Chapter 6. Troubleshooting SOL

This section contains some troubleshooting hints and tips to assist you in solving

problems that you might be experiencing with Serial over LAN operation. Go to

http://www.ibm.com/systems/support/ for the latest information about solving

problems with SOL. Information in this section relates to the following topics:

Note:

If you are using management channel auto discovery (MCAD), replace

references to I/O-module bay 1 in the following procedures with the I/O module

bay number that is actually being used (see the

BladeCenter Advanced Management

Module User's Guide

for additional information about MCAD).

“Management module indicates that blade server does not support SOL”

v

“Blade server shows SOL status of Not Ready” on page 46

v

“SOL session opens and drops” on page 47

Management module indicates that blade server does not support SOL

If the management module SOL configuration page indicates that a blade server

does not support SOL, check the following items:

v

Make sure that blade server type that you are using supports SOL. For example,

the Type 8678 blade server does not support SOL and this is a normal message

for this blade server type.

v

The management module has not completed its communication sequence with

each of the blade servers in the BladeCenter unit. This condition commonly

occurs immediately after power has been applied to the BladeCenter unit or

after an management module reset. Allow 5 minutes after power application or a

management module reset to make sure that all blade servers have been

scanned.

v

Turn off the blade server, remove it from the BladeCenter unit, reinstall it, and

turn it back on.

v

Move the blade server to a different blade bay.

v

Update the blade server service processor firmware (BMC or ISMP firmware).

Latest firmware is available from http://www.ibm.com/systems/support/.

Install the update by following the instructions that come with the update. See

the

Management Module User's Guide

for additional information.

v

Try a different management module. If the BladeCenter unit contains a standby

management module, switch control to it and wait 5 minutes for the

management module to fully establish communications with all blade servers.

v

Update the management module firmware. Latest firmware is available from

http://www.ibm.com/systems/support/. Install the update by following the

instructions that come with the update. See the

Management Module User's Guide

for additional information.

v

There might be a problem with the blade server system board.
