8.3 Configuring SOL for use with the Nortel GbESM
The latest updates for the following components should be obtained prior to setting up SOL:
BladeCenter Management Module
Blade Server BIOS
Blade Server Diagnostics
Blade Server system integrated system management processor (ISMP)
Blade Server Broadcom Ethernet firmware
Blade Server Broadcom Ethernet device driver
Nortel Networks L2/3 GbESM
As long as the SOL VLAN ID value in the Management Module Web interface is set to 4095,
there are no other specific configuration steps for the Nortel Networks L2/3 GbESM, because
the Nortel Networks L2/3 GbESM reserves VLAN 4095 for SOL. All other configuration steps
involve either the Management Module or the blade server. To properly set up and configure
both the Management Module or blade server, refer to the following Web site:
http://www-307.ibm.com/pc/support/site.wss/document.do?Indocid=MIGR-54666
Also of note here, you do not need to modify the BSMP IP Address Range field. This value is
the base IP address for blade servers in the BladeCenter (the last octet is incremented for
each blade server in the chassis). The IP address that SOL uses to communicate with the
blade system management processor (BSMP) of each blade server is based on the IP
address set in this field.
8.4 SOL use during Nortel Networks L2/3 GbESM experiments
SOL was enabled on an HS40 blade server during the experiments that we used for this
paper. The blade server was set up according to the following document:
http://www-307.ibm.com/pc/support/site.wss/document.do?Indocid=MIGR-54666
The default timeout value of telnet was changed in the Management Module. This allowed for
the SOL session to stay up continually for monitoring the blade server. This value cannot be
set using the Management Module Web interface. To reset the timeout of telnet for the
Management Module, do the following:
1. Telnet to the Management Module and login with USERID and PASSW0RD.
2. At the <system> prompt type
env -T system:mm[1]
.
3. Type
telnetcfg
to display the current setting.
4. To change the value to the desired number of seconds (4000 for example, which is just
over an hour), type
telnetcfg -t 4000
.
5. Type
env
to return to the <system> prompt.
Important: It is not recommended that you use your production subnet for the BSMP IP
Address Range field. These addresses are only used by the Management Module and the
blade server’s ISMP for SOL translation. You cannot telnet into them or use them any
other way. The Management Module cannot be bypassed when trying to open a SOL
session to a blade server.
