Installation and Migration Guide
- Note:
- |If the adapter was originally specified using a physical location
|code and 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.
|
To change an Ethernet cable type, perform the following steps. As
with many PSSP commands, you must have the appropriate authority or
credentials to use them. See Step 24: Obtain credentials.
You can use Perspectives to power off the nodes.
| If using:
| Do this:
|
| Perspectives
| From the Hardware Perspective menu bar
- SELECT
- The Hardware Perspective icon
- SELECT
- The Nodes Pane
- The Nodes Pane receives focus.
- SELECT
- The nodes to power off
- PRESS
- The Power Off icon
- SELECT
- The Power Off options
- PRESS
- Apply

| cshutdown
| Issue:
cshutdown -G -N 48

Your IBM Customer Engineer (CE) performs this step.
If any resources are allocated to the affected nodes, you must deallocate
the NIM resources. For example, to deallocate resources for nodes 1, 2,
and 3 from the boot/install server, issue:
unallnimres -l 1,2,3
Delete the NIM clients on the boot/install server for the nodes you are
replacing by issuing the delnimclient command from the control
workstation. For example, to delete nodes 1, 2, and 3 from the
boot/install server, issue:
delnimclient -l 1,2,3
To change the Ethernet cable type entry in the SDR, perform the following
steps.
- Note:
- You must reenter data that is not changing. If you do not know these
values, you can obtain them by issuing the following two commands.
For the default route, issue:
splstdata -n
For the netmask, issue:
splstdata -a
| If using:
| Do this:
|
| SMIT
|
- TYPE
- smit enter_data
- SELECT
- Node Database Information
- SELECT
- SP Ethernet Information
- ENTER
- Start frame, start slot, and node count
OR
Node group
OR
Node list
AND
Starting node's SP Ethernet administrative LAN adapter host
name or IP address (for models other than the IBM  pSeries 690,
you must specify the en0 adapter name), netmask, default route host name or IP
address.
- SELECT
- Ethernet Adapter Type and type F4 to generate the list
- CHOOSE
- The appropriate type from the list
- SELECT
- Ok

| spadaptrs
| This example configures an SP Ethernet administrataive LAN adapter
network of 16 nodes with IP addresses ranging from
129.33.32.1 to 129.33.32.16, a
netmask of 255.255.255.192, and a default route of
129.33.32.200. The adapter is a twisted pair
10/100 Ethernet adapter using auto-negotiate for the communication transfer
and rate.
spadaptrs -e 129.33.32.200 -t tp -d auto -f auto 1 1 16 en0 129.33.32.1
255.255.255.192
|
- Note:
- If you are replacing your Ethernet adapter, you need to acquire the new
hardware Ethernet address using the sphrdwrad command.
Use the spbootins command to set the nodes to customize and run
the setup_server command. For example, to set nodes 1, 2, and
3 to customize, issue:
spbootins -r customize -s yes -l 1,2,3
- Note:
- In order to run the spbootins -s yes command, you must have SDR
write authority and be authorized to perform an rsh to the target
nodes. Therefore, your user ID must be in the appropriate authorization
file (.k5login, .klogin, or
.rhosts) on the target nodes.
Power on the nodes. This causes the customization to take place that
updates the adapters on the nodes.
