All the /dev/sda1,2,3 partitions vanish in /dev. The mounts work with
UUID. partprobe creates all the appropriate devices again.
Choose the older kernel (newest is kernel-3.10.0-693.21.1.el7.x86_64.
Older is kernel-3.10.0-693.5.2.el7.x86_64). Same scenario.

Sounds like an udev rule changed, causing the initial device to be
created in /dev/disk/ or similar instead of /dev/.

Other systems running older kernel only do not show this behavior.
Multipathd?
</blockquote>
Hmm. Possible. If multipath picks up a device first, it won't get
processed the regular way. I've disabled multipath before for this
reason. (Blacklisted the module -- if you actually need it, you'll have
to dig into its conf files.)

pvcreate wants a /dev/sdXN device which don't actually work. Ideas??
</blockquote>
pvcreate should be happy with /dev/disk/* link and will generally then
work no matter where or what name that device gets in the future.

gain at one end you lose at the other. It's like feeding a dog on his
