Of course, having a team of IBMers on your system on a daily
basis trying to diagnose a simple flipping save and having to do
2 IPLs within a week is a real hoot. Luckily it's just the
programmer's LPar.
Oh, if your save abends during a save while active you can forget
saving that library active until after the next IPL. "changes"
are recorded off to the side and it gets really confused when the
save abends like that. Claims the objects being processed during
the save 'may' be damaged but they're really not. The IPL clears
them up.
Presumably "abends" means an "abnormal end" from the perspective
of the OS [code] itself rather than a "/normal/ end due to error"
from the perspective of the user? Such that the "abend" is a
defect, which if the defect did not exist, then the message that was
issued to warn about the status of the objects possibly being
damaged plus that an IPL is required to clear the problem, may be at
least somewhat acceptable.? If however the save request ends with
/normal/ error conditions\scenarios such as "object could not be
allocated" or "media not ready" such that if the message was issued
to warn about the status of the objects possibly being damaged, that
would hopefully be diagnosed by IBM as a defect.?
Additionally, if the message about "object may be damaged" due to
an internal OS sfw error having led to the SWA failure was issued,
then the message is probably accurate, such that the IPL activity
does not necessarily always just clear them up; i.e. YMMV.? The
system storage management will have started tracking changed pages
to the objects [IIRC, by redirecting the save activity to a backup
copy of the pre-changed segment], so if the abnormal end itself or
something between then and the IPL might also mess up that tracking
[maybe only loss of main memory\storage], then the object or its
data may not survive well.? I would have to think too hard to
remember how things worked to understand the if\how a scenario might
end with damaged object(s).
