Replacing a CPU Board

For information about how to replace a CPU board on a node, see the following sections:

Replacing a Board on a Node

To replace the board on a the vice-master node, a diskless node, or a dataless node, perform the following procedure. If the node is a diskless node that is using the DHCP client ID boot policy, perform the procedure in Replacing a Board on a Diskless Node With the DHCP Client ID Boot Policy.

ProcedureTo Replace a Board on a Node

  1. Verify that the new board is of the same type as the old board.

  2. Replace the board using information in the hardware documentation on http://www.sun.com/products-n-solutions/hardware/docs/.

  3. Log in to the new node.

  4. Get the ok prompt.

  5. Configure the OpenBoot™ PROM (OBP) parameters.

    The following examples show the OBP parameters for a Netra T1 diskless node and a Netra T1 master-eligible node.

    • A Netra T1 diskless node has these OBP parameters:

      ok> setenv local-mac-address? true
      ok> setenv auto-boot? true
      ok> setenv diag-switch? false
      ok> setenv boot-device net:dhcp,,,,,5 net2:dhcp,,,,,5

    • A Netra T1 master-eligible node or dataless node has these OBP parameters:

      ok> setenv local-mac-address? true
      ok> setenv auto-boot? true
      ok> setenv diag-switch? false
      ok> setenv boot-device disk net

  6. Reboot the node:

    ok> boot

  7. Log into the node as superuser.

  8. Verify that the node is configured correctly:

    # nhadm check

Replacing a Board on a Diskless Node With the DHCP Client ID Boot Policy

To replace the board on a diskless node that is using the DHCP client ID boot policy, perform the following procedure.

ProcedureTo Replace a Board on Diskless Nodes With the DHCP Client ID Boot Policy

This procedure is an example of how to replace a board on a diskless node in a Netra CT 410, Netra CT 810 configuration. For information specific to your hardware configuration, see the hardware documentation.

  1. Retrieve the client identifier in ASCII format, for the diskless node.

    If the node is running, you can retrieve the client identifier for the diskless node, as follows.

    1. Log in to the diskless node as superuser.

    2. Get the ok prompt.

    3. Display the client identifier of the diskless node.

      ok> printenv dhcp-clientid
      client-id-name

      In this example the client identifier is the string client-id-name.

  2. Perform Step 1 to Step 5 of Replacing a Board on a Node.

  3. Define the client identifier for the new diskless node.

    ok> setenv dhcp-clientid client-id-name

  4. Perform Step 6 to Step 8 of Replacing a Board on a Node.
