Outlines how to create multiple names that can be used by end users to connect to a Qumulo cluster
- Cluster running Qumulo Core with Windows DNS Server already configured
- Microsoft DNS Manager snap-in tool installed
- Access to the command line with Administrator rights on Windows AD/DNS Server
NOTE: DNS entries will be automatically created from the node used to add the cluster to Active Directory and can be removed without issue during configuration.
Based on your workflow needs and existing environment, configuring multiple names for your Qumulo cluster offers many benefits. You can provide redundancy and fallbacks for connecting clients, increase availability, or easily carry over your existing infrastructure with multiple namespaces from a legacy storage system when transitioning to Qumulo.
Many times when Qumulo is implemented inside an organization, it is replacing legacy storage systems that are addressed by multiple names. In this scenario, moving all of those applications over to a new single name for a Qumulo cluster can be an extremely difficult process that can be handled inside DNS.
The following steps allow you to maintain your existing server names so that transitioning to a single name space is not required. Before you begin, verify that DNS snap-in is already installed on your system.
- Log on and open the DNS Manager snap-in tool.
- Click Start, hover over Administrative Tools, and select DNS.
- Click the arrow next to the DNS server name to expand contents in the console tree.
- Expand the Forward Lookup Zones first followed by the domain name.
- Right-click on the appropriate zone and click Properties.
- Type in the Name you want displayed (e.g., app1.companyx.com) to end users connecting to your Qumulo cluster.
- Enter the name of the current Qumulo cluster that is already configured in DNS (e.g.,qumulo.companyx.com) in the Fully Qualified Domain Name (FQDN) for the Target host field.
- Click Done.
- Repeat the steps for each different name that needs to be created on your Qumulo cluster.
- Verify end user connections with the new namespace by opening a terminal window and specifying the new name in the nslookup command.
- Lastly, configure authentication access to ensure re-authentication is not required for end users by using the setspn tool command to register the SPN for the newly created DNS CNAME.
SETSPN -a host/app1 qumulo
SETSPN -a host/app1.companyx.com qumulo
NOTE: Advanced configurations of hiding shares, share permission and access based enumeration (ABE), and restricting access to Exports and SMB Shares will ensure that users will see only what they have been assigned access to on any given name you've assigned to the Qumulo cluster.
You should now be able to successfully create multiple names that end users will be able to use to connect to a Qumulo cluster
