UX:vxfs fsdb: ERROR: V-3-20003: Cannot open /dev/vx/dsk/dg1/vol1: Operation not permitted

Cause
The system was part of 2 node VVR replication, where both nodes failed one after another, and went to primary primary state, Even after setting correct secondary node (server102) to primary = false, node 1 (server101) was not properly becoming primary.
Resolution
1. Detach rlink
[root@server101 ~]# vxrlink -g dg1 -f det to_dr
VxVM VVR vxrlink INFO V-5-1-6775 Rlink to_dr is not up-to-date. Before restarting replication a complete synchronization of the secondary data volumes must be performed.
2. Again set primary=true for node 1(server101). Make sure it's right primary before failure.
[root@server101 ~]# vxedit -g dg1 set primary=true RVG1
3. Start Full sync again, as we don't know where the replication was broke.
[root@server101 ~]# vxrlink -g dg1 -a att to_dr
VxVM VVR vxrlink WARNING V-5-1-3359 Attaching rlink to non-empty rvg. Autosync will be performed.
VxVM VVR vxrlink INFO V-5-1-3614 Secondary data volumes detected with rvg RVG1 as parent:
VxVM VVR vxrlink INFO V-5-1-6183 vol1: len=3145728000 primary_datavol=vol1
VxVM VVR vxrlink INFO V-5-1-3365 Autosync operation has started
4. Check vxprint again.
[root@server101 ~]# vxprint -qhtg dg1

5. Check FS details with fsdb to confirm proper operation.
