I wantto snapmirror my 2 TB volume whoch conatin luns to another filer . The volume is 100% full as it contains the luns . How much free space is required at the source to start the snampmirror of lun volumes ? Does starting snapmirror on lun volumes will have any impact on the source luns which are mapped on online ?

An Snapmirror based on a Snapshot. If your volume 100% full, you can't take a Snapshot for a Snapmirror.
You need enough space for the Snapshot.
The Snapmirror can create and initialized at any time.
You can create a throttle if your network is small.

Is volume really full?
Have you tried adjusting the f
Setting it to thin provisioned?
Setting dedup (does require some snap space), if only temporarily?
Deleting old snapshots, if any.
Starting a snapmirror should have no impact on source luns, they remain on-line and the SM process is transparent to the lun's client system.
It should be possible to SM a vol with very little free space, it's just slower if there's a lot of change going on.
