How do I configure/Change IP address on AIX System

To configure/change the IP address you must be logged as a root user.

Gather your network configuration information:
– IP address
– Host name
– Domain Name
– Subnetmask (optional)
– Name server (optional)
– Gateway address (optional)

On the command line,type the command:

smitty mktcpip

When prompted chose the Network interface you plan to use.

How do I set the IP address on my DIGI LAN server?

NOTE: these steps must be performed on the same LAN as the device.

  • Record the MAC address of the Digi device (located on the label side (bottom) of the unit)
  • Manually update the workstation’s ARP table using the Digi device’s MAC using one of the commands below, substituting the new Digi’s IP address and MAC address:
arp -s 00-00-9d-22-23-60
arp -s 00009d222360
  • Ping the Digi device using the IP address just assigned:
  • When the Digi begins responding to pings, enter the IP into a web browser and login (user/pass root/dbps) to set the default gateway and subnet mask
  • Add to the digi device IP address to the /etc/hosts file
    vi /etc/hosts digi
  • Notify Eclipse that the Digi is online by updating your service request online with the Digi IP address
  • Eclipse will verify connectivity to the Dig and continue the VSIFAX configuration process

How do I create a mksysb tape backup on AIX?

These instructions are for AIX 7.1. If you are on AIX 6.1, the steps will be similar. If you are on a previous version of AIX, you should upgrade as soon as possible.

Use Eterm, the local console or HMC to log into the server as root.

At the root command prompt (#), run:

smit mksysb

At the “Back Up This System” screen, press ESC-4 or F4 to change the highlighted fields:

* Backup DEVICE or FILE                              [/dev/rmt0]
  Create MAP files?                                   no
  EXCLUDE files?                                      yes
  List files as they are backed up?                   no 
  Verify readability if tape device?                  no 
  Generate new / file?                      yes
  EXPAND /tmp if needed?                              yes
  Disable software packing of backup?                 yes
  Backup extended attributes?                         yes
  Number of BLOCKS to write in a single output       []  
     (Leave blank to use a system default)
  Location of existing mksysb image                  []
  File system to use for temporary work space        []  
     (If blank, /tmp will be used.)
  Back up encrypted files?                            yes
  Back up DMAPI filesystem files?                     yes

When the fields have been correctly set, press Enter to begin the backup.

A progress indicator will indicate when the backup is running, and when it has completed, you will receive either an OK or Failed completion status message.

After creating the mksysb, you should verify the tape. The verification consists of reading the information stored on the tape back into the system.

Verifying the mksysb Tape – AIX

To verify the mksysb tape:

1. At the command prompt (#), enter the following command:
# smit lsmksysb

2. Leave the tape in the drive and press Esc-4 to select the device name in the second field on this screen.

The default for this field is /dev/rmt0.
If your primary tape drive is another device, press Esc-4 to select the name in this field.

Leave all other fields at their default values

The verification process begins.
You can let it run to completion or stop it by using Ctrl-C. It will take quite a while to stop, so be patient. If you stop the verification it will eventually give you an error message of “failed,” which in this case only means that you stopped the verification.
An “OK” in the upper left corner of the screen indicates a successful readback.

3. Press Esc-3 until you are back at the # prompt to get out of mksysb process.

4. Eject your mksysb tape.
