The answer is no!
But since sometimes taking somebodies word for something
is not enough, here we demonstrate this with a simple experiment.
We have a 7-Mode system NA01. We have a C-Mode cluster
NACLU1. We have two Vservers - SVM1 and SVM1B. We create a 7-Mode volume
migTest01, TDP SnapMirror it to SVM1, then try DP SnapMirror-ing that to SVM1B.
This is the result:
1) Creating a 7-Mode volume with one qtree:
NA01>
vol create migTest01 -l en -s none aggr1 2g
NA01>
qtree create /vol/migTest01/tree1
2) Enabling SnapMirror to the cluster (which has an
intercluster LIF on 192.168.168.113):
NA01>
options snapmirror.access host=192.168.168.113
3) Create the volume on CDOT, and setup the TDP
SnapMirror:
NACLU1::>
vol create -vserver SVM1 -volume migTest01 -aggregate aggr1 -size 2g -language
en -space-guarantee none -type DP
NACLU1::>
vserver peer transition create -local-vserver SVM1 -src-filer-name
192.168.168.101
NACLU1::>
snapmirror create -source-path 192.168.168.101:migTest01 -destination-path
SVM1:migTest01 -type TDP -schedule hourly
NACLU1::>
snapmirror initialize -destination-path SVM1:migTest01
4) Verify the Qtree created in 1 has come across, and
display the is-copied-for-transition status:
NACLU1::>
qtree show -volume migTest01
Vserver Volume Qtree Style Oplocks Status
----------
------------- ------------ ------------ --------- --------
SVM1 migTest01 "" unix enable readonly
SVM1 migTest01 tree1 unix enable readonly
NACLU1::>
set -confirmations off
NACLU1::>
set d
NACLU1::*>
volume show -is-copied-for-transition true -fields is-copied-for-transition
vserver
volume is-copied-for-transition
-------
--------- ------------------------
SVM1 migTest01 true
5) Then configure SnapMirror from the “is-copied-for-transition”
volume to SVM1B:
NACLU1::>
vserver peer create -vserver SVM1 -peer-vserver SVM1B -applications snapmirror
NACLU1::>
vol create -vserver SVM1B -volume migTest01 -aggregate aggr1 -size 2g -language
en -space-guarantee none -type DP
NACLU1::>
snapmirror create -source-path SVM1:migTest01 -destination-path SVM1B:migTest01
-type DP -schedule hourly
Operation
succeeded: snapmirror create for the relationship with destination
"SVM1B:migTest01".
NACLU1::>
snapmirror initialize -destination-path SVM1B:migTest01
Error: command
failed: Failed to get information for source volume "SVM1:migTest01"
for confirmation. (Source "SVM1:migTest01" is a transition volume.
Using a transition volume as a SnapMirror source volume is not supported.)
And the above is our error!
