Description of problem:
We're following the HA guide from here:
https://access.redhat.com/documentation/en-us/red_hat_cloudforms/4.2/html-single/configuring_high_availability/

When configuring the secondary database appliance, the appliance_console does not ask which disk has to be used and consequently doesn't configure it.

Version-Release number of selected component (if applicable):
5.7

How reproducible:
always

Steps to Reproduce:
1. follow the HA guide
2. setup a primary database
3. setup a secondary database

Actual results:
when configuring the replication settings, select "secondary database server". Unlike the primary, this does not ask which disk has to be used for the database and consequently doesn't confiugre it. 

The database is still configured correctly and works fine, but the database is stored on the root file system and not on a dedicated disk.

Expected results:
when setting up the secondary DB, it should ask which disk has to be configured for the database
