sys_attrs_clua(5)
NAME
  sys_attrs_clua - clua subsystem attributes

DESCRIPTION
  This reference page lists and describes attributes for the cluster alias
  (clua) kernel subsystem. Refer to the sys_attrs(5) reference page for an
  introduction to the topic of kernel subsystem attributes.

  debug
      Controls which cluster alias error messages are printed.

      Do not modify the default setting for this attribute unless instructed
      to do so by support personnel or by patch kit documentation.

      Supported operations: Query; Configure at boot time; Reconfigure at run
      time

      Default value: 0

      Minimum value: 0

      Maximum value: 11

  enable
      When set to 1, enables the cluster alias subsystem. A value of 0 (zero)
      disables the cluster alias subsystem.

      Do not modify the default setting for this attribute unless instructed
      to do so by support personnel or by patch kit documentation.

      Supported operations: Query; Reconfigure at run time

      Default value: 1

      Minimum value: 0

      Maximum value: 1

  disable
      When set to 1, sets enable to 0 (zero), thus effectively disabling the
      cluster alias subsystem.

      Do not modify the default setting for this attribute unless instructed
      to do so by support personnel or by patch kit documentation.

      Supported operations: Reconfigure at run time

  init_aliasd
      When set to 0 (zero), initializes the alias daemon.

      Do not modify the default setting for this attribute unless instructed
      to do so by support personnel or by patch kit documentation.

      Supported operations: Configure at boot time; Reconfigure at run time

  max_aliasid
      Determines the maximum number of cluster aliases allowed. Although the
      theoretical maximum is 102,400 aliases, the practical upper limit is
      memory-restricted. There are no known issues with the use of 100 or so
      aliases.

      When increasing the value of this attribute, be sure to increase it
      consistently on all cluster members before using the additional
      aliases.

      Supported operations: Query; Configure at boot time; Reconfigure at run
      time.

      Default value: 8

      Minimum value: 2

      Maximum value: 102400

  udp_min_lockaside
      The low water mark for refilling the UDP lockaside locked port list.
      For example, if udp_min_lockaside=25 and there are 24 ports currently
      locked, the kernel will lock ports until udp_max_lockaside ports are
      locked.

      Do not modify the default setting for this attribute unless instructed
      to do so by support personnel or by patch kit documentation.

      Supported operations: Query; Configure at boot time; Reconfigure at run
      time.

      Default value: 25

      Minimum value: 1

      Maximum value: 100

  udp_max_lockaside
      Specifies the max number of TCP ports that are locked for use by the
      cluster alias when allocating ephemeral ports.

      Do not modify the default setting for this attribute unless instructed
      to do so by support personnel or by patch kit documentation.

      Supported operations: Query; Configure at boot time; Reconfigure at run
      time.

      Default value: 100

      Minimum value: 1

      Maximum value: 100

  tcp_min_lockaside
      The low water mark for refilling the TCP lockaside locked port list.
      For example, if tcp_min_lockaside=25 and there are 24 ports currently
      locked, the kernel will lock ports until tcp_max_lockaside ports are
      locked.

      Do not modify the default setting for this attribute unless instructed
      to do so by support personnel or by patch kit documentation.

      Supported operations: Query; Configure at boot time; Reconfigure at run
      time.

      Default value: 25

      Minimum value: 1

      Maximum value: 100

  tcp_max_lockaside
      Specifies the max number of TCP ports that are locked for use by the
      cluster alias when allocating ephemeral ports.

      Do not modify the default setting for this attribute unless instructed
      to do so by support personnel or by patch kit documentation.

      Supported operations: Query; Configure at boot time; Reconfigure at run
      time.

      Default value: 100

      Minimum value: 1

      Maximum value: 100
