EMC PowerPath storage stops activating on boot

Solution Verified - Updated -


  • System previously mounting EMC PowerPath storage on boot, with LVM volumes defined in the LUNs, stops mounting the volumes on boot.
  • With the root filesystem on local storage, you are able to manually work around the issue by commenting out SAN storage in /etc/fstab, booting from local filesystem, starting the PowerPath service, uncommenting the storage mounts in /etc/fstab and running mount -a.
  • The EMC PowerPath devices are missing after upgrade system
