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.
