Functional Differences Between Version 5.7.1 or Later and

Versions Earlier Than 5.7.1

In versions earlier than 5.7.1, if the HDLM driver fails to allocate memory for

an I/O operation when reading or writing from the HDLM device, it returns an

error instead of retrying.

In version 5.7.1 or later, the system tries to allocate the memory again and

the I/O operation is executed successfully. The number of retries can be set

by the user. By default, the system retries the operation until memory is

allocated.

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.
