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".
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.
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".
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.
Create a physical server for NS Appliance
Refer to "3.3.3 Creating Physical Servers (When Using the Internal Disk of a Server)".
Create an NS Appliance on a physical server using the rcxnetworkservice create command
Refer to "3.5 Creating NS Appliances".
Configure the environment for the created NS Appliance using the rcxnetworkservice setup command
Refer to "3.6 Configuring NS Appliances".
Restore NS Appliance configuration files
Refer to "10.2.3 Restoration of Network Devices" in the "Operation Guide CE".
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:
Connect to the NS Appliances which compose the redundancy pair using a Telnet or SSHv2 client.
Execute the following command to synchronize the definition.
