[Notes]

After executing this command, be sure to reboot the system.
Do not execute this command when the environment setting is completed. If executed, there is a possibility that a conflict will occur in the definition information, which makes it not possible to work properly. In this case, delete the definition information by a resethanet command and set the environment again. See "7.20 resethanet Command" for the detail of a resethanet command.
Recovery can be made exclusively on the same system configuration where the configuration file is backed up.

After recovering the configuration file, if a numeric string is specified as the host name, change the numeric string to the IP address before rebooting the system.

Here is the example to change a numeric string to the host name by using hanetconfig.

1) Check the current configuration status.

  # /opt/FJSVhanet/usr/sbin/hanetconfig print
  [IPv4,Patrol / Virtual NIC]

   Name        Hostname        Mode Physical ipaddr   Interface List
  +-----------+---------------+----+-----------------+---------------------------+
   sha0        123456           d   123457            eth2,eth3

  [IPv6]

   Name        Hostname/prefix                   Mode Interface List
  +-----------+---------------------------------+----+---------------------------+

2) Use the modify command to change a numeric string used as the host name

   This is when changing the numeric string to the IP address.
     Change 123456 to 0.1.226.64
     Change 123457 to 0.1.226.65
   
  # /opt/FJSVhanet/usr/sbin/hanetconfig modify -n sha0 -i 0.1.226.64 -e 0.1.226.65

3) Confirm the changed configuration status.

  # /opt/FJSVhanet/usr/sbin/hanetconfig print
  [IPv4,Patrol / Virtual NIC]

   Name        Hostname        Mode Physical ipaddr   Interface List
  +-----------+---------------+----+-----------------+---------------------------+
   sha0        0.1.226.64       d   0.1.226.65        eth2,eth3

  [IPv6]

   Name        Hostname/prefix                   Mode Interface List
  +-----------+---------------------------------+----+---------------------------+

[Examples]

The following shows an example of restoring a file (/tmp/hanet20041231.bk) created using the backup command.
