GeoCluster Replicated Disk properties on Windows 2003

There are six properties tabs for the GeoCluster Replicated Disk resource on Windows
2003.

1. General—This tab identifies the Name and Description of the resource and the

Possible Owners. If you change the name of the resource, the replication set
name will not change until the next time the resource is brought online. The
GeoCluster Replicated Disk resource must have at least two possible owners to
function properly. Modifying the Possible Owners list will cause one of the
following actions to occur.

l

If you add additional Possible Owners, the GeoCluster Replicated Disk
resource will connect the resource’s replication set to the new owners and
begin a mirror to each.

l

If you remove Possible Owners, the GeoCluster Replicated Disk resource
will disconnect the resource’s replication set from each owner removed.

2. Dependencies—By default, the GeoCluster Replicated Disk resource is not

dependent on any other resources.

3. Advanced settings—This tab controls how and when MSCS handles a failure of

the resource.

l

Do not restart—Select this option if you do not want cluster service to restart
the resource if it fails.

l

Restart—Select this option if you want cluster service to restart the resource
if it fails.

l

Enable Affect the group if you want a failure of this resource to move
the group to another node. If you disable this option, cluster service still
attempts to restart the resource using the Threshold and Period
values, but the failure of the resource will not cause the group to move
to another node.

l

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.

l

"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.

l

"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.

l

Pending timeout—This value determines how long the resource is allowed
