hanetbackup
[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.
The configuration file backed up in RHEL7 or earlier environments cannot be used to restore the configuration file in the RHEL8 environment.
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.
# /opt/FJSVhanet/usr/sbin/hanetrestore -f /tmp/hanet20041231.bk |
