This rewrite of the IRIX GSN Administrator's Guide supports the 2.1 release of the SGI Gigabyte System Network (GSN) product.

This rewrite focuses on the new version of HARP and the new HARP daemon, harpd, which performs many functions previously performed in the kernel. Substantial changes have been made to the gsnarp function. GSN startup now uses the harpd.options file instead of the gsnarp.options file. Included in this rewrite are error messages from the harpd command and from the HARP driver.
