Red Hat Multipathing • /etc/multipath.conf – basic configuration file • Created and maintained by the multipath program • /etc/multipath/bindings • /etc/multipath/wwids • Both files contain wwid for each device with different entries for Site 1 and Site 2 different physical device • Site1 360000970000192601700533030383737 • Site2 360000970000192601715533030333032
Use LVM with Replicated Copies • LVM masks the changing SCSI multipath information • Volume groups (VG) are made up of LVM physical volumes (PVs) • LVM physical volumes are identified by PV UUID, not multipath device UUID/WWID • Logical volumes(LVs) are associated to LVM volume groups • Filesystems are associated to logical volumes in /etc/fstab • All LVM entities are found, brought online and the filesystem mounted at Site 2, no different than Site 1
