When running close to the real storage installation, you may experience
messages indicating storage shortages on SDM LPARs. Because SDM address
spaces use a large amount of fixed storage, the SDM address spaces
will always report first in the IRA404I messages as users of large
amounts of storage.
Symptoms
Error messages reported:
- IRA400E 04,PAGEABLE STORAGE SHORTAGE
- IRA404I ANTAS00x ASID 00xx OWNS 0000###### PAGES, 0000###### FIXED,
0000###### FIXED IN SHORTAGE AREA
- IRA401E 04,CRITICAL PAGEABLE STORAGE SHORTAGE (sometimes)
How to investigate
If you aren't witnessing
a *IEA602I ADDRESS SPACE CREATE FAILED message, then this can be considered
only a warning until storage is adjusted.
F ANTAS000,DUMP
(generates dump, gathering storage usage from all address spaces)
Note: If no impact to environment, and only warnings are displayed,
follow-up during next business day.
What to send: - DUMPs (Generated by previous command, from all address spaces)
- SYSLOG (Including timestamps leading up to and from reported error)
Recovery actions
Reduce storage demand by
terminating job tasks until shortage is relieved.
