SmartConnect service name

The SmartConnect service name field is displayed when you create or modify a subnet, as shown in the following figure. Click Cluster Management > Network Configuration to display the Create subnet dialog box, and then add a subnet under a specified groupnet. Alternatively, from the command-line interface, the SmartConnect service name field is displayed when you add or modify a subnet to a specified groupnet with the --sc-service-name option.

The SmartConnect service name field is an optional field to answer nameserver (NS), Start of Authority (SOA), and other DNS queries. It specifies the domain name corresponding to the SmartConnect Service IP (SSIP) address, serving as the glue record in the DNS delegation tying the NS and the IP address. The DNS delegation to SmartConnect consists of two DNS records, as listed in the following table:
Table 4. SmartConnect service name DNS records
DNS record
DNS field
DNS value
OneFS field
NS
Domain
cluster.company.com
SmartConnect Zone Name on the network pool (sc-dns-zone in the CLI)
Value
ns.cluster.company.com
SmartConnect Service Name on the subnet (sc-service-name in the CLI)
Description
This entry informs the DNS server the nameserver for the PowerScale cluster is this record at ns.cluster.company.com
A/AAAA
Domain
ns.cluster.company.com
SmartConnect Service Name on the subnet (sc-service-name in the CLI)
Value
1.2.3.4
SmartConnect Service IP address on the subnet (sc-service-addr in the CLI)
Description
This entry informs the DNS server the nameserver for the PowerScale cluster can be contacted at the 1.2.3.4 IP address specified as the A/AAAA Value.
Note: If a value is not provided for this field, SmartConnect reuses the domain name from the nameserver and Start of Authority queries as the nameserver hostname. If the sc-service-name on the cluster is different than the record in the DNS Delegation, DNS resolution failures can occur; thus, ensure that these records are synchronized.
