How to Change the Operations Console LAN IP Address

Troubleshooting


Problem

This document describes how to change the IP address used for operations console LAN.

Resolving The Problem

This document describes how to change the IP address used for operations console LAN connection. It assumes the console type is already set to LAN (3).

Preparation:

aObtain the new network information:

IP address: ________________________________________________________

Subnet mask: ______________________________________________________

Gateway: _________________________________________________________

Hostname/Connection name: _________________________________________

Note: The name used for the connection does not have to be registered in the DNS; however, it cannot be the same as host name already registered in the DNS. A good practice is to use the partition's (as400) host name with "con" (for console) appended. For example, Dev400Con
bPing the new IP address.
Verify there is no reply.
If a reply is received, another device is using the IP address. Either that device must be disconnected or another IP address obtained.
cPing the console name.
Ping the name you plan to use for the new operations console connection.
Verify that it returns an error indicating host is not found or, if it is registered in the DNS, verify that it returns the same IP address you plan to assign. If it returns an incorrect IP address, you must either correct the DNS entry or obtain a new name.
d(Optional) Record the existing connection Device ID.
If the existing operations console connection is still available, note the device ID being used.
- V5R4 only: If console connection status is "connected", disconnect the console connection.
- Right click the connection, then click Properties.
- Note the device ID being used. It is the unlabeled field on the line after Encryption.

Operations console properties - general tab.



Note: For the procedure below, IBM support recommends using a normal (non-console) 5250 emulation session to make the change if possible. This allows easier recovery if a configuration error is made because the IP interface is not affected. If the console session is used, follow the steps carefully to ensure a successful change.

1. Reset the Device ID
Note: Skip this step and continue to step 2 if the OS is IBM i 6.1, 7.1 (or later) - auto create device ids is enabled by default at those levels.
aAccess service tools.
Type STRSST, and press Enter.
Log on with QSECOFR service tools ID/password.
bOption 8. Work with service tools user IDs and Devices.
cOption 2: Service tools device IDs.
If you receive an error such as The user can not perform the option selected, it implies the option to Work with device IDs from SST has not been enabled. The operation must be done from the console using DST or by using the front control panel.
    For information on how to reset the default device ID QCONSOLE using the control panel, refer to the following URL: http://publib.boulder.ibm.com/infocenter/powersys/v3r1m5/index.jsp?topic=/iphbx_p5/recoverserverqconsole.htm

    To reset a device ID using DST:
      - Access dedicated service tools. Refer to Rochester Support Center knowledgebase document New, New System Setup - Beyond the Basic Console Connection, section "To access Dedicated Service Tools on the console". To link to document New immediately, click here Database 'DCF Technotes (IBM i)', View 'Products', Document 'New System Setup - Beyond the Basic Console Connection'.

      - Select 5. Work with DST environment, then select 5. Service tools device IDs.
      Tip: You can enable the ability to work with device IDs in SST from DST. Refer to Rochester Support Center knowledgebase document New System Setup - Beyond the Basic Console Connection, section "Enable ability to Work with Service Tools Device IDs in SST". To link to document New immediately, click here Database 'DCF Technotes (IBM i)', View 'Products', Document 'New System Setup - Beyond the Basic Console Connection'
dReset the device ID
Note: The reset can be done on a device ID even while it is in use.
- Locate the device ID to reset. This is the existing device (see preparation above) or the default device of QCONSOLE.
- Type 2 (reset password), then press Enter.

Tihs is the device ID screen.

- When prompted, press Enter again to confirm the reset.

Note: Do not disconnect, then reconnect the console prior to Step 3c or this will set the device ID causing a device ID mismatch error.


2. Change the LAN adapter address.
aAccess SST or DST
SST: 8. Work with service tools user IDs and Devices
DST: 5. Work with DST environment
2. System devices
bSST: 4. Configure service tools LAN adapter
DST: 7. Configure service tools LAN adapter
cEnter the new TCP configuration data:

This is the configuration screen.
dPress F7 (Store) to save your changes.
ePress F17 (F17=Deactivate followed by activate) to apply the changes.
Note: When you press F17, the console connection will drop. The server will restart the console LAN adapter using the new configuration. It should be active within a few minutes (in other words, respond to ping or an operations console connection).
3. Delete and re-create the operations console connection.
aDisconnect the existing operations console connection.
bDelete the existing operations console connection.
Right mouse click the existing connection, then click Delete.
cCreate a new connection
Click Connection, New Connection.
Enter the information as prompted by the wizard. Use the same network settings that were entered in Step 2 and the same device ID used/reset previously (in other words, QCONSOLE).
dConnect the new console connection.
- Right mouse click the new connection, then click Connect.
- When prompted, enter the Access password (if requested), Service Tools user ID and password (11111111/11111111). Click OK.
4. (Optional) Enable console takeover and recovery

If console LAN adapter cabling changed so that the LAN console connection now goes through a switch, IBM recommends enabling console takeover and recovery. Further information on takeover and recovery can be found in the Information Center at the following URL: http://publib.boulder.ibm.com/infocenter/iseries/v7r1m0/topic/rzajr/rzajrconsoletakeoverandrecover.htm

To enable takeover and recovery:
aAccess service tools.
Type STRSST, and press Enter.
Log on with QSECOFR service tools ID/password.
bSelect Option 8. Work with service tools user IDs and Devices.
cSelect Option 3. Select console
dSet Allow console recovery and console can be taken over by another console to 1=Yes. Press Enter, press Enter again:
