OCF_HEARTBEAT_IPADDR(7) 					OCF resource agents					   OCF_HEARTBEAT_IPADDR(7)

NAME

       ocf_heartbeat_IPaddr - Manages virtual IPv4 addresses (portable version)

SYNOPSIS

       IPaddr [start | stop | monitor | meta-data | validate-all]

DESCRIPTION

       This script manages IP alias IP addresses It can add an IP alias, or remove one.

SUPPORTED PARAMETERS

       ip
	   The IPv4 address to be configured in dotted quad notation, for example "192.168.1.1".  (unique, required, string, no default)

       nic
	   The base network interface on which the IP address will be brought online. .sp If left empty, the script will try and determine this
	   from the routing table. .sp Do NOT specify an alias interface in the form eth0:1 or anything here; rather, specify the base interface
	   only. .sp Prerequisite: .sp There must be at least one static IP address, which is not managed by the cluster, assigned to the network
	   interface. .sp If you can not assign any static IP address on the interface, modify this kernel parameter: sysctl -w
	   net.ipv4.conf.all.promote_secondaries=1 (or per device) .sp

	   (optional, string, default eth0)

       cidr_netmask
	   The netmask for the interface in CIDR format. (ie, 24), or in dotted quad notation 255.255.255.0). .sp If unspecified, the script will
	   also try to determine this from the routing table.  (optional, string, no default)

       broadcast
	   Broadcast address associated with the IP. If left empty, the script will determine this from the netmask.  (optional, string, no
	   default)

       iflabel
	   You can specify an additional label for your IP address here.  (optional, string, no default)

       lvs_support
	   Enable support for LVS Direct Routing configurations. In case a IP address is stopped, only move it to the loopback device to allow the
	   local node to continue to service requests, but no longer advertise it on the network.  (optional, boolean, default false)

       local_stop_script
	   Script called when the IP is released (optional, string, no default)

       local_start_script
	   Script called when the IP is added (optional, string, no default)

       ARP_INTERVAL_MS
	   milliseconds between ARPs (optional, integer, default 500)

       ARP_REPEAT
	   How many gratuitous ARPs to send out when bringing up a new address (optional, integer, default 10)

       ARP_BACKGROUND
	   run in background (no longer any reason to do this) (optional, boolean, default yes)

       ARP_NETMASK
	   netmask for ARP - in nonstandard hexadecimal format.  (optional, string, default ffffffffffff)

NAME

       ocf_heartbeat_IPaddr2 - Manages virtual IPv4 and IPv6 addresses (Linux specific version)

SYNOPSIS

       IPaddr2 [start | stop | status | monitor | meta-data | validate-all]

DESCRIPTION

       This Linux-specific resource manages IP alias IP addresses. It can add an IP alias, or remove one. In addition, it can implement Cluster
       Alias IP functionality if invoked as a clone resource.

       If used as a clone, you should explicitly set clone-node-max >= 2, and/or clone-max < number of nodes. In case of node failure, clone
       instances need to be re-allocated on surviving nodes. This would not be possible if there is already an instance on those nodes, and
       clone-node-max=1 (which is the default).

SUPPORTED PARAMETERS

       ip
	   The IPv4 (dotted quad notation) or IPv6 address (colon hexadecimal notation) example IPv4 "192.168.1.1". example IPv6
	   "2001:db8:DC28:0:0:FC57:D4C8:1FFF".

	   (unique, required, string, no default)

       nic
	   The base network interface on which the IP address will be brought online. If left empty, the script will try and determine this from
	   the routing table.

	   Do NOT specify an alias interface in the form eth0:1 or anything here; rather, specify the base interface only. If you want a label,
	   see the iflabel parameter.

	   Prerequisite:

	   There must be at least one static IP address, which is not managed by the cluster, assigned to the network interface. If you can not
	   assign any static IP address on the interface, modify this kernel parameter:

	   sysctl -w net.ipv4.conf.all.promote_secondaries=1 # (or per device)

	   (optional, string, no default)

       cidr_netmask
	   The netmask for the interface in CIDR format (e.g., 24 and not 255.255.255.0)

	   If unspecified, the script will also try to determine this from the routing table.

	   (optional, string, no default)

       broadcast
	   Broadcast address associated with the IP. If left empty, the script will determine this from the netmask.

	   (optional, string, no default)

       iflabel
	   You can specify an additional label for your IP address here. This label is appended to your interface name.

	   A label can be specified in nic parameter but it is deprecated. If a label is specified in nic name, this parameter has no effect.

	   (optional, string, no default)

       lvs_support
	   Enable support for LVS Direct Routing configurations. In case a IP address is stopped, only move it to the loopback device to allow the
	   local node to continue to service requests, but no longer advertise it on the network.

	   Notes for IPv6: It is not necessary to enable this option on IPv6. Instead, enable 'lvs_ipv6_addrlabel' option for LVS-DR usage on
	   IPv6.

	   (optional, boolean, default false)

       lvs_ipv6_addrlabel
	   Enable adding IPv6 address label so IPv6 traffic originating from the address's interface does not use this address as the source. This
	   is necessary for LVS-DR health checks to realservers to work. Without it, the most recently added IPv6 address (probably the address
	   added by IPaddr2) will be used as the source address for IPv6 traffic from that interface and since that address exists on loopback on
	   the realservers, the realserver response to pings/connections will never leave its loopback. See RFC3484 for the detail of the source
	   address selection.

	   See also 'lvs_ipv6_addrlabel_value' parameter.

	   (optional, boolean, default false)

       lvs_ipv6_addrlabel_value
	   Specify IPv6 address label value used when 'lvs_ipv6_addrlabel' is enabled. The value should be an unused label in the policy table
	   which is shown by 'ip addrlabel list' command. You would rarely need to change this parameter.

	   (optional, integer, default 99)

       mac
	   Set the interface MAC address explicitly. Currently only used in case of the Cluster IP Alias. Leave empty to chose automatically.

	   (optional, string, no default)

       clusterip_hash
	   Specify the hashing algorithm used for the Cluster IP functionality.

	   (optional, string, default "sourceip-sourceport")

       unique_clone_address
	   If true, add the clone ID to the supplied value of IP to create a unique address to manage

	   (optional, boolean, default false)

       arp_interval
	   Specify the interval between unsolicited ARP packets in milliseconds.

	   (optional, integer, default 200)

       arp_count
	   Number of unsolicited ARP packets to send.

	   (optional, integer, default 5)

       arp_bg
	   Whether or not to send the ARP packets in the background.

	   (optional, string, default "true")

       arp_mac
	   MAC address to send the ARP packets to.

	   You really shouldn't be touching this.

	   (optional, string, default "ffffffffffff")

       arp_sender
	   The program to send ARP packets with on start. For infiniband interfaces, default is ipoibarping. If ipoibarping is not available, set
	   this to send_arp.

	   (optional, string, no default)

       flush_routes
	   Flush the routing table on stop. This is for applications which use the cluster IP address and which run on the same physical host that
	   the IP address lives on. The Linux kernel may force that application to take a shortcut to the local loopback interface, instead of the
	   interface the address is really bound to. Under those circumstances, an application may, somewhat unexpectedly, continue to use
	   connections for some time even after the IP address is deconfigured. Set this parameter in order to immediately disable said shortcut
	   when the IP address goes away.

	   (optional, boolean, default false)
