Description: Defines storage management logging objects for recording storage subsystem events and operational history.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is SML-MIB?

SML-MIB (Storage Management Logging MIB) is a CIM-aligned storage-management MIB, seen here implemented by IBM (the ibm3584 branch corresponds to the IBM TotalStorage/System Storage 3584 tape library), for logging inventory and security-relevant events from a storage subsystem's chassis. It exposes product/chassis inventory data such as manufacturer, model, and serial number, alongside chassis security state including whether the unit is locked and whether a security breach has been detected. Its monitoring focus is squarely hardware/physical-security status of the storage enclosure, confirming the chassis lock is engaged, flagging a security breach event, and tracking the product's identifying/version information, rather than performance counters. It is explicitly versioned against a CIM (Common Information Model) schema (smlCimVersion), showing it maps SNIA/CIM storage-management concepts onto SNMP rather than defining its own object model from scratch. It is deployed on enterprise tape libraries and similar storage subsystems, here an IBM 3584, where physical chassis security and asset inventory need to be visible to a management station, and administrators consult the SML-MIB reference to correctly map these CIM-aligned objects.

IPNetwork Monitor allows you to monitor SNMP objects defined in SML-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Monitoring Examples

An admin would poll chassis-IsLocked and chassis-SecurityBreach to confirm the IBM 3584 tape library's front panel remains locked and hasn't registered a tamper event, cross-referencing chassis-SerialNumber and product-Version for asset-inventory records. A sudden change in chassis-SecurityBreach from false to true would trigger an immediate physical-security investigation.

INT chassis_SecurityBreach	1.3.6.1.4.1.2.6.182.3.4.5	INTEGER	read-only	SecurityBreach is an enumerated, integer-valued property indicating whether a physical breach of the Frame was attempted but unsuccessful (value=4) or attempted and successful (5). Also, the values, 'Unknown', 'Other' or 'No Breach', can be specified.
STR chassis_SerialNumber	1.3.6.1.4.1.2.6.182.3.4.3	DisplayString	read-only	A manufacturer-allocated number used to identify the Physical Element.

OID endOfSmlMib	1.3.6.1.4.1.2.6.182.3.10	OBJECT IDENTIFIER	not-accessible	Description here
ibm	1.3.6.1.4.1.2
ibm3584	1.3.6.1.4.1.2.6.182
ibmProd	1.3.6.1.4.1.2.6
INT mediaAccessDevice_Availability	1.3.6.1.4.1.2.6.182.3.6.2.1.5	INTEGER	read-only	The primary availability and status of the Device. (Additional status information can be specified using the AdditionalAvailability array property.) For example, the Availability property indicates that the Device is running and has full power (value=3), or is in a warning (4), test (5), degraded (10) or power save state (values 13-15 and 17). Regarding the Power Save states, these are defined as follows: Value 13 ('Power Save - Unknown') indicates that the Device is known to be in a power save mode, but its exact status in this mode is unknown; 14 ('Power Save - Low Power Mode') indicates that the Device is in a power save state but still functioning, and may exhibit degraded performance; 15 ('Power Save - Standby') describes that the Device is not functioning but could be brought to full power 'quickly'; and value 17 ('Power Save - Warning') indicates that the Device is in a warning state, though also in a power save mode.
STR mediaAccessDevice_Name	1.3.6.1.4.1.2.6.182.3.6.2.1.3	DisplayString	read-only	The Name property defines the label by which the object is known. When subclassed, the Name property can be overridden to be a Key property.
INT mediaAccessDevice_NeedsCleaning	1.3.6.1.4.1.2.6.182.3.6.2.1.6	INTEGER	read-only	Boolean indicating that the MediaAccessDevice needs cleaning. Whether manual or automatic cleaning is possible is indicated in the Capabilities array property.
STR mediaAccessDevice_Status	1.3.6.1.4.1.2.6.182.3.6.2.1.4	DisplayString	read-only	A string indicating the current status of the object. Various operational and non-operational statuses are defined. This property is deprecated in lieu of OperationalStatus, which includes the same semantics in its enumeration. This change is made for three reasons: 1) Status is more correctly defined as an array property. This overcomes the limitation of describing status via a single value, when it is really a multi-valued property (for example, an element may be OK AND Stopped. 2) A MaxLen of 10 is too restrictive and leads to unclear enumerated values. And, 3) The change to a uint16 data type was discussed when CIM V2.0 was defined. However, existing V1.0 implementations used the string property and did not want to modify their code. Therefore, Status was grandfathered into the Schema. Use of the Deprecated qualifier allows the maintenance of the existing property, but also permits an improved definition using OperationalStatus.
mediaAccessDeviceEntry	1.3.6.1.4.1.2.6.182.3.6.2.1		not-accessible	Each entry in the table contains information about a MediaAccessDevice that is present in the library.
mediaAccessDeviceGroup	1.3.6.1.4.1.2.6.182.3.6
NUM mediaAccessDeviceIndex	1.3.6.1.4.1.2.6.182.3.6.2.1.1	UINT32	read-only	The current index value for the MediaAccessDevice.
INT mediaAccessDeviceObjectType	1.3.6.1.4.1.2.6.182.3.6.2.1.2	INTEGER	read-only	In the 2.7 CIM Schema a Type property is no longer associated with MediaAccessDevice. However, it can be used here to specify the type of drive that is present.
mediaAccessDeviceTable	1.3.6.1.4.1.2.6.182.3.6.2		not-accessible	A MediaAccessDevice represents the ability to access one or more media and use this media to store and retrieve data.
INT numberOfMediaAccessDevices	1.3.6.1.4.1.2.6.182.3.6.1	INTEGER	read-only	This value specifies the number of MediaAccessDevices that are present.
INT numberOfPhysicalMedias	1.3.6.1.4.1.2.6.182.3.7.1	INTEGER	read-only	This value specifies the number of PhysicalMedia that are present.
INT numberOfPhysicalPackages	1.3.6.1.4.1.2.6.182.3.8.1	INTEGER	read-only	This value specifies the number of PhysicalPackages that are present.
INT numberOfSoftwareElements	1.3.6.1.4.1.2.6.182.3.9.1	INTEGER	read-only	This value specifies the number of SoftwareElements that are present.
NUM physicalMedia_Capacity	1.3.6.1.4.1.2.6.182.3.7.2.1.6	UINT64	read-only	The number of bytes that can be read from or written to a Media. This property is not applicable to 'Hard Copy' (documentation) or cleaner Media. Data compression should not be assumed, as it would increase the value in this property. For tapes, it should be assumed that no filemarks or blank space areas are recorded on the Media.
INT physicalMedia_CleanerMedia	1.3.6.1.4.1.2.6.182.3.7.2.1.9	INTEGER	read-only	Boolean indicating that the PhysicalMedia is used for cleaning purposes and not data storage.
INT physicalMedia_DualSided	1.3.6.1.4.1.2.6.182.3.7.2.1.10	INTEGER	read-only	Boolean indicating that the Media has two recording sides (TRUE) or only a single side (FALSE). Examples of dual sided Media include DVD-ROM and some optical disks. Examples of single sided Media are tapes and CD-ROM.
INT physicalMedia_HotSwappable	1.3.6.1.4.1.2.6.182.3.7.2.1.5	INTEGER	read-only	A PhysicalComponent is HotSwappable if it is possible to replace the Element with a physically different but equivalent one while the containing Package has power applied to it (ie, is 'on'). For example, a fan Component may be designed to be HotSwappable. All HotSwappable Components are inherently Removable and Replaceable.
STR physicalMedia_MediaDescription	1.3.6.1.4.1.2.6.182.3.7.2.1.8	DisplayString	read-only	Additional detail related to the MediaType enumeration. For example, if value 3 ('QIC Cartridge') is specified, this property could indicate whether the tape is wide or 1/4 inch, whether it is pre-formatted, whether it is Travan compatible, etc.
INT physicalMedia_MediaType	1.3.6.1.4.1.2.6.182.3.7.2.1.7	INTEGER	read-only	Specifies the type of the PhysicalMedia, as an enumerated integer. The MediaDescription property is used to provide more explicit definition of the Media type, whether it is pre-formatted, compatability features, etc.
STR physicalMedia_PhysicalLabel	1.3.6.1.4.1.2.6.182.3.7.2.1.11	DisplayString	read-only	One or more strings on 'labels' on the PhysicalMedia. The format of the labels and their state (readable, unreadable, upside-down) are indicated in the LabelFormats and LabelStates array properties.
INT physicalMedia_Removable	1.3.6.1.4.1.2.6.182.3.7.2.1.3	INTEGER	read-only	A PhysicalComponent is Removable if it is designed to be taken in and out of the physical container in which it is normally found, without impairing the function of the overall packaging. A Component can still be Removable if power must be 'off' in order to perform the removal. If power can be 'on' and the Component removed, then the Element is both Removable and HotSwappable. For example, an upgradeable Processor chip is Removable.
INT physicalMedia_Replaceable	1.3.6.1.4.1.2.6.182.3.7.2.1.4	INTEGER	read-only	A PhysicalComponent is Replaceable if it is possible to replace (FRU or upgrade) the Element with a physically different one. For example, some ComputerSystems allow the main Processor chip to be upgraded to one of a higher clock rating. In this case, the Processor is said to be Replaceable. All Removable Components are inherently Replaceable.
physicalMediaEntry	1.3.6.1.4.1.2.6.182.3.7.2.1		not-accessible	Each entry in the table contains information about a PhysicalMedia that is present in the library.
physicalMediaGroup	1.3.6.1.4.1.2.6.182.3.7
NUM physicalMediaIndex	1.3.6.1.4.1.2.6.182.3.7.2.1.1	UINT32	read-only	The current index value for the PhysicalMedia.
INT physicalMediaObjectType	1.3.6.1.4.1.2.6.182.3.7.2.1.2	INTEGER	read-only	In the 2.7 CIM Schema a Type property is no longer associated with physicalMedia. The MediaType property provides more detailed information.
physicalMediaTable	1.3.6.1.4.1.2.6.182.3.7.2		not-accessible	The PhysicalMedia class represents any type of documentation or storage medium, such as tapes, CDROMs, etc. This class is typically used to locate and manage Removable Media (versus Media sealed with the MediaAccessDevice, as a single Package, as is the case with hard disks). However, 'sealed' Media can also be modeled using this class, where the Media would then be associated with the PhysicalPackage using the PackagedComponent relationship.
STR physicalPackage_Manufacturer	1.3.6.1.4.1.2.6.182.3.8.2.1.2	DisplayString	read-only	The name of the organization responsible for producing the PhysicalElement. This may be the entity from whom the Element is purchased, but this is not necessarily true. The latter information is contained in the Vendor property of CIM_Product.
STR physicalPackage_Model	1.3.6.1.4.1.2.6.182.3.8.2.1.3	DisplayString	read-only	The name by which the PhysicalElement is generally known.
INT physicalPackage_Realizes_MediaAccessDeviceIndex	1.3.6.1.4.1.2.6.182.3.8.2.1.5	INTEGER	read-only	The index value of the the MediaAccess device that is associated with this physical package.'
STR physicalPackage_SerialNumber	1.3.6.1.4.1.2.6.182.3.8.2.1.4	DisplayString	read-only	A manufacturer-allocated number used to identify the Physical Element.
physicalPackageEntry	1.3.6.1.4.1.2.6.182.3.8.2.1		not-accessible	Each entry in the table contains information about a PhysicalPackage that is present in the library.

STR product_IdentifyingNumber	1.3.6.1.4.1.2.6.182.3.3.2	DisplayString	read-only	Product identification such as a serial number on software, a die number on a hardware chip, or (for non-commercial Products) a project number.
STR product_Name	1.3.6.1.4.1.2.6.182.3.3.1	DisplayString	read-only	Commonly used Product name.
STR product_Vendor	1.3.6.1.4.1.2.6.182.3.3.3	DisplayString	read-only	The name of the Product's supplier, or entity selling the Product (the manufacturer, reseller, OEM, etc.). Corresponds to the Vendor property in the Product object in the DMTF Solution Exchange Standard.
STR product_Version	1.3.6.1.4.1.2.6.182.3.3.4	DisplayString	read-only	Product version information. Corresponds to the Version property in the Product object in the DMTF Solution Exchange Standard.

STR softwareElement_IdentificationCode	1.3.6.1.4.1.2.6.182.3.9.2.1.9	DisplayString	read-only	The value of this property is the manufacturer's identifier for this software element. Often this will be a stock keeping unit (SKU) or a part number.
STR softwareElement_LanguageEdition	1.3.6.1.4.1.2.6.182.3.9.2.1.10	DisplayString	read-only	The value of this property identifies the language edition of this software element. The language codes defined in ISO 639 should be used. Where the software element represents multi-lingual or international version of a product, the string multilingual should be used.
STR softwareElement_Manufacturer	1.3.6.1.4.1.2.6.182.3.9.2.1.5	DisplayString	read-only	Manufacturer of this software element
STR softwareElement_Name	1.3.6.1.4.1.2.6.182.3.9.2.1.2	DisplayString	read-only	The name used to identify this software element

NUM softwareElementIndex	1.3.6.1.4.1.2.6.182.3.9.2.1.1	UINT32	read-only	The current index value for the SoftwareElement.
softwareElementTable	1.3.6.1.4.1.2.6.182.3.9.2		not-accessible	The CIM_SoftwareElement class is used to decompose a CIM_SoftwareFeature object into a set of individually manageable or deployable parts for a particular platform. A software element's platform is uniquely identified by its underlying hardware architecture and operating system (for example Sun Solaris on Sun Sparc or Windows NT on Intel). As such, to understand the details of how the functionality of a particular software feature is provided on a particular platform, the CIM_SoftwareElement objects referenced by CIM_SoftwareFeatureSoftwareElement associations are organized in disjoint sets based on the TargetOperatingSystem property. A CIM_SoftwareElement object captures the management details of a part or component in one of four states characterized by the SoftwareElementState property.
STR storageLibrary_Caption	1.3.6.1.4.1.2.6.182.3.5.3	DisplayString	read-only	The Caption property is a short textual description (one- line string) of the object.

STR storageLibrary_Status	1.3.6.1.4.1.2.6.182.3.5.4	DisplayString	read-only	A string indicating the current status of the object. Various operational and non-operational statuses are defined. This property is deprecated in lieu of OperationalStatus, which includes the same semantics in its enumeration. This change is made for three reasons: 1) Status is more correctly defined as an array property. This overcomes the limitation of describing status via a single value, when it is really a multi-valued property (for example, an element may be OK AND Stopped. 2) A MaxLen of 10 is too restrictive and leads to unclear enumerated values. And, 3) The change to a uint16 data type was discussed when CIM V2.0 was defined. However, existing V1.0 implementations used the string property and did not want to modify their code. Therefore, Status was grandfathered into the Schema. Use of the Deprecated qualifier allows the maintenance of the existing property, but also permits an improved definition using OperationalStatus.
