When you activate a protection group using the command in this procedure, application resource groups in the protection group are also brought online. For details about how the -e (scope) option affects resource groups in the protection group, see the geopg(1M) man page.
Log in to a cluster node.
You must be assigned the Geo Management RBAC rights profile to complete this procedure. For more information about RBAC, see Sun Cluster Geographic Edition Software and RBAC in Sun Cluster Geographic Edition System Administration Guide.
Activate the protection group.
# geopg start -e scope [-n] protectiongroupname |
Specifies the scope of the command.
If the scope is local, then the command operates on the local cluster only. If the scope is global, the command operates on both clusters that deploy the protection group.
The property values global and local are not case sensitive.
Prevents the start of data replication at protection group startup.
If you omit this option, the data replication subsystem starts at the same time as the protection group.
Specifies the name of the protection group.
The geopg start command uses the scswitch -Z -g resourcegrouplist command to bring resource groups and resources online. For more information about using this command, see the scswitch(1M) man page.
In this example, the Sun Cluster Geographic Edition software starts data replication of an EMC Symmetrix Remote Data Facilitydevice group.
First, the EMC Symmetrix Remote Data Facility protection group is created.
phys-paris-1# geopg create -s paris-newyork-ps -o primary -d srdf srdfpg |
The device group devgroup1 is added to the protection group.
phys-paris-1# geopg add-device-group devgroup1 srdfpg |
The current RDF pair state of an EMC Symmetrix Remote Data Facility device group, devgroup1, is returned in the output of the symrdf query command as follows:
phys-paris-1# symrdf -g devgroup1 query Device Group (DG) Name : devgroup1 DG's Type : RDF1 DG's Symmetrix ID : 000187401215 Source (R1) View Target (R2) View MODES -------------------------------- ------------------------ ----- ------------ ST LI ST Standard A N A Logical T R1 Inv R2 Inv K T R1 Inv R2 Inv RDF Pair Device Dev E Tracks Tracks S Dev E Tracks Tracks MDA STATE -------------------------------- -- ------------------------ ----- ------------ DEV001 00E4 RW 0 36 NR 00E4 RW 36 0 S.. Split DEV002 00E5 RW 0 36 NR 00E5 RW 36 0 S.. Split DEV003 00E6 RW 0 36 NR 00E6 RW 36 0 S.. Split |
The aggregate device group state is Split.
Next, the protection group, srdfpg, is activated by using the geopg start command.
phys-paris-1# geopg start -e local srdfpg |
The Sun Cluster Geographic Edition software runs the symrdf -g devgroup1 establish command at the data replication level. If the command is successful, the state of devgroup1 is returned in the output of the symrdf query command as follows:
phys-paris-1# symrdf -g devgroup1 query Device Group (DG) Name : devgroup1 DG's Type : RDF1 DG's Symmetrix ID : 000187401215 Source (R1) View Target (R2) View MODES -------------------------------- ------------------------ ----- ------------ ST LI ST Standard A N A Logical T R1 Inv R2 Inv K T R1 Inv R2 Inv RDF Pair Device Dev E Tracks Tracks S Dev E Tracks Tracks MDA STATE -------------------------------- -- ------------------------ ----- ------------ DEV001 00E4 RW 0 0 RW 00E4 WD 0 0 S.. Synchronized DEV002 00E5 RW 0 0 RW 00E5 WD 0 0 S.. Synchronized DEV003 00E6 RW 0 0 RW 00E6 WD 0 0 S.. Synchronized |
This example activates a protection group globally.
# geopg start -e global srdfpg |
The protection group, srdfpg, is activated on both clusters where the protection group is configured. The application resource groups in srdfpg are brought online on the primary cluster.
This example activates a protection group on a local cluster only. This local cluster might be a primary cluster or a secondary cluster, depending on the role of the cluster.
# geopg start -e local srdfpg |
If the local cluster is the primary cluster, the resource groups in srdfpg also brought online on that cluster.
