You can use the command-line interface (CLI) to shut down
a node.
Ensure that you stop all FlashCopy®,
Metro Mirror, Global Mirror, or data migration operations before you
attempt to shut down a node. You must also ensure that all asynchronous
deletion operations have completed. Also quiesce all I/O operations
that are destined for this node. Failure to do so can result in failed
I/O operations being reported to your host operating systems.
To shut down a node, follow these steps:
- To shut down a single node, issue the following command:
svctask stopcluster -node node_name or node_ID
Where node_name
or node_ID specifies the node name or the node ID that is
assigned to the node.
- To shut down the last node in an I/O group, issue the following
command.
Attention: You will lose all access
to the virtual disks (VDisks) in the I/O group. Before you enter this
command, ensure that this is what you want to do.
svctask stopcluster -force -node node_name or node_ID
When you enter the svctask stopcluster command
with no parameters, the entire cluster is shut down. All data is flushed
to disk before the power is removed.
