vxfs_vol_resize - resize a specific volume within a multi-volume file system
cc -I /opt/VRTS/include -L /opt/VRTS/lib-l vxfsutil -ldl#include <sys/types.h>

int vxfs_vol_resize(int fd, char *volname, uint64_t newsize);

vxfs_vol_resize() changes the amount of space available to a file system in a component volume specified by the volume volname. The size of the new component volume must be at least newsize (specified in bytes). The file descriptor fd can be any file in the file system.
In the current implementation, if there is data in the part of the volume that is shrinking, the resize operation will fail.
vxfs_vol_resize() returns zero on success, non-zero on failure.
ENOSPC There was not enough space to expand the structural files to represent the new blocks in the device. EPERM The calling process does not have correct access privileges. ENXIO An I/O error occurred during operation.
