vxclustadm utility
The vxclustadm command provides an interface to the cluster functionality of
VxVM when VCS or HP Serviceguard is used as the cluster monitor. It is also called
during cluster startup and shutdown. In the absence of a cluster monitor,
vxclustadm can also be used to activate or deactivate the cluster functionality of
VxVM on any node in a cluster.
The startnode keyword to vxclustadm starts cluster functionality on a cluster
node by passing cluster configuration information to the VxVM kernel. In response
to this command, the kernel and the VxVM configuration daemon, vxconfigd,
perform initialization.
The stopnode keyword stops cluster functionality on a node. It waits for all
outstanding I/O to complete and for all applications to close shared volumes.
The reinit keyword allows nodes to be added to or removed from a cluster without
stopping the cluster. Before running this command, the cluster configuration file
must have been updated with information about the supported nodes in the cluster.
The nidmap keyword prints a table showing the mapping between CVM node IDs
in VxVM’s cluster-support subsystem and node IDs in the cluster monitor. It also
prints the state of the nodes in the cluster.
The nodestate keyword reports the state of a cluster node and also the reason
for the last abort of the node as shown in this example:
# /etc/vx/bin/vxclustadm nodestate
state: out of cluster
reason: user initiated stop
Table 13-5 lists the various reasons that may be given for a node abort.
