NAME

       zfcp_show - show information about the SAN environment.

SYNOPSIS

       zfcp_show [-oOtnvcdh] [-a <busid|fc_host|S_ID|WWPN>] [-i <domain-ID>] [-p <attached-port>]

DESCRIPTION

       zfcp_show  is  primarily  used  to  get an overview of the connected storage area network.
       Depending on the provided command line switches  the  information  includes  participating
       interconnect  element names, their type (e.g. switch, bridge, hub) the amount of available
       ports, their status and the potentially connected node ports along with  their  port  name
       (WWPN) and node port ID. In addition the topology of the SAN can be displayed by providing
       the interconnect element ports which are used to link between the switches.  The  provided
       information  can  become  very huge, therefore a variety of switches are provided to limit
       the output to the data of interest.

OPTIONS

       -a <adapter>
              source adapter specified by busid, fc_host, S_ID or WWPN.

       -i <ID>
              show only information about domain <ID>.

       -p <port>
              show only information about attached port <port>.

       -o     show online ports only.

       -O     show offline ports only.

       -t     show topology information only.

       -n     show local name server information only.

       -c     provide the information as CSV output.

       -v     Generate verbose output.

       -d     provide some debug output.

       -h     Print help message and exit.

EXAMPLES

       zfcp_show -t
              Only show the topology information. The output is a brief  listing  describing  how
              the  various  switches, bridges etc are connected to each other to form the storage
              area network (SAN).

       zfcp_show -a 0.0.3c02
              Provide the standard information but use the adapter with  the  busid  0.0.3c02  to
              send the request.

       zfcp_show -a host0
              Provide the standard information but use the adapter with the fc_host host0 to send
              the request.

       zfcp_show -a 0x656000
              Provide the standard information but use the adapter with  the  S_ID  h0x656000  to
              send the request.

       zfcp_show -a 0x500507630300c562
              Provide   the   standard   information   but   use   the   adapter  with  the  WWPN
              0x500507630300c562 to send the request.

       zfcp_show -d
              This command line switch is only to be used in case the raw requests and  responses
              send and received from the management server are required.

       zfcp_show -n
              The  local  name  server  (directory  server)  query  can  be used to receive basic
              information about the attached SAN when no management server access  is  available.
              The  output  shows  all ports of the local zone with their corresponding WWPN, D_ID
              (destiantion ID), the port type and, if available, the supported protocols.
