Functional Differences Between Version 5.7.0-01 or Later
and Versions Earlier Than 5.7.0-01
In versions earlier than 5.7.0-01, when an I/O request is sent to a path in the
Online(E) status despite all paths being disconnected, the status of the path
is changed to Offline(E) and another path is placed in the Online(E)
status. In version 5.7.0-01 or later, even if an I/O request is sent to a path in
the Online(E) status, the status of the path does not change.
In the event of path recovery after all paths have failed, the paths must be
placed online by automatic failback or by using a command before you can
access the data.
Functional Differences Between Version 5.7 or Later and
Versions Earlier Than 5.7
In version 5.7 or later, if there are no files under the /etc/opt/
