Monitoring the Runtime Status of the Geographic Edition Software
You can display the runtime status of the local Geographic Edition enabled cluster
by using the geoadm status command. When you run this command, it displays output
that is organized in the following sections:
-
Cluster – Provides the name of the local cluster
-
Partnership – Provides information all partnership, including the name of the partner cluster, the synchronization state, the local heartbeats, and the local heartbeat plug-in
-
Protection group – Provides information about the status of protection groups, including information about the local cluster and the remote cluster
-
Pending operations – Provides status information about any ongoing transaction processes
You must be assigned the Basic Solaris User RBAC rights profile to
run the geoadm status command. For more information about RBAC, see Geographic Edition Software and RBAC.
For example, an administrator runs the geoadm status command on cluster-paris and the following
information is displayed:
phys-paris-1# geoadm status
Cluster: cluster-paris
Partnership "paris-newyork-ps": OK
Partner clusters : cluster-newyork
Synchronization : OK
ICRM Connection : OK
Heartbeat "paris-to-newyork" monitoring "cluster-newyork": OK
Heartbeat plug-in "ping_plugin" : Inactive
Heartbeat plug-in "tcp_udp_plugin" : OK
Protection group "tcpg" : OK
Partnership : "paris-newyork-ps"
Synchronization : OK
Cluster cluster-paris : OK
Role : Primary
PG activation state : Activated
Configuration : OK
Data replication : OK
Resource groups : OK
Cluster cluster-newyork : OK
Role : Secondary
PG activation state : Activated
Configuration : OK
Data replication : OK
Resource groups : OK
Pending Operations
Protection Group : "tcpg"
Operation : start
The information displayed shows that the protection group, tcpg, is activated on both
the primary cluster, cluster-paris, and the secondary cluster, cluster-newyork. Data is replicating between the
partner clusters and both partners are synchronized.
The following table describes the meaning of the status values.
Table 8-1 Status Value Descriptions
|
|
Partnership |
OK –
The partners are connected. Error – The connection between the partner clusters is lost. Degraded
– The partnership has been successfully created but a connection with the partner
cluster has not yet been established. This status value occurs when the partnership
has been created and the partner cluster has not been configured. |
Synchronization |
OK – The
configuration information is synchronized between partner clusters. Error – The configuration information differs between the
partner clusters. You need to resynchronize the partnership for a partnership synchronization error,
or resynchronize the protection group, for a protection group synchronization error. For information about
resynchronizing a partnership, see Resynchronizing a Partnership. For information about resynchronizing a protection group, see
the following data replication guide:
Mismatch – Configuration information has been created separately on the
clusters. The configuration information must be replaced by a copy of the configuration
information from the partner cluster. You can synchronize the protection group configuration by
using the geopg get command. Unknown – Information is not accessible because the partners are
disconnected or because some components of the protection group cannot be reached. |
ICRM Connection |
OK –
The Intercluster Resource Management (ICRM) module is running properly. Error – The ICRM module
on the local cluster is unable to communicate with the ICRM module on
the remote cluster. |
Heartbeat |
OK – Heartbeat checks are running and the partner cluster
responds within the specified timeout and retry periods. Offline – Heartbeat checks are
not running. Error – Heartbeat checks are running but the partner is not responding
and retries have timed out. Degraded – Heartbeat checks are running but one of
the primary plug-ins is degraded or not running. |
Heartbeat plug-in |
OK – Responses are being
received from the partner. Inactive – Plug-in is not in use but is a
standby for retrying to contact the partner if the other plug-ins obtain no
response. No-Response – Partner cluster is not responding. |
Protection group (overall protection group state) |
OK –
The synchronization state is OK and the state of the protection group on
each cluster is OK. Degraded – The synchronization state is OK. The state
of the protection group is Degraded on either one or both clusters in
the partnership. Unknown – The synchronization state or the state of the protection group
on one or both clusters is unavailable. The protection group can be online
or offline. Error – The synchronization state or the state of the protection group
on one or both clusters is in Error. The protection group can be
online or offline. |
Protection group > Cluster (state of protection group on each cluster) |
OK
– The state of all the protection group components, such as configuration data,
data replication, or resource groups, is OK, NONE, or N/A on the cluster. Degraded –
The state of one or more of the protection group components is in
the Degraded state on the cluster. Unknown – The state of some components of
the protection group, such as configuration data, data replication, or resource groups, is unavailable. Error
– The state of some components of the protection group, such as configuration
data, data replication, or resource groups, is in Error. |
Protection group > Cluster > Role |
Primary
– The cluster is the Primary for this protection group. Secondary – The cluster
is the Secondary for this protection group. Unknown – Information is not accessible because the
partners are disconnected or because some components of the protection group cannot be
reached. |
Protection group > Cluster > PG activation state |
Activated – The protection group is activated. Deactivated –
The protection group is deactivated. Unknown – Information is not accessible because the partners
are disconnected or because some components of the protection group cannot be reached. |
Protection group
> Cluster > Configuration |
OK – Protection group configuration has been validated without errors
on the cluster. Error – Protection group configuration validation resulted in errors on the
cluster. You need to revalidate the protection group. For information about validating a
protection group, see the following data replication guide:
Unknown – Information is not accessible
because the partners are disconnected or because some components of the protection group cannot
be reached. |
Protection group > Cluster > Data replication |
None – Data replication is not configured. OK
– Data replication is running and data is synchronized with the partner cluster
when the protection group is activated. Replication is suspended when the protection group
is deactivated. This state represents data replication on this cluster and does not
reflect the overall state of data replication. This state is mapped from the
corresponding state in the data replication subsystem. Degraded – Data is not replicated and
not synchronized with the partner cluster when the protection group is activated. New
writes will succeed but not be replicated. This state represents data replication on this
cluster and does not reflect the overall state of data replication. This state
is mapped from the corresponding state in the data replication subsystem. Error – Data
replication from the primary cluster to the secondary cluster is in error if
the data replication subsystem reports an error or if data replication is not
suspended when the protection group is deactivated. This state represents data replication on
this cluster and does not reflect the overall state of data replication. This
state is mapped from the corresponding state in the data replication subsystem. Unknown –
Information is not accessible because the partners are disconnected or because some components
of the protection group cannot be reached. N/A – The data replication state of
the protection group could not be mapped. Data replication is in a valid
state on its own but in an Error state for the protection group.
This state is available only if you are using Availability Suite data replication. |
Protection group
> Cluster > Resource groups |
None – No resource group is protected by this protection
group. OK – If the cluster has the Primary role, all resource groups are
online when the protection group is activated or unmanaged when the protection group
is deactivated. If the cluster has the Secondary role, all resource groups
are unmanaged. Error – If the cluster has the Primary role, not all resource
groups are online when the protection group is activated or unmanaged when the
protection group is deactivated. If the cluster has the Secondary role, not all
resource groups are unmanaged. Unknown – Information is not accessible because the partners are
disconnected or because some components of the protection group cannot be reached. |
