Use this procedure to detach a storage array from a single cluster node, in a cluster that has three-node or four-node connectivity.
The phys-schost# prompt reflects a global-cluster prompt. Perform this procedure on a global cluster.
This procedure provides the long forms of the Oracle Solaris Cluster commands. Most commands also have short forms. Except for the long and short forms of the command names, the commands are identical.
phys-schost# clresourcegroup status phys-schost# cldevicegroup status
Caution (SPARC only) - If your cluster is running Oracle RAC software, shut down the Oracle RAC database instance that is running on the node before you move the groups off the node. For instructions, see the Oracle Database Administration Guide. |
phys-schost# clnode evacuate node
The clnode evacuate command switches over all device groups from the specified node to the next-preferred node. The command also switches all resource groups from the specified node to the next-preferred node.
For the procedure on putting a device group in maintenance state, see How to Put a Node Into Maintenance State.
If you use a raw disk, use the cldevicegroup(8CL) command to remove the device groups.
phys-schost# clresourcegroup remove-node -n node + | resourcegroup
See the Planning and Administering Data Services for Oracle Solaris Cluster 4.4 for more information about changing a resource group's node list.
Otherwise, skip this step.
If you are removing the host adapter from the node that you are disconnecting, skip to Step 11.
For the procedure on removing host adapters, see the documentation for the node.
phys-schost# pkg uninstall /ha-cluster/library/ucmm
Caution (SPARC only) - If you do not remove the Oracle RAC software from the node that you disconnected, the node panics when the node is reintroduced to the cluster and potentially causes a loss of data availability. |
On SPARC based systems, run the following command.
ok boot
On x86 based systems, run the following commands.
When the GRUB menu is displayed, select the appropriate Oracle Solaris entry and press Enter.
phys-schost# devfsadm -C phys-schost# cldevice refresh
