Make a backup and edit the Sendmail Configuration File (/etc/sendmail.cf) to point to the correct SMTP host.
cp /etc/sendmail.cf /etc/sendmail.`date +%Y%m%d.%H%M%S`
In VI search for the “DSsmtp” string and make the change according to your system configuration.

The tool runs the mktcpip command in the background and makes the network available. Done!
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 192.168.2.2 00-00-9d-22-23-60
arp -s 192.168.2.2 00009d222360
- Ping the Digi device using the IP address just assigned:
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:
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 /image.data 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.
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.
