The upgrade to SP3 appears to cause a change in the udev definitions for the DASD defined on the server (in /etc/udev/rules.d) . For SLES 12 systems, these rules are 51-dasd-0.0.0xxx.rules files but it seems that for SLES15, they change format and number to 41-dasd-eckd-0.0.0xxx.rules.
This change actually happened with SLES12 SP4, when the chzdev and lszdev tools were introduced to s390-tools by IBM.
However, this change does not happen for an upgraded SLES12 system to SLES15 until you upgrade to SLES15SP3. Once you upgrade to SP3, then the old 51-dasd rules are renamed with the '.legacy' extensions, new 41- rules are created. The rules for the vdisk for swap are left alone and thus after the upgrade, the swap partitions are no longer activated. There is more to this but I will not go into detail.
Question, for each of the udev rules renamed to .legacy, is there an equivalent 41-* rule present?
