Workaround

Do not leave the IMM web pages open on the System Status page for long periods of time.

After clearing any pop-up messages, if the web session still does not respond, the user should:

1. Terminate all current web sessions and start a new one.
2. If the user is unable to start a new web session, the user may try using telnet or SSH to access the IMM, and issue commands to query the health state and show the log entries.

Method 1

Use the Intelligent Platform Management Interface (IPMI) command.

ipmitool -H x.x.x.x -U userid -P password mc reset cold

where x.x.x.x is the Internet Protocol (IP) address of the IMM userid/password on a valid account on the IMM.

Method 2

Usie the F1 setup menu of the host.

Additional information

Until the targeted code becomes available, the Workaround provides information to:

• Prevent the symptom from occurring.
• Instruct the user on how to "wake up" or restart the IMM if the symptom occurs.
