I assume that a workaround would be to enter the installer shell and manually wipe out the device (using wipefs) and to redo the install afterwards.
Since it's quite late in the cycle, I've marked this bug as affecting the 'release notes' and leaving a known issue msg there.

  devices

  Confirmed
Status in Release Notes for Ubuntu:

Bug description:
  When attempting to install Groovy to a zVM (s5lp1-gen02) the Subiquity
  installer reports an error after fcp devices are selected and the
  partition layout is confirmed. The iso image used was from October 21,
  2020. Dropping to the shell the following traceback is found in
  /var/log/syslog:
