            Bug ID: 221119
           Summary: FreeBSD FC SAN path failover time exceeds 60s
           Product: Base System
           Version: 11.1-RELEASE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: kern
          Assignee: freebsd-bugs@FreeBSD.org
          Reporter: steel.liu@huawei.com

Qlogic qle2562 was installed on FreeBSD 11.1 host. Two ports are connected =
to
storage array controllers respectively.
Multipath was enabled and each LUN has 2 paths to the storage array. When we
disconnected one FC port to the storage array, the multipath failover to the
second path. But the failover time exceeds 60s.

We think 60 seconds is too long to result some application timeout or error=
. I
hope to know if there're some settings we can use to reduce the failover ti=
me.=20

Thanks
