If you are using iSCSI-attached hosts with the SAN Volume Controller cluster,
you can the command-line interface (CLI) to optionally configure the
address for the Internet Storage Name Service (iSNS) server for the
cluster. Host systems use the iSNS server to manage iSCSI targets
and for iSCSI discovery.
- To specify an IPv4 address for the iSCSI storage name service
(SNS), enter the following CLI command:
svctask chcluster -isnsip sns_server_address
where sns_server_address is
the IP address of the iSCSI storage name service in IPv4 format.
- To specify an IPv6 address for the iSCSI storage name service
(SNS), enter the following CLI command:
svctask chcluster -isnsip_6 ipv6_sns_server_address
where ipv6_sns_server_address is
the IP address of the iSCSI storage name service in IPv6 format.
After you configure the iSNS server address for the cluster,
you can configure cluster iSCSI authentication.
Note: To help in
problem determination, this step can be delayed until after the first
one or two hosts have been configured and their connectivity has been
tested without authentication configured.
