Changing the activation mode on a shared disk group
The activation mode for access by a cluster node to a shared disk group is set directly 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 exclusivewrite or ew, readonly or ro, sharedread or sr, sharedwrite or sw, or off.
If you use this command to change the activation mode of a shared disk group, you must first change the activation mode to off before setting it to any other value, as shown here:
# vxdg -g myshdg set activation=off
# vxdg -g myshdg set activation=readonly
