/sys$common/syshlp/SCACP$HELP.HLB  —  SET  CHANNEL
    Sets CHANNEL management parameters, currently limited to priority
    values.

                                   NOTE

       If a LAN device/IP interface is disabled for use by
       cluster communications, all channels associated with that
       device/interface are deleted. This means that all management
       settings for that device and its associated channels will be
       deleted.

    Format

      SET CHANNEL  nodename

1  –  Parameter

 nodename[,...]

    Includes channels to specific nodes, which you can use wildcards
    to specify. Each node name can be accompanied by optional
    qualifiers to specify local and remote device names. If no local
    or remote device name is specified, all channels to the specified
    node name are included.

    Use the SHOW CHANNEL command to display node names and local and
    remote device names.

2  –  Qualifiers

2.1    /EXCLUDE

       /EXCLUDE=(nodename[,...])

    Excludes channels to specific nodes, which you can use wildcards
    to specify. Each node name can be accompanied by optional
    qualifiers to specify local and remote device names. If no local
    or remote device name is specified, all channels associated with
    the specified node are included.

2.2    /LOCAL_DEVICE

       /LOCAL_DEVICE=(landevicename/IPinterfacename[,...])

    Specifies a LAN device/IP interface that identifies the local end
    of the channel; you can use wildcards to specify LAN devices/IP
    interfaces.

    Use the SHOW CHANNEL command to display node names and local and
    remote device names, or use the SHOW LAN_DEVICE/SHOW IP_INTERFACE
    command to display device names.

2.3    /PRIORITY

       /PRIORITY=n

    Sets the management priority value for channels to selected
    nodes. n can be a value between -128 and +127. Suggested values
    are:

       2 to cause channels to be preferred
       -2 to exclude channels

                                   NOTE

       Starting with OpenVMS Version 7.3-2, a channel whose
       priority is -128 is not used for cluster communications.
       The priority of a LAN channel is the sum of the management
       priority assigned to the local LAN device and the channel
       itself. Similarly the priority of IP channel is the sum of
       the management priority assigned to local IP interface and
       channel itself. Therefore, you can assign any combination
       of channel and LAN/IP device management priority values to
       achieve a total of -128.

                                 CAUTION

       If you set the priority of all channels to -128, you totally
       disable use of the LAN/IP for cluster communication. This
       can cause the system to CLUEXIT.

2.4    /REMOTE_DEVICE

       /REMOTE_DEVICE=(landevicename/IPinterfacename[,...])

    Specifies a LAN device/IP interface that identifies the remote
    end of the channel; you can use wildcards to specify LAN/IP
    devices.

    Use the SHOW CHANNEL command to display node names and local and
    remote device names, or use the SHOW LAN_DEVICE/SHOW IP_INTERFACE
    command to display device names.

    Use the SHOW LAN_DEVICE/SHOW IP_INTERFACE command on the remote
    node to display remote device names.

3  –  Example

  SCACP> SET CHANNEL/PRIORITY=3 NODE5

      The command in this example sets the priorities of all channels
      to node NODE5 to 3.
