SVM metaset on 2 node Solaris cluster storage replicated to non-clustered Solaris node

Hi,

Is it possible to have a Solaris cluster of 2 nodes at SITE-A using SVM and creating metaset using say 2 LUNs (on SAN). Then replicating these 2 LUNs to remote site SITE-B via storage based replication and then using these LUNs by importing them as a metaset on a server at SITE-B which is not running Solaris cluster? Solaris OS versions on all 3 nodes (2 nodes at SITE-A and 1 node at SITE-B) is same.
This is to say can I have a solution having 2 nodes in a Solaris cluster at SITE-A and have DR by having a single non-clustered node at SITE-B using SVM metaset replicated via storage replication.

Thanks.

VOTEQUORUM_LEAVING(3)				    Corosync Cluster Engine Programmer's Manual 			     VOTEQUORUM_LEAVING(3)

NAME
votequorum_leaving - Tell other nodes that we are leaving the cluster SYNOPSIS
#include <corosync/votequorum.h> int votequorum_leaving(votequorum_handle_t handle); DESCRIPTION
The votequorum_leaving function is used to tell the other nodes in the cluster that this node is leaving. They will (when the node actually leaves) reduce quorum to keep the cluster running without this node. This function should only be called if it is known that the node is being shut down for a known reason and could be out of the cluster for an extended period of time. Normal behaviour is for the cluster to reduce the total number of votes, but NOT expected_votes when a node leave the cluster, so the clus- ter could become inquorate. This is correct behaviour and is ther eto prevent split-brain. Do NOT call this function unless you know what you are doing. RETURN VALUE
This call returns the CS_OK value if successful, otherwise an error is returned. ERRORS
The errors are undocumented. SEE ALSO
