Changing the Activation Mode on a Shared Disk
Group
NOTE The activation mode for access by a cluster node to a shared disk group is
set on that node.
The activation mode of a shared disk group can be changed using the
following command:
# vxdg -g diskgroup set activation=mode
The activation mode is one of exclusive-write or ew, read-only or ro,
shared-read or sr, shared-write or sw, or off. See “Activation Modes
of Shared Disk Groups” on page 355 for more information.
Setting the Connectivity Policy on a Shared Disk
Group
NOTE The connectivity policy for a shared disk group can only be set on the
master node.
The vxedit command may be used to set either the global or local
connectivity policy for a shared disk group:
# vxedit -g diskgroup set diskdetpolicy=global|local
diskgroup
See “Connectivity Policy of Shared Disk Groups” on page 358 for more
