Hi every body
My customer has two fas2040 system,
He want me to help him to create Synchronous SnapMirror,
but if I use OnCommand System Manager or FilerView to create Snapmirror,
It always can create only Async Snapmirror,
how to create Synchronous SnapMirror?
is any implement guide?
it can use GUI to create?
or I must use CLI or must to edit config file to create?
See The Solution
assuming you have all you licensing in place and have set up the source and destination volumes you need to create the snapmirror relationship either through the gui or cli
(snapmirror initialize -S src:vol1 dst:vol2)
Then you need to edit (or create) the /etc/snapmirror.conf file on the destination netapp to configure the ongoing relationship and specify it as synchronous:
src:vol1 dst:/vol2 - sync
you basically replace the schedule with the word sync (as above) and youre done,
hope this helps,

Thank for your answer,
but I want as that if the synchronous snapmirror support 1Gb Gigabit Ethernet?
or it must use FC?
there is no requirement to use FC but you must consider latency. Latency will go up the further apart the Netapps are.
You can consider using dedicated nics or even Multiplexing (multipathing) to load balance the bandwidth - for this you will need 2 nics on each netapp
here is a blog that explains how to set it up:
