Cluster Setup Wizard for a 2-Node Switchless Cluster

*Data ONTAP Version 8.2.1 RC1

Scenario: A new 2-Node Switchless Cluster CDOT implementation

This post continues from the point of the physical rack and stack, power-on, shelf-IDs set, and all cabling (back-end and front-end) having been completed, including any Cluster Interconnect and Management Switch configurations having been completed. So, all we are left with is to complete the Cluster Setup Wizard, configure the Service Processor, and that’s it - basic cluster setup complete and we’re ready for creating SVMs and provisioning data storage!

This post will cover what information is required beforehand to complete the Cluster Setup Wizard (and show an abridged version of the cluster setup script to give the why).

Site Information

List the networks used for Cluster Management IP, Node Management IP, and Service Processor IP.

1. Networks
Subnet
Netmask
Gateway
Purpose





2. DNS
DNS Domain Names

Name Server IP Addresses


Cluster Information

1. Licenses
SO Number

Serial Number
Cluster S/N
Model
Protocol Name
License Key

















2. Cluster
Cluster Administrator’s (username “admin”) Password

Cluster Name
Cluster Mgmt Port
Cluster Mgmt IP




3. Node(s)
Location

Node Name
Node Mgmt Port
Node Mgmt IP







I. Post Cluster Setup Wizard
·         The Cluster Setup Wizard will name nodes CLUSTERNAME-XX, with XX being consecutive numbers from 01 to 24. To rename via the clustershell ::>
node rename -node OLDNAME -newname NEWNAME

II. Service Processor Configuration
·         Post Cluster Setup Wizard, as a minimum, before leaving site, the Service Processor must be configured and reachable. Configure via the clustershell ::>
system node service-processor network modify -address-type IPv4/IPv6 -node NODENAME -enable true/false -dhcp v4/none -ip-address X.X.X.X -netmask X.X.X.X -gateway X.X.X.X
Node Name
Address Type (IPv4/IPv6)
Enable (true/false)
DHCP (v4/none)
IP Address











Cluster Setup Wizard - Cluster Create

Do you want to create a new cluster or join an existing cluster? create
Do you intend for this node to be used as a single node cluster? no
Will the cluster network be configured to use network switches? no

System Defaults (example FAS62XX):
Private cluster network ports [e0c,e0e].
Cluster port MTU values will be set to 9000.
Cluster interface IP addresses will be automatically generated.

Do you want to use these defaults? yes

Step 1 of 5: Create a Cluster

Enter the cluster name: SEE TABLES ABOVE
Enter the cluster base license key: SEE TABLES ABOVE

Step 2 of 5: Add Feature License Keys

Enter an additional license key: SEE TABLES ABOVE

Step 3 of 5: Set Up a Vserver for Cluster Administration

Enter the cluster administrator's (username "admin") password: SEE TABLES ABOVE

Retype the password: SEE TABLES ABOVE

Enter the cluster management interface port: SEE TABLES ABOVE
Enter the cluster management interface IP address: SEE TABLES ABOVE
Enter the cluster management interface netmask: SEE TABLES ABOVE
Enter the cluster management interface default gateway: SEE TABLES ABOVE

Enter the DNS domain names (comma separated): SEE TABLES ABOVE
Enter the name server IP addresses (comma separated): SEE TABLES ABOVE

Step 4 of 5: Configure Storage Failover (SFO)

SFO will be enabled when the partner joins the cluster.

Step 5 of 5: Set Up the Node

Where is the controller located: SEE TABLES ABOVE

Enter the node management interface port: SEE TABLES ABOVE
Enter the node management interface IP address: SEE TABLES ABOVE
Enter the node management interface netmask: SEE TABLES ABOVE
Enter the node management interface default gateway: SEE TABLES ABOVE

Cluster setup is now complete.

Cluster Setup Wizard - Cluster Join of 2nd Node

Do you want to create a new cluster or join an existing cluster? join

System Defaults (example FAS62XX):
Private cluster network ports [e0c,e0e].
Cluster port MTU values will be set to 9000.
Cluster interface IP addresses will be automatically generated.

Do you want to use these defaults? yes

Step 1 of 3: Join an Existing Cluster

Enter the name of the cluster you would like to join: SEE TABLES ABOVE

Step 2 of 3: Configure Storage Failover (SFO)

SFO is enabled.

Step 3 of 3: Set Up the Node

Enter the node management interface port: SEE TABLES ABOVE
Enter the node management interface IP address: SEE TABLES ABOVE
Enter the node management interface netmask: SEE TABLES ABOVE
Enter the node management interface default gateway: SEE TABLES ABOVE

Cluster setup is now complete.
