After you remove a discovery domain set, its discovery domains remain. A discovery domain must be a member of at least one discovery domain set.
Use the “iSNS Server Management” RBAC profile to obtain the authorizations needed for managing the iSNS service.
Roles contain authorizations and privileged commands. For more information about roles, see Configuring RBAC (Task Map) in System Administration Guide: Security Services.
List the discovery domain sets to identify the one you want to remove.
#isnsadm list-dd-set -v
Remove the discovery domain set.
