NAME
     hafence - CXFS cluster I/O fencing administration

SYNOPSIS
     hafence [ option ... ]

DESCRIPTION
     The hafence utility is used to administer the CXFS I/O fencing
     configuration stored in the CXFS cluster database.  Note that users would
     normally configure I/O fencing (as part of initial node definition) via
     the CXFS GUI or cmgr command, as described in the CXFS Version 2 Software
     Installation and Administration Guide.  Use of hafence is restricted to
     users with the CAP_SYSINFO_MGT capability.

     The -q and -v (verbose) options query the status of all configured Fibre
     Channel Switches and display port types, port status and HBA World Wide
     Numbers (WWNs).

     To define one or more switches in the CXFS cluster database, use the
     following command syntax:
                hafence -a -s myswitch -u user -p password -m mask
     where

     myswitch    is the hostname or IP address of the switch (the ethernet
                 interface for myswitch can be plugged into either the private
                 or public network for your cluster, but must be accessible to
                 all nodes in the cluster),

     user        is the username for telnet access to myswitch (factory
                 setting for Brocade is admin),

     password    is the password (factory setting is password), and

     mask        is the port mask (see CXFS Version 2 Software Installation
                 and Administration Guide), typically 0.

OPTIONS
     Hafence takes the following options:

     -h          print usage

     -q          query switch status (default)

     -v          verbose query: report status of all ports (implies -q)

     -a          add/change a switch in cdb (requires -s, -p and -u)

     -s switch   specify switch hostname for -a, -m, -p and -d

     -u username change saved user name in cdb for switch (requires -s)
     -p passwd   change saved password in cdb for switch (requires -s)

     -m mask     change saved mask (hex, default 0) in cdb for switch
                 (requires -s)

     -d          delete switch in cdb (requires -s)

     -U          update cdb for calling machine

     -r host     raise I/O fence for host

     -l host     lower I/O fence for host

     -S switch   show database entries for switch

     -V          show database entries for all switches
