Event
When LPAR migration fails because of an error or cancelled because of
resource shortage or any other cause on the destination, an error message is
displayed in Migration Progress window and recovering LPAR is often executed
automatically. However, there are some cases which are recovered
automatically depending on the kind of errors or the states of HVM or LPAR
configurations in a momentary time which the error occurs.
In such a case, recover all LPARs necessary to be recovered and execute LPAR
migration again.
If the automatic recover explained above fails, recover LPARs according to the
procedure in "Solution" below.
