Cluster Setup Wizard for a Single-Node Cluster

*Data ONTAP Version 8.2.1 RC1

Scenario: A new Single-Node 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
Location

Node Name
Node Mgmt Port
Node Mgmt IP




4. System Config Backup for Single Node Clusters (can be skipped)
Destination URL (http/https/ftp/tftp)

URL Access Username

URL Access Password


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? yes

Step 1 of 5: Create 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 not be enabled on a non-HA system.

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

Enter the system config backup destination address (or press enter to skip this step):
Enter the username: SEE TABLES ABOVE
