For example, in a normal state, I/O operations are not performed on the
paths coming from the standby host in the cluster configuration or on non-
owner paths (that is, some of the paths that access a Thunder 9500V series
and Hitachi AMS/WMS series storage system). Because of this, for the
standby host or for a host connected to non-owner paths, we recommend
that you use path health checking to detect errors. This enables the system
to use the most up-to-date path-status information when selecting the next
path to use.
You can configure path health checking by executing the dlnkmgr command's
set operation. For details on the set operation, see
Operating Environment) on page
