Last week I performed an upgrade in place on one of my virtual servers that run under z/VM 6.4. I upgraded from SLES 11 SP4 to SLES 12 SP2.
My servers are all set up with at least 2 swap disks. One is a small (256MB) virtual swap disk and a 3390 mod9 (7048MB) swap disk. The virtual swap disk is supposed to be the primary disk. After the upgrade the physical disk is the primary, but /etc/fstab shows that it should not be.

Any idea why SLES 12 is not honoring the values specified in /etc/fstab? What setting(s) do I need to modify to have the swap priorities set as specified in /etc/fstab?
