Type: vgchange –a n /dev/vgdemo

Volume group "/dev/vgdemo" has been successfully changed.

You would now capture the replay of this LUN on the Dell Compellent Storage Center (as will be

discussed in the section below). When complete you would reenable I/O (writes) to the Volume Group

with the command “vgchange –a y /dev/vgdemo”.

Capturing the Snapshot

With the Volume Group quisced, we would now identify the LUN on the Dell Compellent Storage Center

and capture a replay of this LUN.

In this case, the LUN has been identified as “DanPreTest106” as matched by its serial number. We

would right-Click on the LUN, select the “Replay” link and then the “Create Replay” option.

In this subsequent dialog, we have chosen to expire this replay in 4hrs (user configurable) and named

the replay “Replay Jan 2012” (user definable field). We now left-click on the “Create Now” button to

capture the replay.
