG, xT, or x% syntax was specified, the system prompts for reentry of the LFAREA parameter.
- If 1M= or 2G= syntax was specified:
- If PROMPT was specified, either explicitly or by default, the system prompts for reentry of the LFAREA parameter.
- If NOPROMPT was specified, the LFAREA specification is ignored and zero 1 MB and zero 2 GB pages are reserved in the large frame area and IPL continues.
Operator response
Ensure that the correct IEASYSxx member is used for this IPL. If the correct IEASYSxx member is used, but sufficient storage is not available, contact your system programmer.
System programmer response
If 1 MB or 2 GB pages are required, ensure that enough storage is installed for the z/OS® image such that the requested amount of storage is not over the limit. Refer to the output of message IAR040I for the system limits.
