How to Log Into the Cluster Remotely
The Cluster Control Panel (CCP) provides a launchpad for the cconsole, crlogin, cssh, and ctelnet tools. All tools start a multiple-window connection to a set of specified nodes. The multiple-window connection consists of a host window for each of the specified nodes and a common window. Input to the common window is sent to each of the host windows, enabling you to run commands simultaneously on all nodes of the cluster.
You can also start cconsole, crlogin, cssh, or ctelnet sessions from the command line.
By default, the cconsole utility uses a telnet connection to the node consoles. To establish secure shell connections to the consoles instead, enable the Use SSH checkbox in the Options menu of the cconsole window. Or, specify the -s option when you issue the ccp or cconsole command.
See the ccp(1M) and cconsole(1M) man pages for more information.
The phys-schost# prompt reflects a global-cluster prompt. Perform this procedure on a global cluster.
This procedure provides the long forms of the Sun Cluster commands. Most commands also have short forms. Except for the long and short forms of the command names, the commands are identical. For a list of the commands and their short forms, see Appendix B, Sun Cluster Object-Oriented Commands.
Before You Begin
Verify that the following prerequisites are met before starting the CCP:
-
Install the SUNWccon package on the administrative console.
-
Ensure that the PATH variable on the administrative console includes the Sun Cluster tools directories, /opt/SUNWcluster/bin and /usr/cluster/bin. You can specify an alternate location for the tools directory by setting the $CLUSTER_HOME environment variable.
-
Configure the clusters file, the serialports file, and the nsswitch.conf file if you are using a terminal concentrator. The files can be either /etc files or NIS or NIS+ databases. See the clusters(4) and serialports(4) man pages for more information.
-
If you have a Sun Enterprise 10000 server platform, log in to the System Service Processor (SSP).
-
From the administrative console, start the CCP launchpad.
phys-schost# ccp clustername
The CCP launchpad is displayed.
-
To start a remote session with the cluster, click the cconsole icon, crlogin icon, cssh icon, or ctelnet icon in the CCP launch pad.
How to Connect Securely to Cluster Consoles
Perform this procedure to establish secure shell connections to the consoles of the cluster nodes.
Before You Begin
Configure the clusters file, the serialports file, and the nsswitch.conf file if you are using a terminal concentrator. The files can be either /etc files or NIS or NIS+ databases.
Note –
In the serialports file, assign the port number to use for secure connection to each console-access device. The default port number for secure shell connection is 22.
See the clusters(4) and serialports(4) man pages for more information.
-
Become superuser on the administrative console.
-
Start the cconsole utility in secure mode.
# cconsole -s [-l username] [-p ssh-port]
- -s
-
Enables secure shell connection.
- -l username
-
Specifies the user name for the remote connections. If the -l option is not specified, the user name that launched the cconsole utility is used.
- -p ssh-port
-
Specifies the secure shell port number to use. If the -p option is not specified, the default port number 22 is used for the secure connections.
How to Access the Cluster Configuration Utilities
The clsetup utility enables you to interactively configure quorum, resource group, cluster transport, private hostname, device group, and new node options for the global cluster. The clzonecluster utility performs similar configuration tasks for a zone cluster. For more information, see the clsetup(1CL) and clzonecluster(1CL) man pages.
The phys-schost# prompt reflects a global-cluster prompt. Perform this procedure on a global cluster.
This procedure provides the long forms of the Sun Cluster commands. Most commands also have short forms. Except for the long and short forms of the command names, the commands are identical. For a list of the commands and their short forms, see Appendix B, Sun Cluster Object-Oriented Commands.
-
Become superuser on an active member node of a global cluster. Perform all steps of this procedure from a node of the global cluster.
-
Start the configuration utility.
phys-schost# clsetup
-
For a global cluster, start the utility with the clsetup command.
phys-schost# clsetup
The Main Menu is displayed.
-
For a zone cluster, start the utility with the clzonecluster command. The zone cluster in this example is sczone.
phys-schost# clzonecluster configure sczone
You can view the available actions in the utility with the following option:
clzc:sczone> ?
-
-
Choose your configuration from the menu. Follow the onscreen instructions to complete a task. For more detail, see the instructions in Configuring a Zone Cluster in Sun Cluster Software Installation Guide for Solaris OS.

View the configuration of a global cluster or zone cluster. Perform all steps of this procedure from a node of the global cluster.
% cluster show
Running the cluster show command from a global-cluster voting node shows detailed configuration information about the cluster and information for zone clusters, if you have configured them.
You can also use the clzonecluster show command to view the configuration information for just the zone cluster. Properties for a zone cluster include zone-cluster name, IP type, autoboot, and zone path. The show subcommand runs inside a zone cluster, and applies only to that particular zone cluster. Running the clzonecluster show command from a zone-cluster node retrieves status only about the objects visible to that specific zone cluster.
To display more information about the cluster command, use the verbose options. See the cluster(1CL) man page for details. See the clzonecluster(1CL) man page for more information about clzonecluster.

How to Validate a Basic Cluster Configuration
The cluster(1CL) command uses the check command to validate the basic configuration that is required for a global cluster to function properly. If no checks fail, cluster check returns to the shell prompt. If a check fails, cluster check produces reports in either the specified or the default output directory. If you run cluster check against more than one node, cluster check produces a report for each node and a report for multinode checks. You can also use the cluster list-checks command to display a list of all available cluster checks.
You can run the cluster check command in verbose mode with the -v flag to display progress information.
Note –
Run cluster check after performing an administration procedure that might result in changes to devices, volume management components, or the Sun Cluster configuration.
Running the clzonecluster(1CL) command at the global—cluster voting node runs a set of checks to validate the configuration that is required for a zone cluster to function properly. If all checks pass, clzonecluster verify returns to the shell prompt and you can safely install the zone cluster. If a check fails, clzonecluster verify reports on the global-cluster nodes where the verification failed. If you run clzonecluster verify against more than one node, a report is produced for each node and a report for multinode checks. The verify subcommand is not allowed inside a zone cluster.

How to Check the Global Mount Points
The cluster(1CL) command includes checks that examine the /etc/vfstab file for configuration errors with the cluster file system and its global mount points.
Note –
Run cluster check after making cluster configuration changes that have affected devices or volume management components.

How to View the Contents of Sun Cluster Command Logs
The /var/cluster/logs/commandlog ASCII text file contains records of selected Sun Cluster commands that are executed in a cluster. The logging of commands starts automatically when you set up the cluster and ends when you shut down the cluster. Commands are logged on all nodes that are up and booted in cluster mode.
Commands that are not logged in this file include those commands that display the configuration and current state of the cluster.
Commands that are logged in this file include those commands that configure and change the current state of the cluster:
-
claccess
-
cldevice
-
cldevicegroup
-
clinterconnect
-

-
scswitch
Records in the commandlog file can contain the following elements:
-
Date and timestamp
-
Name of the host from which the command was executed
-
Process ID of the command
-
Login name of the user who executed the command
-
Command that the user executed, including all options and operands
Note –Command options are quoted in the commandlog file so that you can readily identify them and copy, paste, and execute them in the shell.
-
Exit status of the executed command
Note –If a command aborts abnormally with unknown results, the Sun Cluster software does not show an exit status in the commandlog file.
By default, the commandlog file is regularly archived once a week. To change the archiving policies for the commandlog file, on each node in the cluster, use the crontab command. See the crontab(1) man page for more information.
Sun Cluster software maintains up to eight previously archived commandlog files on each cluster node at any given time. The commandlog file for the current week is named commandlog. The most recent complete week's file is named commandlog.0. The oldest complete week's file is named commandlog.7.
