[Bug 1723541] Re: zVM 17.10 install: LVM installation results in IPL UNIT ERROR

[Phillip Wilson]

I just ran into this problem during a standard update.  It seems very
similar but I thought I would post it here.  My system is running within
an LPAR with no z/VM.  Below are the messages I receive.

  zVM 17.10 install: LVM installation results in IPL UNIT ERROR

Bug description:
  [Impact]

  zipl uses zipl_helper.device-mapper helper perl script to determine underlying device geometry/layout to create the bootmap records, when rootfs is on LVM / multipath devices.
  That script calls dasdview to get the geometry of the DASD drives using deprecated -f options, which is now redundant given that device argument is now simply positional and required. With that flag, dasdview now exits with failure and the zipl_helper.device-mapper tool uses incorrect built-in fallback defaults, which are most likely wrong.

  Without this fix installing onto multipath devices, or root on LVM
  (default) is not possible.


  If 'use entire disk and set up LVM' is selected during installation of
  a zVM guest, the system fails to IPL with the error:

  LOGON GENRL04

  DASD devices were configured in this instance.
  The error is not seen when non-LVM partitioning is selected (e.g. User entire disk).
