Install a New Processor Module
This topic describes how to increase the number of processor modules in your
server from one processor module to two. For instructions on replacing a processor
module that has failed, see Replacing a Faulty Processor Module.
- Determine if you have logical domains (LDoms) configured on the single processor module that
you currently have installed in your server.
- If you do not have LDoms configured on the single processor in your
server, go to Step 3.
- If you have LDoms configured on the single processor module in your server,
follow these steps to preserve the original LDoms configuration before you add the second
- For each of the LDoms created, save the LDom constraints configured as an
# ldm list-constraints -x ldom >ldom.xml
# ldm list-constraints -x ldg1 >lgd1.xml
- Perform this step individually for all LDoms present in your server, saving the
constraints for each LDom as a separate xml file.
For example, save the primary domain as primary.xml, the first guest domain as
ldg1.xml, and so on.
- Power off the server.
See Removing Power From the Server.
- Remove the filler panel from the empty processor module slot, if one is
- Insert the new processor module into the empty processor module slot in the
- Bring the levers together toward the center of the module and press them
firmly against the module to fully seat the module back into the server.
The levers should click into place when the module is fully seated in
- Power on the server.
See Returning the Server to Operation.
- Determine if you need to restore the OVM configuration information.
- If you had not configured logical domains on the single processor module before installing
the second one, you do not have to restore the OVM configuration information.
Go to Step 8.
- If you had configured logical domains on the single processor module before installing
the second one, follow these procedures to restore the OVM configuration information that you
saved earlier in this process:
- Change the server's method of booting to its factory default setting:
-> set /HOST/bootmode config=factory-default
- Boot the server again using the start /SYS command at the service processor prompt:
-> start /SYS
- List all the guest domains that you currently have configured:
# ldm ls
- Stop all the guest domains using the -a option:
# ldm stop-domain -a
- Unbind each of the guest domains:
# ldm unbind-domain ldom
- Destroy each of the guest domains:
# ldm destroy ldom
- Restore the primary domain configuration:
# ldm init-system -i primary.xml
- Restore each guest domain configuration.
For each guest domain, enter the following commands to add, bind, and then
restart each domain:
# ldm add-domain -i ldg1.xml
# ldm bind ldg1
# ldm start ldg1
