Use the Shutting Down Node panel in the SAN Volume Controller Console shut
down the node.
Introduction
If
all input power to a SAN Volume Controller cluster
uninterruptible power supply units is removed, the cluster automatically
shuts down in a controlled fashion. This power removal is a normally
scheduled maintenance activity. In this case, the cluster shuts down
in a controlled fashion using the Cluster Shutdown panel. This process
stops the host I/O to the cluster and ensures that all of the host
file systems are cleanly flushed to the SAN Volume Controller,
rather than allowing the uninterruptible power supply units to instruct
the cluster to power down on the loss of input power.
Attention: Never remove power directly from a SAN Volume Controller node
while it is an active member of the cluster. Shut down the node first.
Attributes
The
following attributes are displayed in the table:
- Name
- Displays the name that is assigned to this node. If you have not
yet assigned a name, a default name is assigned. The default name
is the string node followed by the system-assigned
ID. You can click on the link in this column to display detailed information
about the node.
- State
- Displays the current state of the node. The following values are
possible:
- Adding
- Indicates that the node has been added to the cluster but is not
synchronized with the state of the cluster.
- Deleting
- Indicates that the cluster is in the process of deleting the node.
Any VDisk-to-host mappings and Copy Services interactions are being
deleted.
- Flushing
- Indicates that the node is clearing its cache.
- Online
- Indicates that the node is operational, assigned to a cluster,
and has access to the fibre-channel storage area network (SAN) fabric.
- Offline
- Indicates that the node is not operational. The node has been
assigned to a cluster but is not available on the fibre-channel SAN
fabric. Run the directed maintenance procedures to determine the problem.
- WWNN
- Displays the worldwide node name.
- I/O Group Name
- Displays the name of the I/O group that this node belongs to.
The default name is the string io_grp, which is followed
by the system-assigned ID.
- Configuration Node
- Indicates whether this node is the configuration node for the
cluster. The following values are possible:
Actions
The
following actions are available:
- OK
- Click this button to shut down the node.
- Cancel
- Click this button to exit this panel without shutting down the
node.
