How to Remove a Node From a Raw-Disk Device Group
Use this procedure to remove a cluster node from the list of potential primaries of a raw-disk device group.
The phys-schost# prompt reflects a global-cluster prompt. Perform this procedure on a global cluster.
This procedure provides the long forms of the Sun Cluster commands. Most commands also have short forms. Except for the long and short forms of the command names, the commands are identical. For a list of the commands and their short forms, see Appendix B, Sun Cluster Object-Oriented Commands.
-
Become superuser or assume a role that provides solaris.cluster.read and solaris.cluster.modify RBAC authorization on a node in the cluster other than the node to remove.
-
Identify the device groups that are connected to the node being removed, and determine which are raw-disk device groups.
# cldevicegroup show -n nodename -t rawdisk +
-
Disable the localonly property of each Local_Disk raw-disk device group.
# cldevicegroup set -p localonly=false devicegroup
See the cldevicegroup(1CL) man page for more information about the localonly property.
-
Verify that you have disabled the localonly property of all raw-disk device groups that are connected to the node being removed.
The Disk device group type indicates that the localonly property is disabled for that raw-disk device group.
# cldevicegroup show -n nodename -t rawdisk -v +
-
Remove the node from all raw-disk device groups that are identified in Step 2.
You must complete this step for each raw-disk device group that is connected to the node being removed.
# cldevicegroup remove-node -n nodename devicegroup
Example 5–30 Removing a Node From a Raw Device Group
This example shows how to remove a node (phys-schost-2) from a raw-disk device group. All commands are run from another node of the cluster (phys-schost-1).
