Restore configuration data for f5 by .ucs file

1.首先确保已经有备份的.ucs文件，备份方法：通过配置工具的archives菜单或b config save filename

2.若是将该文件在本机系统恢复，执行如下步骤：

  a. 将ucs文件拷贝到某个目录，如/var/local/ucs/ 下

   b.将系统主机名设置为做ucs备份时的系统主机名，即保证hostname与以前的主机名一致

   c.执行 b config install /var/local/ucs/***.ucs

[root@ltm:Active] config # b config install 20080308.ucs
Saving active configuration...
Current configuration backed up to /var/local/ucs/cs_backup.ucs.

   d.验证ssh keys是否同SCCP和BIGIP同步 : keyswap.sh sccp

   e.reboot

其中C步骤中如有以下错误：

      Dec  8 12:00:00 bigip1 mcpd[2395]: 01070608:0: License is not operational

      (expired or digital signature does not match contents).

      Loading the new /config/BigDB.dat failed.

      01080023:3: Error return while getting reply from mcpd: 0x1070370,

      01070370:3: Failover (redundant mode) is not licensed.

      After updating your license, run

      loaddb -local /config/BigDB.dat.cs

则说明license与ucs里的不同，需要更新（一般都出现在向不同机器上恢复时），通过以下方法解决：

  Re-license the system.

  Finish loading the BigDB.dat information by typing the following command:

      loaddb -local /config/BigDB.dat.cs

在新系统上恢复配置：

大致步骤差不多，就是先做一个系统，然后config命令，配置一个IP以便将UCS传上去。

To install the operating system and restore configuration data to a new system, perform the following steps:

   1. Network boot the system software from the CD-ROM drive.

   2. After the system software installs, reboot the system by typing the following command:

      reboot

   3. Connect to the serial port.

   4. From the command line,type the following command:

      config

   5. Follow the prompts to configure the system with an IP address.

   6. Copy the UCS archive file to the system.

   7. Set the hostname of the system to match the hostname of the system on which the UCS archive was created, by typing the following command:

      hostname <hostname>

      Important: If you do not set the hostname to match the original hostname, the configuration restoration will fail.

   8. Restore the configuration from the UCS archive, by typing the following command, replacing <filename> with the name of your UCS archive file:

     bigpipe config install <filename>

      Important: If you are restoring the backup on a different device than the system on which the backup was created, such as an RMA system, the configuration load will fail with a license error, and a BigDB.dat load error similar to the following will be displayed:

      b config install /var/local/ucs/backup.ucs

      Installing full configuration on host bigip1.askf5.com

      Creating UCS for config save request...

      Dec  8 12:00:00 bigip1 mcpd[2395]: 01070608:0: License is not operational

      (expired or digital signature does not match contents).

      Loading the new /config/BigDB.dat failed.

      01080023:3: Error return while getting reply from mcpd: 0x1070370,

      01070370:3: Failover (redundant mode) is not licensed.

      After updating your license, run

      loaddb -local /config/BigDB.dat.cs

  9.  If you are running BIG-IP version 9.x software on a 1500, 3400, 6400, 6800, or 8400 hardware platform, type the following command to verify that the new or replaced SSH keys from the UCS file are synchronized between the BIG-IP and the SCCP:

      keyswap.sh sccp

  10. Reboot the system, by typing the following command:

      reboot

If you installed this system on the same device on which the backup was created, after the system reboots, it will load the restored configuration; however, if you restored the backup on a different device, and received the errors noted in step 8, then perform steps 11 and 12:

    11. Re-license the system.

    12. Finish loading the BigDB.dat information by typing the following command:

      loaddb -local /config/BigDB.dat.cs
