Veritas Storage Foundation 5.1 SP1 Cluster File System Administrator"s Guide (5900-1738, April 2011)

To check the connectivity of CP server
Run the following command to check whether a CP server is up and running
at a process level:
# cpsadm -s cp_server -a ping_cps
where cp_server is the virtual IP address or virtual hostname on which the
CP server is listening.
Issues during online migration of coordination points
During online migration of coordination points using the vxfenswap utility, the
operation is automatically rolled back if a failure is encountered during validation
of coordination points from all the cluster nodes.
Validation failure of the new set of coordination points can occur in the following
circumstances:
The /etc/vxfenmode file is not updated on all the SFCFS cluster nodes, because
new coordination points on the node were being picked up from an old
/etc/vxfenmode file.
The coordination points listed in the /etc/vxfenmode file on the different
SFCFS cluster nodes are not the same. If different coordination points are
listed in the /etc/vxfenmode file on the cluster nodes, then the operation fails
due to failure during the coordination point snapshot check.
There is no network connectivity from one or more SFCFS cluster nodes to the
CP server(s).
Cluster, nodes, or users for the SFCFS cluster nodes have not been added on
the new CP servers, thereby causing authorization failure.
Vxfen service group activity after issuing the vxfenswap
command
After issuing the vxfenswap command, the Coordination Point agent reads the
details of coordination points from the vxfenconfig -l output and starts
monitoring the registrations on them.
During vxfenswap, when the vxfenmode file is being changed by the user, the
Coordination Point agent does not move to FAULTED state but continues
monitoring the old set of coordination points.
As long as the changes to vxfenmode file are not committed or the new set of
coordination points are not re-elected in vxfenconfig -l output, the Coordination
