2. HDLM Functions

Figure 2-10: Path Switching
(2) Automatic Failbacks
When a path recovers from an error, HDLM can automatically place the recovered
path back online. This function is called the automatic failback function.
In order to use the automatic failback function, HDLM must already be monitoring
error recovery on a regular basis.
When using the Thunder 9500V series, or Hitachi AMS/WMS series, HDLM will
select the next path to be used first from among the online owner paths, and then from
the online non-owner paths. As a result, if an owner path recovers from an error, and
then HDLM automatically places the recovered path online while a non-owner path is
in use, the path will be automatically switched over from the non-owner path to the
owner path that just recovered from the error.
