Item Description

GUI inter-

operability

restriction

The LifeKeeper for Linux client may only be used to administer LifeKeeper on

Linux servers. The LifeKeeper for Linux GUI willnotinteroperate with LifeKeeper

for Windows.

Starting and Stopping the GUI Server

To Start the LifeKeeper GUI Server

If the LifeKeeper GUI Server is not running, type the following command as root:

/opt/LifeKeeper/bin/lkGUIserver start

This command starts all LifeKeeper GUI Server daemon processes on the server being administered

if they are not currently running. A message similar to the following is displayed.

# Installing GUI Log

# LK GUI Server Startup at:

# Mon May 8 14:14:46 EDT 2006

# LifeKeeper GUI Server Startup completed at:

# Mon May 8 14:14:46 EDT 2006

Once the LifeKeeper GUI Server is started, all subsequent starts of LifeKeeper will automatically

start the LifeKeeper GUI Server processes.

Troubleshooting

The LifeKeeper GUI uses Ports 81 and 82 on each server for its administration web server and Java

remote object registry, respectively. If another application is using the same ports, the LifeKeeper

GUI will not function properly. These values may be changed by editing the following entries in the

LifeKeeper default file /etc/default/LifeKeeper.

GUI_WEB_PORT=81 GUI_RMI_PORT=82

Note: These port values are initialized in the GUI server at start time. If you alter them, you will

need to stop and restart the GUI server. These values must be the same across all clusters to

which you connect.

To Stop the LifeKeeper GUI Server

If the LifeKeeper GUI Server is running, type the following command as root:

/opt/LifeKeeper/bin/lkGUIserver stop
