Installing and Maintaining Public Network Hardware
This chapter describes the procedures about how to install and maintain public network hardware.
This chapter contains information about how to maintain public network hardware. This chapter contains the following procedures.
For conceptual information on cluster interconnects and public network interfaces, see your Sun Cluster concepts documentation.
For information on how to administer public network interfaces, see your Sun Cluster system administration documentation
Installing Public Network Hardware
This section covers installing cluster hardware during an initial cluster installation, before Sun Cluster software is installed.
Physically installing public network adapters to a node in a cluster is no different from adding public network adapters in a noncluster environment.
For the procedure about how to add public network adapters, see the documentation that shipped with your nodes and public network adapters.
Where to Go From Here
Install the cluster software and configure the public network hardware after you have installed all other hardware. To review the task map about how to install cluster hardware, see Installing Sun Cluster Hardware.
Maintaining Public Network Hardware in a Running Cluster
The following table lists procedures about how to maintain cluster interconnect and public network hardware. The interconnect maintenance procedures in this section are for both Ethernet-based and PCI-SCI interconnects.

How to Add Public Network Adapters
Physically adding public network adapters to a node in a cluster is no different from adding public network adapters in a noncluster environment.
For the procedure about how to add public network adapters, see the hardware documentation that shipped with your node and public network adapters.
Where to Go From Here
To add a new public network adapter to an IP Network Multipathing group, see the IP Network Multipathing Administration Guide.
How to Replace Public Network Adapters
For cluster-specific commands and guidelines about how to replac public network adapters, see your Sun Cluster system administration documentation.
For procedures about how to administer public network connections, see the IP Network Multipathing Administration Guide.
For the procedure about remove public network adapters, see the hardware documentation that shipped with your node and public network adapters.
Where to Go From Here
To add the new public network adapter to a IP Network Multipathing group, see your Sun Cluster system administration documentation.
How to Remove Public Network Adapters
For cluster-specific commands and guidelines about how to remove public network adapters, see your Sun Cluster system administration documentation.
For procedures about how to administer public network connections, see the IP Network Multipathing Administration Guide.
For the procedure about how to remove public network adapters, see the hardware documentation that shipped with your node and public network adapters.
Sun Gigabit Ethernet Adapter Considerations
Some Gigabit Ethernet switches require some device parameter values to be set differently than the defaults. Chapter 3 of the Sun Gigabit Ethernet/P 2.0 Adapter Installation and User's Guide describes the procedure about how to change device parameters. The procedure that you use on nodes that are running Sun Cluster software varies slightly from the procedure that is described in the guide. In particular, the difference is in how you derive parent names for use in the ge.conf file from the /etc/path_to_inst file.
Chapter 3 of the Sun Gigabit Ethernet/P 2.0 Adapter Installation and User's Guide describes the procedure on how to change ge device parameter values. This change occurs through entries in the /kernel/drv/ge.conf file. The procedure to derive the parent name from the /etc/path_to_inst listing, which is be used in ge.conf entries, appears in Setting Driver Parameters Using a ge.conf File. For example, from the following /etc/path_to_inst line, you can derive the parent name for ge2 to be /pci@4,4000.
"/pci@4,4000/network@4" 2 "ge" |
On Sun Cluster nodes, a /node@nodeid prefix appears in the /etc/path_to_inst line. Do not consider the /node@nodeid prefix when you derive the parent name. For example, on a cluster node, an equivalent /etc/path_to_inst entry would be the following:
"/node@1/pci@4,4000/network@4" 2 "ge" |
The parent name for ge2, to be used in the ge.conf file is still /pci@4,4000 in this instance.
ce Sun Ethernet Driver Considerations
The Sun Cluster software supports the ce Sun Ethernet driver for cluster interconnect and public network applications. Consult your Sun sales representative for details on which network interface products are supported. These network interfaces can only be used as new interconnects and public network interfaces. As such, you cannot upgrade from another type of adapter card to those network interfaces by using the ce Sun Ethernet driver.
When you use the ce Sun Ethernet driver for public network connections, add the following line to your /etc/system file.
set ce:ce_reclaim_pending=1 |
Apply any required patches, and then reboot the system. See the Sun Cluster system administration documentation for instructions on rebooting a cluster node.
The ce driver version must be at least 1.115. To determine the ce driver version, run the following command.
# modinfo | grep CE |
Note - For the current list of patches that are required for the ce Sun Ethernet driver, refer to SunSolve. SunSolve is available online to Sun service providers and to customers with SunSolve service contracts at the SunSolve site: http://sunsolve.sun.com.
