Below is a slight change to RudiC's solution to also print the line following the LUN:

Code:
awk '
/^LUN/          {LUN = $0 
                 getline
                 LUN=LUN "\n" $0 
                }
/round-robin/   {RRO = $0 }
/failed/        {if (LUN) print LUN
                 if (RRO) print RRO
                 LUN = RRO = ""
                 print
                }
'  /tmp/mpfail

Output:

Code:
LUN06 (3600507680180856b180000000000067f) dm-11 IBM,2145
