Selecting a Failure Detection Method

Probe-based failure detection can operate either by using a transitive method that does not use test addresses or by configuring test addresses.

Also, if the NIC driver supports it, link-based failure detection is always enabled automatically. You cannot disable link-based failure detection if this method is supported by the NIC driver. However, you can select which type of probe-based failure detection to implement.

Before selecting a probe-based detection method, make sure that your probe targets meet the requirements that are listed in Requirements for Choosing Targets for Probe-based Failure Detection.

To use transitive probing, follow these steps:

  1. Enable the IPMP property transitive-probing by using SMF commands.

    $ svccfg -s svc:/network/ipmp setprop config/transitive-probing=true
    $ svcadm refresh  svc:/network/ipmp:default

    See the in.mpathd(8) man page.

  2. Remove any existing test addresses that have been configured for the IPMP group.

    $ ipadm delete-addr address addrobj

    addrobj must refer to an underlying interface that hosts a test address.

To use test addresses to probe for failure, assign test addresses to the underlying interfaces of the IPMP group.

$ ipadm create-addr -a address under-interface

address can be in CIDR notation and under-interface is an underlying interface of the IPMP group.
