Bug ID 23699011
Issue: Oracle Linux L6.7 boots with the first enumerated volumes with the matched Logic Volume ID. If several Linux volumes are installed on the same system, they share the same LVID (lv_root_<HOST-Domain-Name>). The HOST-Domain-Name is automatically generated with the DHCP IP address, by default.
Affected software: Oracle Linux 6.7
Workaround: For best practice, do not install multiple Linux volumes with the same HOST-Domain-Name on the same server.
