OK,
That goes with VG, see which VG is shared, when you run
lspv
Few VG's show concurrent and few active, the concurrent one's are shared between the nodes in cluster.

The VGs (single or multiple) are combined to form a Resource Group (RG) and that is defined in the cluster.

You cannot failover a single filesystem, it has to be the RG.

If this is a production server DO NOT play around doing failover or fallback.

scds_fm_sleep(3HA)					 Sun Cluster HA and Data Services					scds_fm_sleep(3HA)

NAME
scds_fm_sleep - wait for a message on a fault monitor control socket SYNOPSIS
cc [flags...] -I /usr/cluster/include file -L /usr/cluster/lib -l dsdev #include <rgm/libdsdev.h> scha_err_t scds_fm_sleep(scds_handle_t handle, time_t timeout DESCRIPTION
Thescds_fm_sleep() function waits for a data service application process tree that running under control of the process monitor facility to die. If no such death occurs within the specified timeout period, the function returns SCHA_ERR_NOERR. If a data service application process tree death occurs, scds_fm_sleep() records SCDS_COMPLETE_FAILURE in the failure history and either restarts the process tree or fails it over according to the algorithm described in the scds_fm_action(3HA) man page. If a failover attempt is unsuccessful, a restart of the application is attempted. If an attempted restart fails, the function returns SCHA_ERR_INTERNAL. Note that if the failure history causes this function to do a failover, and the failover attempt succeeds, scds_fm_sleep() never returns. PARAMETERS
The following parameters are supported: handle The handle returned from scds_initialize(3HA). timeout The timeout period measured in seconds. RETURN VALUES
The scds_fm_sleep() function returns the following: 0 The function succeeded. nonzero The function failed. ERRORS
SCHA_ERR_NOERR Indicates that the process tree has not died. SCHA_ERR_INTERNAL Indicates that the data service application process tree has died and failed to restart. Other values Indicate the function failed. See scha_calls(3HA) for the meaning of failure codes. FILES
