fcnsq - Fibre Channel Name Server Query Tool
fcnsq host --gpn port_id [-q | --quiet] fcnsq host --gnn port_id [-q | --quiet] fcnsq host --gspn port_id [-q | --quiet] fcnsq host --gsnn wwpn [-q | --quiet] fcnsq ?
The fcnsq command performs Fibre Channel Name Server queries for a user-specified FC Host. The supported name server query commands include: Get Port Name (GPN), Get Node Name (GNN), Get Symbolic Node Name (GSNN), and Get Symbolic Port Name (GSPN) as described in FC-GS-3 for the Common Transport (CT) services. fcnsq takes the host bsg name as the input for the target host. Host bsg name must be a valid bsg device, e.g., "host12" as derived from /dev/bsg/fc_host12. For each name server query command, the argument is either a Port ID or a World Wide Port Name. Port IDs and World Wide Names must be specified in hexadecimal. To disable verbose output, use the --quiet option.
host --gpn port_id Get Port Name by Port ID for host. host --gnn port_id Get Node Name by Port ID for host. host --gspn port_id Get Symbolic Port Name by Port ID for host. host --gsnn wwpn Get Symbolic Node Name by World Wide Port Name for host. -q, --quiet Disable verbose output. ?
