Perform this procedure if your configuration requires dual-string mediators.
phys-schost-3# metaset -s dummy-diskset-name -a -h hostname
Specifies the dummy disk set name.
Adds to the disk set.
Specifies the name of the node.
phys-schost# metaset -s setname -a -m mediator-host-list
Specifies the disk set name.
Specifies the name of the node to add as a mediator host for the disk set.
See the mediator (7D) man page for details about mediator-specific options to the metaset command.
The following example adds the nodes phys-schost-1 and phys-schost-2 as mediator hosts for the disk set dg-schost-1. If needed, repeat the command a third time for a third mediator host. All commands are run from the node that masters the disk set for which you are adding mediator hosts, in this case phys-schost-1.
phys-schost# metaset -s dg-schost-1 -a -m phys-schost-1 phys-schost# metaset -s dg-schost-1 -a -m phys-schost-2 phys-schost# metaset -s dg-schost-1 -a -m phys-schost-3
