WAAS Central Manager config backup/restore

WAAS System を管理する Central Manager の config の backup 、restore 方法を紹介します。

Central Manager は各 Application Accelerator の設定情報を保持しているため、Application Accelerator については、基本的なネットワーク設定情報を記録しておくだけで構いません。Application Accelerator の recovery 方法については、別のドキュメントで紹介します。

config backup方法:

1) Central Manager の CLI にログインし、EXEC mode で "cms database backup" コマンドを実行します。

赤字で記したように、作成された backup file 名が表示されます。

WAE7326-A#cms database backup
Creating database backup file cms-db-09-26-2010-02-42_4.2.1.0.38.dump
Backup file cms-db-09-26-2010-02-42_4.2.1.0.38 is ready.
Please use `copy' commands to move the backup file to a remote host.

2) 作成された backup file を "dir" コマンドで確認した後、"copy disk ftp" コマンドで ftp server に保存し、backup は完了です。

restore 方法:

1) restore を行う WAE が工場出荷状態もしくは Application Accelerator として利用していた場合は、Central Manager として機能するよう "device mode" コマンドで設定し config save 後、再起動します。

NO-HOSTNAME#show device-mode current
Current device mode: application-accelerator
NO-HOSTNAME#conf t
NO-HOSTNAME(config)#device mode ?
  application-accelerator  Configure device to function as a WAAS Engine.
  central-manager          Configure device to function as a WAAS Central
                           Manager.
NO-HOSTNAME(config)#device mode central-manager ?
  <cr>
NO-HOSTNAME(config)#device mode central-manager
The new configuration will take effect after a reload
NO-HOSTNAME(config)#end
NO-HOSTNAME#copy running-config startup-config
NO-HOSTNAME#
NO-HOSTNAME#reload
Proceed with reload?[confirm]

2) backup ファイルを ftp server から download する為に、ネットワークの設定を行います。

NO-HOSTNAME#config t
NO-HOSTNAME(config)#interface gigabitEthernet 1/0
NO-HOSTNAME(config-if)#ip address 192.168.62.41 255.255.255.0
NO-HOSTNAME(config-if)#exit
NO-HOSTNAME(config)#ip default-gateway 192.168.62.254
NO-HOSTNAME(config)#end
NO-HOSTNAME#ping 192.168.61.13
PING 192.168.61.13 (192.168.61.13) 56(84) bytes of data.
64 bytes from 192.168.61.13: icmp_seq=1 ttl=127 time=1.14 ms
64 bytes from 192.168.61.13: icmp_seq=2 ttl=127 time=0.669 ms

3) "copy ftp disk" コマンドで、ftp server から backup file を download します。

NO-HOSTNAME#copy ftp disk ?
  Hostname or A.B.C.D  FTP server's IP address
NO-HOSTNAME#copy ftp disk 192.168.61.13 ?
  WORD  Remote file directory
NO-HOSTNAME#copy ftp disk 192.168.61.13 / ?

3) "dir" コマンドで download した backup file を確認した後、"cms database restore" コマンドで backup file を指定します。

Overwrite current key manager configuration/state with one in backup ? の質問には yes と答え、

Choose type of restoration では、通常 1 を入力して全ての CLI 設定を元に戻します。

WAE7326-A#conf t
WAE7326-A(config)#cms enable
Please preserve running configuration using 'copy running-config startup-config'.
Otherwise management service will not be started on reload and node will be shown
