Add a Device to a Device Cluster

Now that you have associated a device cluster to its offline configuration you can add devices to the device cluster.

Pre-requisites: A device is eligible to be added to a device cluster if it meets the following criteria:

• The device must contain a platform and software version that matches the Offline Configuration.
• The device must be accessible through SSH over the network.
• The device has all required entitlements enabled, and licenses installed, as needed, to provide any services enabled by the Offline Configuration.

Note:

Ensure that any device that is added to the cluster is not currently being managed by SEM. If a device is being managed by SEM, remove it from SEM so that you can add it to the device cluster.

1. Expand the Device Manager slider and click Devices.
2. In the Managed Devices - Group View pane, select to expand the device cluster to which you are adding a device.
3. Select the device cluster and click Add.
4. In the Add Device to scalability group dialog box, complete the following fields:

   Name	Description
   Name	The device name.
   Primary IP address field	The primary IP address for this device.
   Secondary IP address field	The secondary IP address. This field appears if you have a high-availability (HA) device pair only.
   User Name field	The device user name.
   User Password field	The device password.
   SNMP agent mode drop-down list	Select the SNMP version number that the SNMP agent supports and click Load. Valid versions are v1, v2 and v3. If you select v3, authentication fields for SNMP version 3 appear. See below for more information about these fields.
   SNMP port field	The SNMP port number. The default SNMP port number is 161.
   SNMP community name field	Note: This field applies only to SNMP version 1 and 2. Enter the SNMP community name for this device, which is the name of an active community where the device can send or receive SNMP performance and fault information. Note: For a device cluster, the SNMP community name must match an SNMP community that is defined in the offline configuration, which must also contain the IP addresses of each SDM server cluster node.
   SNMPv3 user name field	The SNMP version 3 user name.
   SNMPv3 authentication protocol drop-down list	Select the SNMP version 3 authentication protocol: SHA—Secure hash algorithm (SHA-1). MD5—MD5 hash algorithm. NONE
   SNMPv3 authentication password field	The SNMP version 3 authentication password.
   SNMPv3 privacy protocol drop-down list	Select the SNMP version 3 privacy protocol: DES—Data encryption standard algorithm (DES) for the encryption of electronic data. AES128—Advanced encryption standard (AES) encryption algorithm. NONE
   SNMPv3 privacy password field	The SNMP version 3 privacy password.

5. Click Check Device to verify that the device has the same software version that the offline configuration uses.
6. Click Next to configure the necessary data variables offered by the offline configuration.
7. In the next dialog box, enter the device-specific parameters for each data variable that you are provided (through the offline configuration).

   Note:

   See the Create Data Variables to Support Device Specific Values section for more information about how data variables are created in an offline configuration.
8. The device must already be active and on the network for the activation process to start (it has already booted). Click Finish to start the activation process.
   In the Managed Devices table, enable the hidden Activation Status column to see the device status. If the device activates successfully, the Activated status displays. If the device failed to activate, the Activation Failed status displays.

   For example, one scenario for a device that fails to activate could be if it was re-booted and failed to re-boot during the activation process.
