  • Configured multipath for the Dell MD3660fc storage device and connected to 4 RHEL 5.9 servers but running multipath it returns this error:
multipath.conf line 25, invalid keyword: prio
  • The multipath.conf file looks like this:
defaults {
        user_friendly_names yes
        max_fds max
        polling_interval        5

devices {
        device {
                vendor                  "3PARdata"

  • After editing multipath.conf for new storage array, multipath retuns error message multipath.conf line XX, invalid keyword: XYZ. What need to be reviewed?
