clu_is_ready
clu_is_member(3) Library Functions Manual clu_is_member(3)NAME
clu_is_member, clu_is_ready - Determine whether the local system is currently a cluster member or has been configured to be a cluster mem-
ber
LIBRARY
Standard C Library (libc.so, libc.a)
SYNOPSIS
#include <sys/clu.h>
boolean_t clu_is_member ();
boolean_t clu_is_ready ();
DESCRIPTION
The clu_is_member function determines whether the local system is currently a cluster member (that is, the TruCluster Server software has
been installed and configured, the system has booted a clusterized kernel, and the connection manager has allowed the system to join the
cluster membership).
The clu_is_ready function determines whether the local system has been configured to run in a cluster (that is, the TruCluster Server soft-
ware has been installed and configured, and the system has booted a clusterized kernel). The clu_is_ready function is most useful to code
that runs in the boot path before the connection manager establishes the cluster membership.
RETURN VALUES
Upon completion, the clu_is_member function returns TRUE if the local system is currently a cluster member, FALSE otherwise.
Upon completion, the clu_is_ready function returns TRUE if the local system has booted from a clusterized kernel, FALSE otherwise.
