</span></strong><span style="font-size:9.0pt"><o:p></o:p></span></p>
<p><span style="font-size:9.0pt">IBM has identified a problem in IBM Spectrum Scale V4.1.1.0 through 5.0.1.1, in which under some conditions reading a DMAPI-migrated file may return zeroes instead of the actual data. Further, a DMAPI-migrate operation or writing
to a DMAPI-migrated file may cause the size of the stub file to be updated incorrectly, which may cause a mismatch between the file size recorded in the stub file and in the migrated object. This may result in failure of a manual or transparent recall, when
triggered by a subsequent read from or write to the file. <o:p></o:p></span></p>
