4.3 Actions taken for a path error

When a path error is detected by HDLM, you must immediately resolve the error and restore the path.

A check for path errors is performed whenever an I/O is issued, or the Windows Plug and Play function detects that the paths are disconnected. If there are any paths through which I/O is not normally issued, such as a non-owner path, you should enable path health checking in order to detect errors regardless of I/O issuance. For details on detecting errors by using path health checking, see the HDLM manual.

Figure 4-2 Troubleshooting procedure when a path error occurs shows the troubleshooting procedure when a message indicating that a path error has occurred is output.
