Sun Cluster 3.0-3.1 Hardware Administration Manual for Solaris OS

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 PatchPro. PatchPro is available online to Sun service providers and to customers with service contracts at the PatchPro site:

GigaSwift Ethernet Driver and Jumbo Frames

If you are using jumbo frames, you must edit the ce.conf file to configure them, as explained in the Sun GigaSwift documentation.

The driver documentation instructs you to grep certain entries from the /etc/path_to_inst file to determine your entries for the ce.conf file. If you are using an operating system earlier than the Solaris 10 OS, the OS modifies the entries on Sun Cluster nodes, adding a node-identifier prefix to them. For example, an entry modified for a Sun Cluster node resembles the following:

# grep ce /etc/path_to_inst 
"/node@1/pci@8,600000/network@1" 0 "ce"

When editing the ce.conf file, remove the /node@nodeID identifier prefix from the entries that you put into the driver configuration file. For the example above, the entry to put into the configuration file is:

"/pci@8,600000/network@1" 0 "ce"
