  • This problem is fixed in 5.2.3.1

Fix solutions refer to page:

_apars.html

Benefits of the solution:
If the error condition is encountered, the file being recalled
will experience a soft I/O error, rather than having the FSD
crash.  The reduced severity will hopefully allow detailed
tracesto be enabled for a quick recreation of the condition so a
root cause can be found to the initial problem.

Work Around:
None.

Problem trigger:
The initial problem was unable to be recreated in the lab.

Symptom:
Customer who experienced the LogAssert (noted in the APAR title)
will now receive a soft I/O error when trying to recall the file
with a DMAPI 3rd party.

Platforms affected:
RHEL8 (x86_64, Power) and RHEL9 (x86_64, Power, Z)

Functional Area affected:
DMAPI

Customer Impact:
Critical
