Bug ID 4371236

Problem Summary: Some ge switches require some of the ge device parameters to be set to values other than the default values. Chapter 3 of the Sun GigabitEthernet/P 2.0 Adapter Installation and User's Guide describes the procedure to change ge device parameters. The procedure to be used on nodes running Sun Cluster 3.0 software varies slightly from that described in the guide. In particular, the difference is in how the device path names in the /etc/path_to_inst file are used to derive parent names for use in the ge.conf file.

Workaround: Chapter 3 of the Sun GigabitEthernet/P 2.0 Adapter Installation and User's Guide describes the procedure to change ge device parameter values through entries in the /kernel/drv/ge.conf file. The procedure to determine the parent name from the /etc/path_to_inst listing (to be used in ge.conf entries) appears on page 24, "Setting Driver Parameters Using a ge.conf File." For example, from the following /etc/path_to_inst line, you can determine the parent name for ge2 to be /pci@4,4000.

"/pci@4,4000/network@4" 2 "ge"

On cluster nodes, you must delete the /node@nodeid prefix in the device paths in /etc/path_to_inst prior to using that prefix as a parent name. For example, on a cluster node, an equivalent /etc/path_to_inst entry could have been the following entry.

"/node@1/pci@4,4000/network@4" 2 "ge"

The parent name for ge2 to use in ge.conf is still /pci@4,4000.
