The SMP device is a pseudo device for the snapshot and assumes the SCSI personality of the snapshot that is being created. Thus VolumeXXX7 is created from the SMP device hence why you see the writes going to the SMP device and why the SMP device and VolumeXXX7 are created simultaneously. This next replication will show the SMP device linked to snapshot VolumeXXX8.

Hello, When the CG is configured, I see RP creating 3 snaps on XIO at the DR site. The first snap is a readonly snap named like VolumeXXX6, and then like 4 seconds later 2 snapshots are taken simultaneously, one named with suffix _SMP, and the other named like VolumeXXX7. One of these newly taken snaps (Volume XXX7)  is readonly as well, and all the new writes during initial synchronizarion are being written to the snap with suffix _SMP. What is the purpose of those readonly snaps (VolumeXXX6 and VolumeXXX7)? Also, do we see 3 snapshots being taken all the time at the DR copy, instead of one?
