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
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.
Information about the ability to detach and force resource groups offline; see “Take a Resource Group Offline” in Chapter 7.
