Upgrade precheck by using the installation toolkit might fail on protocol nodes in an ESS environment

The installation toolkit upgrade precheck might fail on protocol nodes in an Elastic Storage Server (ESS) environment due to versionlocks being set on certain packages.

If a protocol node is provisioned through xCAT in an ESS environment, versionlocks are set on certain key packages. If the OS is then upgraded on the node and then the installation toolkit is used for an upgrade precheck, the precheck might fail.

Workaround:
  1. View the list of versionlocks.
    yum versionlock status
  2. Clear the versionlocks.
    yum versionlock clear
  3. Rerun the upgrade precheck.
    ./spectrumscale upgrade precheck
