Thank you for your suggestion. I did not do it the way you suggested for
three reasons:

1) server B is a production server and I wanted to avoid as much downtime
as possible

2) server B is running with SAS drives and server A is running with SATA

3) I want to create a way to mirror the server B system to another hard
drive not just this one time but periodically also in the future in
automatized way
