Use the Viewing Metro and Global Mirror Properties panel
in the SAN Volume Controller Console to
view Metro Mirror and Global Mirror properties related to the cluster.
Introduction
This
panel displays two sets of properties that are related to cluster
partnerships. The first table contains properties that pertain to
all the partnerships that are defined on the selected cluster. The
second table displays properties for each of the clusters that are
defined in partnerships with the selected cluster.
Attributes
The
following properties pertain to the Global Mirror partnerships:
- Link Tolerance
- Displays the length of time that the primary response time remains
impacted before relationships are suspended. Valid values are 0 -
86400 seconds. A value of zero disables this feature. The default
value is 300 seconds.
- InterCluster Delay Simulation
- Displays the amount of time to delay I/O writes to the intercluster
secondary VDisk. Valid values are 0 - 100 milliseconds. A value
of zero disables this feature. The default value is zero.
- IntraCluster Delay Simulation
- Displays the amount of time to delay I/O writes to the intracluster
secondary VDisk. Valid values are 0 - 100 milliseconds. A value
of zero disables this feature. The default value is zero.
Attributes
The following attributes are displayed for the selected
cluster that is defined in the partnership:
- Cluster Name
- Displays the name of the selected cluster.
- IP address (IPv4)
- Displays the IPv4 IP address of the local or remote partner cluster.
- IP address (IPv6)
- Displays the IPv6 IP address of the local or remote partner cluster.
- Location
- Displays whether the selected cluster is a local or remote partner
cluster.
- State
- Displays the current state of the partnership. The following values
are possible:
- Partially Configured
- Indicates that only one cluster partner is defined from a local
or remote cluster to the displayed cluster and is started. For the
displayed cluster to be configured fully and to complete the partnership,
you must define the cluster partnership from the cluster that is displayed
to the corresponding local or remote cluster. You can do this by issuing
the mkpartnership command on the local and remote cluster that
are in the partnership, or by using the SAN Volume Controller Console to
create a partnership on both the local and remote clusters.
- Fully Configured
- Indicates that the partnership is defined on the local and remote
clusters and is started.
- Remote Not Present
- Indicates that the remote cluster is not present to the partnership.
- Partially Configured (Local Stopped)
- Indicates that the local cluster is only defined to remote cluster
and the local cluster is stopped.
- Fully Configured (Local Stopped)
- Indicates that a partnership is defined on both the local and
remote clusters and the remote cluster is present, but the local cluster
is stopped.
- Fully Configured (Remote Stopped)
- Indicates that a partnership is defined on both the local and
remote clusters and the remote cluster is present, but the remote
cluster is stopped.
- Fully Configured (Local Excluded)
- Indicates that a partnership is defined between a local and remote
cluster; however, the local cluster has been excluded. Usually this
state occurs when the fabric link between the two clusters has been
compromised by too many fabric errors or slow response times of the
cluster partnership. Check the error log for 1720 errors by selecting to resolve these errors.
- Fully Configured (Remote Excluded)
- Indicates that a partnership is defined between a local and remote
cluster; however, the remote cluster has been excluded. Usually this
state occurs when the fabric link between the two clusters has been
compromised by too many fabric errors or slow response times of the
cluster partnership. Check the error log for 1720 errors by selecting to resolve these errors.
- Fully Configured (Remote Exceeded)
- Indicates that a partnership is defined between a local and remote
cluster and the remote is available; however, the remote cluster exceeds
the number of allowed clusters within a cluster network. The maximum
of four clusters can be defined in a network. If the number of clusters
exceeds that limit, SAN Volume Controller determines
the inactive cluster or clusters by sorting all the clusters by their
unique identifier in numerical order. The inactive cluster partner
which is not in the top four of the cluster unique identifiers displays Fully
Configured (Remote Exceeded).
- Bandwidth (MBps)
- Displays the bandwidth that was specified,
shown in megabytes per second (MBps).
