## New Features in This Guide

This revision contains the following new information:

- The graphical user interface (GUI) has been improved. The separate cluster view (the `fsdetail` command) and task manager (the `fstask` command) have been streamlined into one window, the FailSafe Manager. Both the `fstask` and `fsdetail` commands are kept for historical purposes; this document refers to just `fstask` for simplicity.

  The new GUI provides the following features:

  - Access to tasks through the menu bar or by clicking the right mouse button within the tree view

  - Faster status updates

  - Access to the `salog(4)` file, which shows every command run from the GUI

  - A Find textfield helps you find components within the displayed tree-view

  See “FailSafe Manager GUI” in Chapter 4.

- Optional logging of ESP events for FailSafe; see “Embedded Support Partner (ESP) Logging of FailSafe Events” in Chapter 7.

- CXFS plug-in information and expanded information about coexecution; see “Coexecution of CXFS and IRIS FailSafe” in Chapter 2.

- Clarification about the use of NFS with UDP (recommended) and TCP (not recommended); see “Software Overview” in Chapter 1.

- List of included and optional plug-ins; see “Layers” in Chapter 1.

- Use of descriptive variable names in `cmgr` descriptions and reorganization of GUI instructions to match GUI screens; see Chapter 5, “Configuration”.

- More information about hostname resolution; see “Hostname Resolution: /etc/sys_id, /etc/hosts, /etc/nsswitch.conf” in Chapter 3.

- Information about testing the system during initial configuration. See “Test the System” in Chapter 3.
