How do I change the order of storage devices during boot in RHEL 7?

Solution Verified - Updated -

Issue

  • The system is having internal RAID disk and few SAN devices. Sometimes, after a reboot /dev/sda name is assigned to SAN devices. How to force /dev/sda name for internal disk?

  • As per the article How do I change the order of storage devices during boot in RHEL 5 and 6?, rdloaddriver kernel option could be used to change the order of storage devices during boot process, and to get /dev/sda name for internal disk. Can the same option be used in RHEL 7 as well?
