Installation and Migration Guide

Replacing an I/O Planar card or an Ethernet adapter

Note:

|SDR adapter information includes the physical location code of the |adapter. If you are placing the replacement adapter in a different |location, you must run the spadaptrs command to update the physical |location code in the SDR. |

The I/O Planar card for nodes with an integrated Ethernet or the |SP Ethernet administrative LAN adapter for other nodes has a hardware address used to network boot the nodes. This procedure updates the SDR hardware Ethernet address.

• A ticket is required to perform some of the commands in this procedure. Run the k4init or dce_login command.
• Do these steps in the system partition in which you replace the card.

Step 1: Shut down the node

You can use Perspectives to power off the node.

If using:	Do this:
Perspectives	SELECT The Hardware Perspective icon SELECT The Nodes Pane The Nodes Pane receives focus. SELECT The node to power off PRESS Power Off icon SELECT The power off options PRESS Apply
cshutdown	Issue: cshutdown -G -N 48

Step 2: Replace the card

Your IBM Customer Engineer (CE) performs this step.

Step 3: Unallocate NIM resources

Unallocate NIM Resources on the boot/install server for the node you are replacing by issuing the unallnimres command. For example:

unallnimres -l 33

Step 4: Delete the NIM client

Delete the NIM client on the boot/install server for the node you are replacing by issuing the delnimclient command from the control workstation. For example, to delete node 3 from the boot/install server, issue:

delnimclient -l 3

Step 5: Obtain the new hardware Ethernet address

If you have Ethernet information for the node being replaced in /etc/bootptab.info, be sure to remove the old address.

Use the sphrdwrad command to get the new hardware Ethernet address.

Step 6: Re-create the NIM client definition

To re-create the NIM client definition, issue the mknimclient command. For example, to re-create the NIM client for node number 3, issue:

mknimclient --l 3
