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.

1. If you have a Sun Enterprise 10000 server platform, log in to the System Service Processor (SSP).

   1. Connect by using the netcon command.

   2. After the connection is made, type Shift~@ to unlock the console and gain write access.

2. From the administrative console, start the CCP launchpad.

   phys-schost# ccp clustername

   The CCP launchpad is displayed.

3. To start a remote session with the cluster, click the cconsole icon, crlogin icon, cssh icon, or ctelnet icon in the CCP launch pad.
