Variables for Plug-in Component "sunCluster"

Variables for Plug-in Virtual Hosts of Type "clusterNode"

clusterHost

This variable MUST be set to the name of the virtual N1SPS host of type "cluster" for the cluster to which this node belongs.

privateNetAdapter_1

This variable can be set by this virtual host or as a "sunCluster" component variable. It must be set in one of the two. If
it is set in both, this host setting is used.

This variable specifies the network adapter (NIC) on each node for the first private network.

This variable is passed to scinstall for use with the "-A name=" setting. Refer to the scinstall(1M) man page for details.

privateNetAdapter_2

This variable can be set by this virtual host or as a "sunCluster" component variable. It must be set in one of the two. If
it is set in both, this host setting is used.

This variable specifies the network adapter (NIC) on each node for the second private network.

This variable is passed to scinstall for use with the "-A name" setting. Refer to the scinstall(1M) man page for details.

Variables for Plug-in Virtual Hosts of Type "cluster"

clusterName

This variable is the name of this cluster.

This variable is passed to scinstall for use with the "-C" option. Refer to the scinstall(1M) man page for details.

By default, the name of the cluster will be set to the same name as this virtual N1SPS "cluster" host.

nodeList

This variable is the list of nodes to use when you create a new cluster.

By default, "automatic initialization" is used. The "scCreateCluster" plan automatically creates a node list for each cluster
when it runs the "scInstallPackages" sub-plan.

But, this variable allows you to override this default behavior with an explict list of nodes. If you specify an explicit node
list, separater the node names by commas.

You do not need to override the default unless you want to do so for providing a record in N1SPS.

quorumDevices

This variable is the list of quorum disk devices to use when creating new clusters and, optionally, when adding or removing
cluster quorum devices.

The list takes the format "nodename:device[,...] | did_device[,...]". That is, local Solaris device names can be
used, as long as they are prefixed with a "nodename:"

When you create a new cluster, if you do not provide a list of quorum disk devices, automatic quorum configuration will be
attempted for clusters of two nodes. Otherwise, no quorum disk devices will be configured.

Variables for Plug-in Component "sunCluster"

installPath

This variable is required by all N1SPS components of this type. However, it is not expressly used by this particular component
and should not be set.

nodeAuthentication

This variable takes the value of either "sys" or "des". The default setting is "sys". This variable is passed to scinstall
for use with the "-T authtype=" setting. Refer to the scinstall(1M) man page for details.

privateNetAdapter_1

This variable can be set by the component or by the "clusterNode" host. It must be set in one of the two. If it is set in both,
the "clusterNode" host setting is used.

This variable specifies the network adapter (NIC) on each node for the first private network.

This variable is passed to scinstall for use with the "-A name=" setting. Refer to the scinstall(1M) man page for details.

privateNetAdapter_2

This variable can be set by the component or by the "clusterNode" host. It must be set in one of the two. If it is set in both,
the "clusterNode" host setting is used.

This variable specifies the network adapter (NIC) on each node for the second private network.

This variable is passed to scinstall for use with the "-A name=" setting. Refer to the scinstall(1M) man page for details.

privateNetSwitch_1

This variable specifies the name of the switch for the first private network.

The default setting for this variable is "switch1". There should be no need to change the default.

This variable is passed to scinstall for use with the "-B name=" setting. Refer to the scinstall(1M) man page for details.

privateNetSwitch_2

This variable specifies the name of the switch for the second private network.

The default setting for this variable is "switch2". There should be no need to change the default.

This variable is passed to scinstall for use with the "-B name=" setting. Refer to the scinstall(1M) man page for details.

privateNetAddress

This variable specifies the private network address for the private network.

The default setting for this variable is "172.16.0.0". This is a private network address and is not visible outside the cluster.
There is rarely any reason to change this default.

This variable is passed to scinstall for use with the "-w netaddr=" setting. Refer to the scinstall(1M) man page for details.

privateNetMask

This variable specifies the private network mask for the private network.

The default setting for this variable is "255.255.258.0". This is used only for the private cluster network and is not visible
outside the cluster. There is rarely any reason to change this default.

This variable is passed to scinstall for use with the "-w netmask=" setting. Refer to the scinstall(1M) man page for details.

globalDevicesFileSystem

This variable is passed to scinstall for use with the "-G" option. Refer to the scinstall(1M) man page for details.

The default setting for this variable is "/globaldevices". This setting requires that each host have an empty file system
that is created and mounted on /globaldevices.

Some, but not all, versions of Sun Cluster 3.2 software support an "lofi" setting for this variable. If supported in your
version of Sun Cluster software, set this variable to "lofi". The "lofi" option does not require a dedicated slice or file system.
