I found the issue on IBM power9 server. But I guess the issue exists all arches. Typo fixed. Verified on device-mapper-multipath-0.8.4-17.el8
[root@ibm-p9z-20-lp13 ~]# rpm -qa | grep multipath
device-mapper-multipath-libs-0.8.4-17.el8.ppc64le
device-mapper-multipath-0.8.4-17.el8.ppc64le
[root@ibm-p9z-20-lp13 ~]# man multipath.conf
checker_timeout Specify the timeout to use for path checkers and prior-
itizers, in seconds. Only prioritizers that issue scsi
commands use checker_timeout. Checkers that support an
asynchronous mode (tur and directio), will return
shortly after being called by multipathd, regardless of
whether the storage array responds. If the storage
array hasn't responded, multipathd will check for a
response every second, until checker_timeout seconds
have elapsed.
The default is: in /sys/block/sd<x>/device/timeout
