5.3 Maintenance When Failure Occurs on Dedicated Servers for NS Appliances

This section explains the recovery procedure for when a dedicated server dedicated for NS Appliances used in a single configuration fails.

When using an internal disk, it is necessary to back up the network device file for NS Appliances using the network device file management functions before performing the recovery operation.

For details on the network device file management function, refer to "10.2 Backup and Restoration of Network Devices" in the "Operation Guide CE".

  1. Change the status of the NS Appliance to maintenance mode

    On the ROR console, change the status of all NS Appliances on the failed physical server to maintenance mode.

  2. Maintain hardware

    Replace failed servers.

    • When using the BX series

      Refer to "9.2 Blade Server Maintenance" in the "Operation Guide CE".

    • When using the RX series

      Refer to "9.3 Maintenance for Servers Other Than Blade Servers" in the "Operation Guide CE".

  3. Recover NS Appliances

    It is not necessary to perform recovery operations of NS Appliances when using SAN storage.

    It is necessary to create physical servers for NS Appliances again when using an internal disk.

  4. Release the maintenance mode of NS Appliances

    On the ROR console, release the statuses of all NS Appliances on the failed physical server from maintenance mode.

    For the procedure to change or release maintenance mode, refer to "22.1 Switchover of Maintenance Mode" in the "User's Guide for Infrastructure Administrators (Resource Management) CE".


Information

When using a redundancy configuration, it is necessary to synchronize the definitions of the NS Appliances that compose the redundancy configuration pair before releasing the NS Appliance to perform maintenance on from maintenance mode, using the following procedure:

  1. Connect to the NS Appliances which compose the redundancy pair using a Telnet or SSHv2 client.

  2. Execute the following command to synchronize the definition.

    admin
    Password: Administrator Password
    sync cluster
