Changes made to global device permissions are not automatically propagated to all the nodes in the cluster for Solstice DiskSuite/Solaris Volume Manager and disk devices. If you want to change permissions on global devices, you must manually change the permissions on all the nodes in the cluster. For example, if you want to change permissions on global device /dev/global/dsk/d3s0 to 644, you must execute
# chmod 644 /dev/global/dsk/d3s0
on all nodes in the cluster.
VxVM does not support the chmod command. To change global device permissions in VxVM, consult the VxVM Administrator's Guide.
