Complete the following steps to configure the global SOL settings for the BladeCenter® unit:
- Start the BladeCenter management-module Web interface (see Starting the BladeCenter management-module Web interface).
- In the navigation pane, click Blade Tasks → Serial Over LAN. In the management-module information page that opens make sure that the settings match the following default values or are set to the values that are required by your network configuration. Unless otherwise noted, the default management-module SOL settings provide the best overall SOL performance. (For advanced management modules, click the Serial Over LAN configuration link to access the SOL settings.)
The following illustration shows SOL settings for management modules other than an advanced management module.
The following illustration shows SOL settings for an advanced management module.
The SOL settings and recommended values are:
-
Serial Over Lan: Enabled
Use this field to enable or disable SOL globally for the BladeCenter unit. If SOL is enabled globally and if SOL is enabled for a blade server, an SOL session can be established with that blade server. If SOL is disabled globally, no SOL sessions can be established with any blade servers in the BladeCenter unit.
-
SOL VLAN ID (management modules other than the advanced
management module)
- For all switch modules other than the Cisco Systems Intelligent Gigabit Ethernet Switch Module for the IBM® BladeCenter, the SOL VLAN ID must be set to 4095 (default value).
- For the Cisco Systems Intelligent Gigabit Ethernet Switch Module for the IBM BladeCenter the
SOL VLAN ID is set as follows:
- For Cisco IOS releases earlier than 12.1(22)EA6a, the SOL VLAN ID can be set to any value between 3 and 1001: it cannot be set to the default value of 4095.
- For Cisco IOS release 12.1(22)EA6a and later, the SOL VLAN ID is set to
a default value of 4095. If desired, you can still set your own defined VLAN
ID. Note: If your blade server has a Broadcom Ethernet controller and you want to use an SOL VLAN ID of 4095 for the Cisco Systems Intelligent Gigabit Ethernet Switch Module, upgrade to the latest versions of blade server Broadcom Ethernet Controller firmware (minimum level supported is 1.20.14).
If you set the SOL VLAN ID to a custom value, write it down for later use during the configuration process.
-
BSMP IP Address Range: x.x.x.x
(management modules
other than the advanced management module)
This is a mandatory field where x.x.x.x is the base IP address for blade servers that is used for internal communication inside the BladeCenter unit. 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 that is set in this field. For example, if the value that you enter is 10.1.1.1, the blade server in blade bay 1 will have IP address 10.1.1.1, the blade server in blade bay 2 will have IP address 10.1.1.2, and so on.
- Accumulate timeout: 25 (default value is 5 for management modules other than the advanced management module and 150 for the advanced management module)
- Send threshold: 250
- Retry count: 3
- Retry interval: 2500 (default value is 250)
Do not attempt to enable or disable SOL on any of the blade servers that are listed in the Serial Over LAN Status section.
