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 one of the following data replication guides:
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 one of
the following data replication guides:
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 Sun StorageTek 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. |
