Several prompts will suggest a default value in brackets that can be accepted by simply pressing

enter.

Is this the Primary CSN (yes/no)? [yes]:: This prompt allows specification of whether

or not the CSN is a primary or secondary CSN. The default value is yes. Administrators should

take care to ensure that only a single primary CSN is configured on the internal network to prevent

conflicts with both DHCP and DX Storage netboot configuration. The primary server must be

configured prior to configuration of a secondary. DHCP is not started on the secondary CSN.

Half of the NIC ports on this system will be bonded and assigned to the

external network. The following questions configure the external network:

Enter the CSN IP address []:

This parameter requires entry of an external IP address for the CSN node. The entered address

must be in a valid w.x.y.z format and must not already be in use on the network.

Enter the cluster IP address. This IP address will remain with the Primary

CSN in the event of a CSN failover []: This parameter requires entry of an external IP

address for the CSN cluster address. This well-known address remains with the primary CSN in the

event of a failover, meaning the cluster can always be reached at this address. The entered address

must be in a valid w.x.y.z format and must not already be in use on the network.

Enter the subnet mask [255.255.255.0]: This parameter requires entry of the subnet

mask for the external network that corresponds with the entered IP address. The default is

255.255.255.0.

Enter the gateway IP address []: This parameter requires entry of the gateway

associated with the entered IP address for the external interface.

Half of the NIC ports on this system will be bonded and assigned to the

internal network. The following questions configure the internal network:

Enter the network address, e.g. 192.168.100.0 (small network),

192.168.0.0, 172.20.0.0 (large network) []:

This parameter allows specification of the network interface that should be used for the internal

network. Enter an interface in the format of 192.168.100.0 to use a small interface that will support

128 DX Storage nodes. Enter an interface in the format of 192.168.0.0 or 172.20.0.0 to use a larger

network that will support much larger DX Storage clusters. The entered interface will be divided

between the CSN(s) and privileged applications on the internal network and the DX Storage nodes.

The initial configuration process automatically creates multiple alias IP addresses on the internal

network for use by various system services and reserves similar IP addresses for a Secondary

CSN.

Enter a list of IP addresses (separated by spaces) for external name

servers [8.8.8.8 8.8.4.4]: This parameter allows specification of one or more DNS servers

for the external interface. Entries must be separated by spaces. Publicly available name servers

have been defaulted.

Enter a list of IP addresses or server names (separated by a space) for

external time servers [0.pool.ntp.org 1.pool.ntp.org 2.pool.ntp.org]: This

parameter allows specification of one or more NTP servers for the external interface. The defaults

are public NTP servers.

Enter a unique storage cluster name. This name cannot be changed once

assigned. A fully qualified domain name is recommended []: This parameter
