Having a fully virtualized server environment is great, but with the constant push towards public services, there has been an increase in DMZ servers for many companies.

When creating an LPAR, follow the steps here for help, and add these simple tweaks to make your life easier when building an LPAR in the DMZ

1. Before creating the LPAR, ensure that you have all of the details and netwo...

Checklist:

• IP address(es)
• LUN number(s)
• Host name
• Processing unit requirements of the new LPAR
• Memory requirements of the new LPAR
• Dedicate I/O requirements of the new LPAR
• Shared processor pool in which the new LPAR will be put Virtual I/O requirements of the new LPAR

1. Login as hscroot

2. “Systems Management”->“Servers” ->select server ->“Configuration”->”Create Logical Partition”->”AIX or Linux”
3. Do not change the system assigned partition ID. Input hostname as partition name -> click “Next”
4. Use hostname as profile name. DO NOT select “Use all the resources in the system” unless this will be the only LPAR on the system. Click “Next” to continue.
