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
connection, the chance of a conflict occurring because application resources
are attempting to open files exclusively while Storage Mirroring Recover is
mirroring those files is removed.
l
Enable orphans—An orphan is a file that exists in the target location but is
not in the source location. You can enable the resource to Move orphans or
Delete orphans during a mirror. If you choose to move orphan files, specify
the location where you want to move them. You should not select the system
volume for the orphan files because it could impact the stability of the cluster
service.
5. No other settings are required for the GeoCluster Replicated Disk resource,
although there are
available. Click OK to save the GeoCluster
Replicated Disk configuration changes that you made.
6. If you are using Hyper-V, you have several additional configuration steps.
a. Take the virtual machine’s configuration resource offline by right-clicking on it
and selecting Take this resource offline.
b. Modify the virtual machine’s configuration resource and specify the
GeoCluster Replicated Disk resource (not the GRD Status resource) as a
dependency.
c. Modify the virtual machine resource (the parent of the virtual machine
configuration resource) and specify the GeoCluster Replicated Disk resource
(not the GRD Status resource) as a dependency.
d. From a command prompt, execute the following command, substituting the
name of your GeoCluster Replicated Disk resource.
cluster res "New Geocluster Replicated Disk" /priv sourcefailoverdelay=15
The GeoCluster Replicated Disk will mirror and replicate the virtual machine
data to the other cluster nodes.
7. To control the resource, you can bring it online and take it offline. Neither of these
actions trigger failover. They just control the activity of the resource.
