What To Do for a Path Error

When a path error is detected by HDLM, you must immediately resolve the
error and restore the path.
A path error check is performed every time an I/O is issued, or the Windows
plug-and-play functionality detects that a path is disconnected. If there are
any paths through which I/Os are not normally issued, such as a non-owner
path, you should enable path health checking in order to detect any possible
errors. For details about path health checking, see
Path Health Checking on page
When a path error is detected, HDLM performs a failover on the path and
outputs the KAPL08022-E message. This message indicates that an error has
occurred in the components that make up the path.
