c:\...\...\client>smcli 123.45.67.89 -c “activate storageSubsystem f
eature=remoteMirror repositoryRAIDLevel=5 repositoryDriveCount=5
driveType=fibre;”
The command in this example creates a new mirror repository logical drive by using five
software
selected disk drives for the mirror repository logical drive. The mirror repository logical drive
has a RAID level of 5. The type of drive for the mirror repository logical drive is Fibre Channel.
This example shows how to use the command in a script file:
activate storageSubsystem feature=remoteMirror
repositoryRAIDLevel=5 repositoryDriveCount=5
driveType=fibre;
Determining Candidates for a Remote-Mirror Pair
All of the logical drives and disk drives on the remote storage subsystem might not be available for use
as secondary logical drives. To determine which logical drives on a remote storage subsystem that you
can use as candidates for secondary logical drives, use the
show remoteMirror candidates
command. This
command returns a list of the logical drives that you can use when creating a remote mirror.
The command takes this form:
c:\...\...\client>smcli 123.45.67.89 -c “show
remoteMirror candidates primary=\“
logicalDriveName \”
remoteStorageSubsystemName=\“ storageSubsystemName \”;”
where logicalDriveName is the name of the logical drive that you want to use for the primary logical
drive, and StorageSubsystemName is the remote storage subsystem that contains possible candidates for the
secondary logical drive. Enclose both the logical drive name and the storage subsystem name in double
quotation marks (“ ”).
Creating a Remote Mirror Pair
When you create a new remote mirror, you must define which logical drives that you want to use for the
primary (local) logical drive and the secondary (remote) logical drive. You define the primary logical
drive by the name of the logical drive. You define the secondary logical drive by name with either the
name or the World-Wide Identifier (WWID) of the storage subsystem on which the secondary logical
drive resides. The primary logical drive name, the secondary logical drive name, and the remote storage
subsystem 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 remoteMirror primary=“ primaryLogicalDriveName ”
secondary=“ secondaryLogicalDriveName ”
(remoteStorageSubsystemName=“ storageSubsystemName ” |
remoteStorageSubsystemWwn=“ wwID ”) remotePassword= password
syncPriority=(highest | high | medium | low | lowest)
writeOrder=(preserved | notPreserved)
writeMode=(synchronous | asynchronous)
Note: You can use the optional parameters as needed to help define your configuration.
This example shows the
create remoteMirror
command:
c:\...\...\client>smcli 123.45.67.89 -c “create
remoteMirror primary=\”Jan_04_Account\”
secondary=\”Jan_04_Account_B\” remoteStorageSubsystemName=\”Tabor\”
remotePassword=\”jdw2ga05\” syncPriority=highest
writeMode=synchronous;”
