creates a new disk group. For this command to work, you must have physical disks in the storage array that are not assigned to a disk group. activate storageArray feature=remoteReplication repositoryRAIDLevel=(1 | 5 | 6) repositoryPhysicalDiskCount=numberOfPhysicalDisks [physicalDiskType=(SAS)] [enclosureLossProtect=(TRUE | FALSE)] This example shows a command in which you specify the number of physical disks: c:\...\smX\client>smcli 123.45.67.88 123.45.67.89 -c "activate storageArray feature=remoteReplication repositoryRAIDLevel=5 repositoryPhysicalDiskCount=5 physicalDiskType=SAS;" The command in this example creates a new replication repository virtual disk by using five software-selected physical disks for the replication repository virtual disk. The replication repository virtual disk has RAID Level 5. The type of physical disk for the replication repository virtual disk is SAS. This example shows how to use the command in a script file: activate storageArray feature=remoteReplication repositoryRAIDLevel=5 repositoryCount=5 physicalDiskType=SAS; Determining Candidates For A Remote Replicated Pair All of the virtual disks and physical disks on the remote storage array might not be available for use as secondary virtual disks. To determine which virtual disks on a remote storage array that you can use as candidates for secondary virtual disks, use the show remoteReplication candidates command. This command returns a list of the virtual disks that you can use when creating a remote replication. The command takes this form: c:\...\smX\client>smcli 123.45.67.88 123.45.67.89 -c "show remoteReplication candidates primary= \"virtualDiskName\" remoteStorageArrayName=\"storageArrayName\";" where virtualDiskName is the name of the virtual disk that you want to use for the primary virtual disk, and storageArrayName is the remote storage array that contains possible candidates for the secondary virtual disk. Enclose both the virtual disk name and the storage array name in double quotation marks (" "). Creating A Remote Replicated Pair When you create a new remote replication, you must define which virtual disks that you want to use for the primary (local) virtual disk and the secondary (remote) virtual disk. You define the primary virtual disk by the name of the virtual disk. You define the secondary virtual disk by name with either the name or the World Wide Identifier (WWID) of the storage array on which the secondary virtual disk resides. The primary virtual disk name, the secondary virtual disk name, and the remote storage array name (or WWID) are the minimum information that you need to provide. Using this command, you can also define synchronization priority, write order, and write mode. The command takes this form: create remoteReplication primary= "primaryVirtualDiskName" secondary="secondaryVirtualDiskName" (remoteStorageArrayName="storageArrayName" | remoteStorageArrayWwn="wwID") remotePassword=password syncPriority=(highest | high | medium | low | lowest) 73

creates a new disk group. For this command to work, you must have physical disks in the storage array that are not
assigned to a disk group.
activate storageArray feature=remoteReplication
repositoryRAIDLevel=(1 | 5 | 6)
repositoryPhysicalDiskCount=numberOfPhysicalDisks
[physicalDiskType=(SAS)]
[enclosureLossProtect=(TRUE | FALSE)]
This example shows a command in which you specify the number of physical disks:
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “activate storageArray feature=remoteReplication
repositoryRAIDLevel=5 repositoryPhysicalDiskCount=5
physicalDiskType=SAS;”
The command in this example creates a new replication repository virtual disk by using five software-selected physical
disks for the replication repository virtual disk. The replication repository virtual disk has RAID Level 5. The type of
physical disk for the replication repository virtual disk is SAS.
This example shows how to use the command in a script file:
activate storageArray feature=remoteReplication
repositoryRAIDLevel=5 repositoryCount=5
physicalDiskType=SAS;
Determining Candidates For A Remote Replicated Pair
All of the virtual disks and physical disks on the remote storage array might not be available for use as secondary virtual
disks. To determine which virtual disks on a remote storage array that you can use as candidates for secondary virtual
disks, use the
show remoteReplication candidates
command. This command returns a list of the virtual
disks that you can use when creating a remote replication.
The command takes this form:
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “show remoteReplication candidates primary= \“virtualDiskName\”
remoteStorageArrayName=\“storageArrayName\”;”
where
virtualDiskName
is the name of the virtual disk that you want to use for the primary virtual disk, and
storageArrayName
is the remote storage array that contains possible candidates for the secondary virtual disk.
Enclose both the virtual disk name and the storage array name in double quotation marks (“ ”).
Creating A Remote Replicated Pair
When you create a new remote replication, you must define which virtual disks that you want to use for the primary
(local) virtual disk and the secondary (remote) virtual disk. You define the primary virtual disk by the name of the virtual
disk. You define the secondary virtual disk by name with either the name or the World Wide Identifier (WWID) of the
storage array on which the secondary virtual disk resides. The primary virtual disk name, the secondary virtual disk
name, and the remote storage array name (or WWID) are the minimum information that you need to provide. Using this
command, you can also define synchronization priority, write order, and write mode.
The command takes this form:
create remoteReplication primary=
“primaryVirtualDiskName”
secondary=“secondaryVirtualDiskName”
(remoteStorageArrayName=“storageArrayName” |
remoteStorageArrayWwn=“wwID”) remotePassword=password
syncPriority=(highest | high | medium | low | lowest)
