Suspending A Remote Replication Group
Use the asyncRemoteReplicationGroup command to stop data transfer between a primary virtual disk and a
secondary virtual disk in a replication relationship without disabling the replication relationship. Suspending a
replication relationship group lets you control when the data on the primary virtual disk and data on the secondary
virtual disk are synchronized. Suspending a replication relationship group helps to reduce any performance impact to
the host application that might occur while any changed data on the primary virtual disk is copied to the secondary
virtual disk.
When a replication relationship is in a suspended state, the primary virtual disk does not make any attempt to contact
the secondary virtual disk. Any writes to the primary virtual disk are persistently logged in the replication repository
virtual disks. After the replication relationship resumes, any data that is written to the primary virtual disk is
automatically written to the secondary virtual disk. Only the modified data blocks on the primary virtual disk are written
to the secondary virtual disk. Full synchronization is not required.
This example shows the suspend remoteReplicationGroup command:
suspend asyncRemoteReplicationGroup ["asyncRemoteReplicationGroupName"];
The replication relationship group remains suspended until you use the resume
asyncRemoteReplicationGroup command to restart synchronization activities.
This example shows the resume remoteReplicationGroup command:
resume asyncRemoteReplicationGroup ["asyncRemoteReplicationGroupName"];
Deleting A Remote Replication Group
Use the delete asyncRemoteReplicationGroup command to delete one or more replication groups from the
local or remote storage array. The replication group you are attempting to delete must be empty (contain no virtual disks
or replicated pairs) before running this command.
This example shows the delete asyncRemoteReplicationGroup command:
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c delete asyncRemoteReplicationGroup["replication_group_name"];
To delete all replication groups from the local and remote storage arrays, use the delete
allAsyncRemoteReplicationGroups command.
To delete selected replication groups, separate group names with "":
delete asyncRemoteReplicationGroups ["name1""name2"];
Removing A Virtual Disk Or Repository Virtual Disk From A Remote
Replication Group
Use the remove virtualDisk command to remove either a member virtual disk or repository virtual disk from an
existing replication group. This command can only be run on the local storage array containing the replication group
affected by the command.
The command shown below removes
diskname from the replication group named groupname . Using the optional
deleteRepositoryMembers parameter with a value of TRUE also delete the repository virtual disk members:
remove virtualDisk ["diskname"]
asyncRemoteReplicationGroup="groupname"
deleteRepositoryMembers=TRUE;
