Administration Guide

Adding extension nodes and extension node adapters

You can add information for extension nodes and extension node adapters into the SDR by using either the SMIT or command line interface.

If the SP Switch has already been started, you must run Estart after you add an extension node and extension node adapter.

From SMIT

1. Access the Extension Node Database Information menu:

   ENTER

   smit enter_extdata

   • The Extension Node Database Information menu appears.

2. Add information to the SDR for extension nodes:

   SELECT

   Enter Extension Node Information

   • The Enter Extension Node Information menu appears.

   ENTER

   Values for the following extension node attributes:

   Administrative Hostname

   The fully qualified host name associated with the extension node's network interface on its system's administrative network. This name must resolve to an IP address. Required.

   SNMP Community Name

   The Simple Network Management Protocol (SNMP) community name for the authentication field in SNMP messages exchanged by the extension node's SNMP Agent and the SP SNMP Manager. This value can be 1 to 255 ASCII characters.

   Extension Node Identifier

   The string assigned to the extension node in its system's administrative environment. This string uniquely identifies the extension node to its system and can be 2 to 255 ASCII characters. Required. (See Specific implementations of extension nodes and extension node adapters for more information.)

   SNMP Agent Hostname

   Host name that resolves to an IP address that is the source or destination of SNMP packets exchanged with the control workstation via the SP administrative network. Required.

   Reconfigure the extension node?

   yes or no. yes notifies the SNMP Agent on the extension node that extension node information has been added or changed. This notification causes the SNMP Agent on the extension node to request configuration information from the SP SNMP Manager on the control workstation.

   Node Number

   The node number that corresponds to the valid unused switch port assigned to the extension node. Required. See IBM RS/6000 SP: Planning Volume 2, Control Workstation and Software Environment for information on switch node numbering.

   SELECT

   OK

3. Return to the Extension Node Database Information menu.
4. Add information to the SDR for extension node adapters:

   SELECT

   Enter Extension Node Adapter Information

   • The Enter Extension Node Adapter Information menu appears.

   ENTER

   Values for the following extension node adapter attributes:

   Network Address

   The IP network address for the extension node adapter.

   Network Netmask

   The network mask for IP addresses on the attached network on which the extension node adapter resides.

   Reconfigure the extension node?

   yes or no. yes notifies the SNMP Agent on the extension node that extension node information has been added or changed. This notification causes the SNMP Agent on the extension node to request configuration information from the SP SNMP Manager on the control workstation.

   Node Number

   The node number that corresponds to the valid unused switch port assigned to the extension node. Required. See IBM RS/6000 SP: Planning Volume 2, Control Workstation and Software Environment for information on switch node numbering.

   SELECT

   OK

From the command line

1. Use the endefnode command to add extension node information to the SDR.
2. Use the endefadapter command to add extension node adapter information to the SDR.

See the book PSSP: Command and Technical Reference for information on these commands.
