Explanation
Where text is:
REAL STORAGE AMOUNTS:
TOTAL AVAILABLE ONLINE: xxx [M|G|T]
LFAREA LIMIT FOR xM, xG, OR x
T: xxx [M|G|T] | [0 (not supported)]
LFAREA LIMIT FOR SUM OF 1M= AND 2G=: xxx[ M | G | T ] | [0 (not supported)]
LFAREA LIMIT FOR 2GB PAGES FOR 2G= : [xxxxxxx] | [0 (not supported) ]
This
is an informational message that describes certain views of storage
that pertain to the sysparm LFAREA specification:
- TOTAL AVAILABLE ONLINE
- The amount of available online storage located at IPL, which is used to calculate each of the following limits.
- LFAREA LIMIT FOR xM, xG, OR xT
- The system limit used when xM, xG, or xT syntax is used for the LFAREA specification. This limit calculation is: [(80% of the total available online storage at IPL) minus 2G]. If the EDAT facility is not installed, 0 (not supported) is displayed.
- LIMIT FOR SUM OF 1M= AND 2G=
- The system limit used when 1M= and 2G= syntax is used for the LFAREA specification. This limit calculation is: [80% of (the total available online storage at IPL minus 4G)]. If the EDAT facility is not installed, 0 (not supported) is displayed.
- LFAREA LIMIT FOR 2GB PAGES FOR 2G=
- The limit of the number of 2 GB pages that were found that could be specified for the 2G= subparameter on the LFAREA specification, provided the sum of 1M= and 2G= remains at or below the LIMIT FOR SUM OF 1M= AND 2G=. If the EDAT facility 2 is not installed, 0 (not supported) is displayed. Each 2 GB page must reside in 2 GB of contiguous storage starting on a 2 GB boundary. If online storage is fragmented with offline increments such that there are gaps that prevent 2 GB areas of contiguous storage on a 2 GB boundary from being found, there can be fewer 2 GB pages than the system limit would suggest.
Note: This message is issued regardless of whether
the LFAREA parameter was specified.
System action
The IPL continues.
Operator response
None.
System programmer response
This message helps you determine the amounts of storage available for the large frame area, particularly if the amounts requested with the LFAREA parameter are not reflected in the IAR048I message. If the number of 2 GB pages are fewer than expected, determine whether the storage is fragmented by offline storage increments.
