How to Add Mediator Hosts

Perform this procedure if your configuration requires dual-string mediators.

1. Become superuser on the node that currently masters the diskset to which you intend to add mediator hosts.

2. Run the metaset(1M) command to add each node with connectivity to the diskset as a mediator host for that diskset.

   # metaset -s setname -a -m mediator-host-list

   -s setname

   Specifies the diskset name

   -a

   Adds to the diskset

   -m mediator-host-list

   Specifies the name of the node to add as a mediator host for the diskset

   See the mediator(7D) man page for details about mediator-specific options to the metaset command.

3. Check the status of mediator data.

Example—Adding Mediator Hosts

The following example adds the nodes phys-schost-1 and phys-schost-2 as mediator hosts for the diskset dg-schost-1. Both commands are run from the node phys-schost-1.

# metaset -s dg-schost-1 -a -m phys-schost-1
# metaset -s dg-schost-1 -a -m phys-schost-2
