      * Previously, when persistent volumes (PVs) are deleted, the Local Storage Operator (LSO) did not reliably recreate the symlinks to local devices. With this release,  when creating PVs, previously specified symlinks are picked before finding new symlinks. (link:https://issues.redhat.com/browse/OCPBUGS-31059[OCPBUGS-31059])

      Description of problem:

      The problem is I have existing PV's in use by ODF. These were created on LSO version before 4.13 and point to scsi-* are are referenced by the PV it created. That PV refers to the symlink to scsi for that drive.  After upgrade to v4.13 and v4.14 the LSO prefers wwn-* and appears to ignore the scsi-* path.  If a PV is deleted, the LSO does not recreate the PV's despite a the symlink to a scsi device path existing. It is only performing PV creation on wwn- symlinks.
This is a slow moving but huge mess since I have maintenance work and breakfix across thirty clusters and if a device is replaced or a PV is deleted it's not recreated until I debug the node and remove the symlink for that device/PV.

      Version-Release number of selected component (if applicable):

      How reproducible:

          Always

      Steps to Reproduce:

          1. Create LSO PVs on version prior to 4.13 using scsi device paths
    2. Upgrade to 4.13+
    3. Delete a PV. The LSO does not recreate the PV despite there being a scsi-* symlink.

      Actual results:

      No PV re-created

      Expected results:
