SYNOPSIS

fcnsq host --gpn port_id [-q | --quiet]

DESCRIPTION

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.
