● The Threshold and Period values determine the number of times
cluster service will attempt to restart the failed resource within a
specified period of time before moving the group to another node.
● "Looks Alive" poll interval—This setting specifies how often the resource is
polled to determine whether it is still running on the active node. You can
choose a value from the resource type, or you can specify your own value.
● "Is Alive" poll interval—This setting designates how often the possible
owners are polled to determine whether the specified disk on each node can
be written to and read from. You can choose a value from the resource type,
or you can specify your own value.
● Pending timeout—This value determines how long the resource is allowed
to remain in a pending state before it fails. If the resource takes longer than
the time specified to be brought online or taken offline, the resource fails.
For more information on the Advanced Settings options, see your Windows
documentation.
4. Connection parameters—This tab controls disk replication, network routing, and
orphan files for GeoCluster.
● Disk to replicate—The volume to replicate
● Network to route Double-Take mirroring and replication traffic over—
The network to use for Storage Mirroring Recover mirroring and replication
traffic. If you do not have multiple networks established, you will only be able
to select the one network that does exist. If you do not select a network,
GeoCluster will use DNS to determine a network route to use.
Ideally, the networks used for various traffic should be separated. This is
dependent on the number of networks that you established when you created
the cluster and the priority assigned to each network. For example, if you
have two network routes, separate GeoCluster and your public traffic. If you
have three routes, separate the public traffic and then separate GeoCluster
from the cluster heartbeat.
Modifications to either of the first two settings will not take effect until the next
time the resource is brought online.
● Interval to check unresponsive nodes—The frequency to determine how
often an unresponsive node is checked to see if a Storage Mirroring Recover
connection can be made
● Delay connection until resources dependent on this one are online—
This option allows you to delay a Storage Mirroring Recover connection until
any resources that have the GeoCluster Replicated Disk resource as a
dependency are online. By ensuring that all resources that are dependent on
the GeoCluster Replicated disk resource are online before starting the
