NAME
     utfwadm -  Sun Ray firmware version management

SYNOPSIS
     /opt/SUNWut/sbin/utfwadm  { -A  | -D  }  { -a  | -s enetSuf-
     fix   | -e enetAddr  }  -n interf   [ -n interf ]  ...  [ -f
     firmware ]

     /opt/SUNWut/sbin/utfwadm  -P

     /opt/SUNWut/sbin/utfwadm  -R

DESCRIPTION
     The utfwadm command manages firmware  upgrades  to  Sun  Ray
     appliances.  The  appliances are capable of loading firmware
     upgrades and programming new firmware into their flash  PROM
     memory.

     The firmware file contains a version  string  which  can  be
     extracted  from  the file using the what(1) command. When an
     appliance is powered on, the firmware obtains an IP  address
     and other configuration information using the DHCP protocol.
     Part of the configuration information is  a  DHCP  variable,
     NewTVer.  If this variable is defined, the firmware compares
     it with its own version string. If it is not the  same,  the
     firmware  initiates  an  upgrade  which replaces the current
     firmware with the new version.

     The utfwadm command must be run when a new firmware  version
     is  installed  to  set  the  NewTVer  variable and force the
     appliances to load the  new  version  on  their  next  power
     cycle. The DHCP facility allows variables such as NewTVer to
     be set on either a per-network  or  per-unit  basis  in  the
     dhcptab(4)  file, and utfwadm allows firmware upgrades to be
     targeted either to entire Sun Ray subnetworks or  individual
     appliances.  The  Sun  Ray subnetworks must have been previ-
     ously set up using the utadm(1M) command. The  command  must
     be run with super-user privileges.

OPTIONS
     The following options are supported

     -a    This causes the given operation to be applied  to  all
           units attached to the given interfaces.

     -A    Add the defined appliances to the list of units to  be
           upgraded  with  a  new firmware version. The following
           options determine which subset of the units should  be
           upgraded. This option sets the NewTVer variable in the
           appropriate context. It also  copies  files  from  the
           firmware  install  directory  into the boot directory,
           renaming them to contain their version strings.

     -D    Remove the defined appliances from the list  of  units
           to  be  upgraded. This option causes the NewTVer vari-
           able to be unset.

     -e enetAddr
           This causes the operation to be applied  to  only  the
           specified  unit  with  Ethernet  address given by ene-
           tAddr, where all six hex  bytes  of  the  address  are
           specified.

     -f firmware
           This option gives the pathname for the firmware to  be
           downloaded  to the appliances. If firmware refers to a
           file, the hardware version is extracted from the  ver-
           sion string within the file, and the file is copied to
           the /tftpboot directory to be downloaded only to  that
           version  of  the  hardware.  If  firmware  refers to a
           directory, then all files  named  ``Corona*''  in  the
           directory  are  copied to the /tftpboot directory with
           their version strings appended. If the  -f  option  is
           not given, a default location is used.

     -n interface
           Apply the given operation to units  connected  to  the
           Ethernet  interface interface. Multiple interfaces may
           be given, or the special keyword  all,  which  applies
           the operation to all configured Sun Ray interfaces.

     -P    This variant of the command prints out the version  to
           which each domain should be upgraded on the next power
           cycle. A domain may be either an  interconnect  subnet
           or  individual  appliance. If it is a subnet, then the
           Intf column lists the interface device. If  it  is  an
           individual  appliance,  then  its  Ethernet address is
           given in the Domain column, and the Intf  column  con-
           tains the interface name.

     -R    Remove the firmware files that were  copied  into  the
           boot directory.

     -s enetSuffix
           This causes the operation to be applied  to  only  the
           specified  unit, where enetSuffix is given as the last
           three hex bytes of the Ethernet address. The hex  pre-
           fix "0x080020" is added to the address.

     The -z option is RESERVED for use  by  the  Sun  Ray  Server
     Software and should not be used.

FILES
     These are the files used by this command:

     /var/dhcp/dhcptab
           file or NIS+ table

     /tftpboot
           default location of firmware boot files
