RHEL dependency on host bus adapter (HBA) WWN or WWID?

Solution Unverified - Updated -

Issue

  • For boot from SAN servers or those with file systems from SAN, does RHEL handle change of WWID/WWN of host bus adapter (HBA) seamlessly/automatically?.

For example, if the HBA is faulty and replaced with different WWID/WWN, and assuming SAN zoning is updated and no change in disk WWID/WWN, does RHEL automatically detect the assigned SAN disks and proceed to boot up without making changes in some configuration files?.

Environment

  • Red Hat Enterprise Linux (RHEL)
