Use this page to choose nodes to include in the new cluster.
A cluster node is a system unit that participates in an PowerHA™ SystemMirror cluster
as a server. A node can be an IBM® System p® system unit, or a
logical partition (LPAR) within a partitioned System p server system unit, that is running
a supported level of AIX® and
meets the minimum requirements for internal memory, internal disk,
and I/O slots.
All the nodes that you include in the cluster must meet the following
prerequisites:
- have the same version of AIX installed
- have the same version and edition of PowerHA SystemMirror installed
- have at least one storage disk in common among them
Fields
- Choose nodes
- The Choose nodes table lists the host names
of all available nodes that meet the prerequisites for inclusion in
a cluster. The table does not include any host names of nodes that
are already included in an existing cluster.
Select one or more
host names in the table that you want to include as nodes in the new
cluster. When you make the first selection, the entries in the table
are updated so that you cannot select host names that are not compatible
with the one you first selected. A minimum of two nodes are required
for the new cluster. The maximum number of nodes allowed for a cluster
is 32.
Actions
- Common Storage
- Click Common Storage in the Choose
Nodes table task bar or select this action from the Actions menu
to view a list of storage disks that are common to all selected nodes.
The selected nodes must have at least one storage disk in common among
them. A common storage disk must be available for use as the cluster
central repository, which contains configuration and other data for
the cluster. There must be at least one common storage disk common
among all the selected nodes or you cannot complete the wizard to
create the cluster.
