The text installation of Red Hat Enterprise Linux 7.2 hangs with "started automated installation...."

Solution In Progress - Updated -

Environment

Red Hat Enterprise Linux 7.2

Issue

  • The installation of Red Hat Enterprise Linux 7.2 hangs with the following message.
started automated installation..............
  • Using the repository via NFS
  • Using kickstart file
  • One disk with hpsa driver is attached.

Resolution

Remove the following command from the kickstart file.

dd if=/dev/zero of=/dev/sda count=1

Root Cause

The %pre section in the kickstart file has the following:

dd if=/dev/zero of=/dev/sda count=1

With this command, the format on sda was corrupted. But, the udev information for partitions on sda had already been collected, and the installer tried to get the partitions information on sda, but it's not available. sda didn't have any partition table by the above command. The installation failed, because the device sda including the partition sda1 informed by udev didn't have a partition table.

As another cause, the installer could not get the package group information from nfs repository. This is still on investigation.
