Our servers have multiple HBAs. We now have multipath storage available and would like to reconfigure the system to take advantage of the additional paths. How can this be done?
The system was configured to boot from SAN, we don’t have disks on the servers. During OS installation root lvm/filesystem were created using sub paths: /dev/sdxx
Is it possible to migrate from single path /dev/sdxx to device-mapper-multipath devices viz. /dev/mapper/mpathX after OS installation??
LV VG Attr LSize Devices
LogVol00 rootvg -wi-ao 6.00G /dev/sdbt2(0) <--- root lvm volume created using underlying sub path
LogVol01 rootvg -wi-ao 10.00G /dev/sdbt2(352)
LogVol02 rootvg -wi-ao 5.00G /dev/sdbt2(674)
