Provider

HP-UX Logical Volume Manager CIM Provider

Provider Overview Web Based Enterprise Management is an industry wide initiative to unify the management of system,

networks and applications across multiple and diverse vendor environments.

Description The LVM provider makes available the Logical Volume Manager information. The LVM provider instruments

the HPUX_VolumeGroup, HPUX_PhysicalVolume, HPUX_LogicalVolume and HPUX_PhysicalVolumeGroup

classes and also associations between these classes.

This provider is for use by WBEM clients as part of making available the various attributes of the LVM

subsystem. The current implementation is for HP-UX only and the provider is an Instance Provider (read-only

properties).

Requirements Pre-requisite:

The provider requires HP WBEM Services A.02.05 for HP-UX 11i v1.

Comments This provider makes a security check to ensure the CIMOM user has rights to access LVM information. The

provider uses system utilities lvdisplay, pvdisplay and vgdisplay to gather data about HPUX_LogicalVolume,

HPUX_PhysicalVolume and HPUX_VolumeGroup classes. The logged user must have permissions to execute

these utilities otherwise the execution fails with CIM_ERR_FAILED.

Release history Initial release with HP WBEM Services A.02.05 for HP-UX 11i v1.

Supported managed

resources

The Logical Volume Manager subsystem.

Supported OS

HP-UX 11i v1

Special Requirements &

Dependencies

WBEM Services must be installed, configured and running on the managed system to which this provider is

registered for use.

Setting up this

provider

The LVM provider is available as an ISU for HP-UX 11i v1.

Installing this provider This LVM provider installs the following files/directories on the system:

• Schema MOF file: LVMProvider.mof (in /opt/lvmprovider/mof)

• Provider registration MOF file: LVMProviderR.mof (in /opt/lvmprovider/mof)

• Provider module executable:

libHPUXLVMProviderModule.1 (in /opt/lvmprovider/lib, and is the target of the

/opt/wbem/providers/lib/libHPUXLVMProviderModule.sl symbolic link)

The HP-UX LVM Provider is registered to support the "root/cimv2" namespace as an instance provider.

There are no special installation instructions; the provider will be installed by default with HP-UX 11i v1

0612 OE-UR and AR.

Configuring this provider This provider does not accept specific configuration adjustments (beyond standard WBEM support). Using this provider schema supported by this provider This provider supports the HPUX_LogicalVolume, HPUX_PhysicalVolume, HPUX_PhysicalVolumeGroup, HPUX_VolumeGroup classes and associations between them. Tables 1 to 9 describe the properties and methods supported by the provider. Table 1: HPUX_LogicalVolume properties Table 1 describes the properties of the HPUX_LogicalVolume class.
PAGE 3
string Description Inherited from CIM_ManagedElement HP-UX: Returns the string “Logical Volume DeviceID”. boolean IsBasedOnUnderlyingRedundancy Inherited from CIM_StorageExtent HP-UX: Returns true if MirrorCopyNumber > 1, false otherwise. uint32 IOTimeout Local to HPUX_LogicalVolume HP-UX: Returns the IO Timeout value of the logical volume in seconds. IOTimeout is obtained from lvdisplay command, “IO Timeout” field.
PAGE 4
if LVStatus is none of the above then Status is “Unknown” LVStatus is obtained from lvdisplay command, “LV Status” field. uint32 StripeSize Local to HPUX_LogicalVolume HP-UX: Returns size of stripes for the logical volume, in kilobytes. Obtained from lvdisplay command, “Stripe Size” field. Table 2: HPUX_PhysicalVolume properties Table 2 describes the properties of the HPUX_PhysicalVolume class. It has three columns.
PAGE 5
uint32 IOTimeout Local to HPUX_PhysicalVolume HP-UX: Returns the IO Timeout value of the physical volume in seconds. IOTimeout is obtained from pvdisplay command, “IO Timeout” field. uint32 NumberAllocatedPEs Local to HPUX_PhysicalVolume HP-UX: Returns size of the allocated physical volume in number of physical extents. Obtained from pvdisplay command, “Allocated PE” field.
PAGE 6
Table 3: HPUX_PhysicalVolumeGroup properties Table 3 describes the properties of the HPUX_PhysicalVolumeGroup class. It has three columns. The first is the property name (including type and units), the second is the property inheritance (indicating which class or super class defines the property), and the third is the property’s description and value. Each row describes a property.
PAGE 7
from vgdisplay command, “Max PE per PV” field. uint32 NumberOfActiveLVs Local to HPUX_VolumeGroup HP-UX: Returns the number of current active logical volumes in the volume group. Obtained from vgdisplay command, “Open LV” field. uint32 NumberOfActivePVs Local to HPUX_VolumeGroup HP-UX: Returns the number of current active physical volumes in the volume group uint32 NumberOfDefinedLVs Local to HPUX_VolumeGroup HP-UX: Returns the number of current defined logical volumes in the volume group.
PAGE 8
provider associations. Tables 5 to 8 describe the associations supported by the provider. Table5: HPUX_LVBasedOnPV Association Properties - HPUX_LVBasedOnPV is an association describing the Physical Volumes used in creating a Logical Volume. Table 5 describes the properties of the HPUX_LVBasedOnPV association class. It has three columns.
PAGE 9
HPUX_PhysicalVolume REF Member [key] Local to HPUX_PVInPVG HP-UX: Returns the lower level StorageExtent. HPUX_PhysicalVolumeGroup REF Collection [key] Local to HPUX_PVInPVG HP-UX: Returns the higher level StorageExtent. Table9: Intrinsic methods for all classes Table 9 describes the intrinsic methods supported by this provide for all classes. It has three columns.
