Generate IP Mapping Information for DNS

Language:

When you finish entering the necessary information into the Initial Configuration tool, click the appropriate button at the bottom of the screen.
- Review — Begins the review process to verify that all the information entered in the tool is valid. Go to Step 2.
- Reset — Clears all the fields in the tool.
- Exit — Exits out of the tool.

Verify the summary information.
A screen appears with a summary of the information that you entered, including the IP address and host name mapping for the management and client access networks.
Enter the necessary information shown in the IP Hostname Mapping pane into DNS.
The IP address information that you provided in the IP Allocation pane is displayed.

The first 12 IP addresses, which have hostnames provided automatically through the tool, are for the management network (2 IP addresses) and client access network (10 IP addresses) for the system-level components. Enter all 12 of these system-level IP address and host names into DNS before proceeding. These 12 IP addresses are automatically used for these system-level components:
- On the management network, Oracle ILOM for the service processors (SPs) in compute nodes 1 and 2 (two IP addresses and host names)
- On the client access network:
  - Host names for compute nodes 1 and 2 (two IP addresses and host names)
  - Host names for kernel zones on compute nodes 1 and 2 (two IP addresses and host names)
  - Oracle RAC VIP for kernel zones on compute nodes 1 and 2 (two IP addresses and host names)
  - NFS VIP (one IP address and host name)
  - SCAN IP addresses for system-level Oracle RAC (three IP addresses and host names)
The remaining unassigned IP addresses on the client access network will be used later on when you create virtual machines.
Determine if you are running the Initial Configuration tool on a system that is on the same network where the MiniCluster will be installed.
The next step verifies that the IP Hostname Mapping information was entered into DNS correctly and assumes that you are connected to the same network where the MiniCluster will be installed.
- If you are running the Initial Configuration tool on a system that is on the same network where the MiniCluster will be installed, go to Step 5.
- If you are not on the same network where the MiniCluster will be installed, you can continue with these instructions at this time without verifying that the information was entered into DNS correctly. However, you must return to these instructions later on, when you are able to run the Initial Configuration tool on the same network that the MiniCluster will be installed on, and verify the information prior to setting up the MiniCluster.
  
  If you are postponing the DNS check until a later date, continue to Step 7 to generate the necessary configuration files, including the userinputs.txt file, and continue with the remaining preliminary configuration tasks. At a later date, when you are on the same network where the MiniCluster will be installed (but prior to receiving your MiniCluster), click the Import Configuration File button described in Provide General Configuration Information to import the userinputs.txt that you generated, then repeat these instructions from this point to use the Check IP button to verify the DNS information before setting up your MiniCluster.

After you have entered the system-level IP addresses and host names into DNS, click the Check IP button.
The tool checks DNS to verify you entered the information into DNS properly where the status should be matched or available.

A progress bar appears at the bottom of the screen, providing status for this check.
Verify that the system-level IP addresses and host names were entered into DNS properly.
Note - The unreachable part in the Status field is expected, because you are running this IP check before you set up your MiniCluster.

Note - Any result other than matched or unreachable indicates that there is a problem.
- If you see matched/unreachable in the Status field for all of the system-level fields, then you entered the system-level IP addresses and host names into DNS properly. Go to Step 7.
- If you see unmatched/unreachable in the Status field for any of the system-level fields, then there was an issue with the DNS entry. Either verify the entries in DNS, or click the Back button to go to the previous screen to correct the IP addresses. Then repeat this step until all the system-level IP addresses and host names are shown as matched/unreachable in the Status field.
  
  Tip - You can also change the entries in the IP Address and MiniCluster Hostname columns (the first and second columns) by double-clicking in any field in those columns. Change the information in either of those columns to correspond with the entries in the DNS Hostnames column, then click the Check IP button again.
Do not proceed with these procedures until you see matched/unreachable in the Status field for all of the system-level fields.

Click the appropriate button in the summary screen.
Note - If you ran the Initial Configuration tool previously, you might already have two configuration files generated from that earlier run. Clicking Save in this step will overwrite those previously-generated configuration files, so if you want to save those earlier files, rename them or move them to a different location before clicking Save here.
- Save — Generates the necessary configuration files and saves them in the same directory as the Initial Configuration tool. Go to Step 8.
- Back — Takes you back to the tool screen.
- Exit — Exits out of the tool.

Verify that the configuration files were generated correctly.

The tool generates the userinputs.txt and omcips.txt files, which you need to complete the initial configuration procedure. The files are copied into the same directory where you ran the tool. Note this location for future use.

Note - Do not manually edit the userinputs.txt or omcips.txt files. These files can only contain information that was generated through the Initial Configuration tool. You can rename the names of the files, if necessary, but you should retain the userinputs and omcips aspects of the file names to distinguish the file types (for example, mc2-userinputs.txt and mc2-omcips.txt).
Click the appropriate button.
- Start Over — Runs the Initial Configuration tool again.
- Finish — Closes the Initial Configuration tool.
