You can create a RAID array using local drives.
To create a RAID array, follow these steps:
-
Obtain the reference (CIMObjectPath) of an IBMTSSVC_StorageConfigurationService
instance that is associated with the IBMTSSVC_Cluster in which you
will create the new RAID array using one of the following
two methods:
- Obtain the reference of the IBMTSSVC_StorageConfigurationService
instance directly. There is only one instance obtained by enumeration
because CIMOM is embedded in the clustered system.
- Obtain the reference of the IBMTSSVC_StorageConfigurationService
instance by traversing the IBMTSSVC_HostedStorageConfigurationService
association.
-
Invoke the IBMTSSVC_StorageConfigurationService CreateOrModifyElementFromElements
method.
You must specify the following parameters:
- The InElements [] parameter with a list of IBMTSSVC_DiskDriveExtent
instances. The Extent [] parameter is a string array that contains
the representation of the CIMObjectPath to an IBMTSSVC_ DiskDriveExtent.
Only a disk drive with role of candidate is available for use in
an array. To change the role of a disk drive, complete the following
steps:
- Obtain the reference (CIMObjectPath) of an IBMTSSVC_StorageConfigurationService
instance that is associated with the IBMTSSVC_Cluster
- Invoke the IBMTSSVC_StorageConfigurationService ChangeDriveRole
method. You must specify the DiskDrive parameter with the reference
of the IBMTSSVC_DiskDrive, and set Use parameter to 1.
- StoragePool parameter with an instance of IBMTSSVC_ConcreteStoragePool, which
identifies the StoragePool to add the created RAID array
to.
- Goal parameter with an instance of IBMTSSVC_RAIDSetting, which
contains the RAID-level information.
You can also specify the StripSize, WriteVerify, and
SpareGoal. Also see the BlockServices.mof file
for more details. To view the complete Managed Object Format (MOF)
