Viewing attributes for SMI-S storage devices

Attributes for SMI-S storage devices can include four sets of data values: Default, CIMOM, Base and Extended. This topic describes how to view these attributes and provides definitions for each.

To display the attributes for an SMI-S storage device, in the Group Contents pane, double-click on a storage managed object.
An SMI-S storage managed object appears on the console immediately after being discovered through SLPv2 as a locked object labeled by the host name (or IP address if DNS lookup fails). Default attributes common to IBM Director managed objects appear at this time. These include:
System Name
Starts as the primary host name or IP address of the CIMOM. Once unlocked, the generated name for the device.
System Factory ID
The managed object factory that creates the objects—"SMI-S Storage Devices."
System State
State of the object. Starts as Unknown because access is required to determine the actual online, error or offline status.
System Presence Check Setting
Polling interval in minutes for checking the status.
Secure/Unsecure supported
Specifies whether securing of the target is supported.
Access Denied
True for a locked object. This attribute goes away once the object is unlocked.
Encryption Enabled
Specifies whether encryption to the target is enabled.

At this point, only the public data surfaced through SLPv2 is available (such as a locked object that represents the CIMOM required by the SMI-S standard). Until access is obtained to the represented CIMOM and the CIM schemas mined for data, the actual device(s) and the associated data is unavailable.

The list of SLP provided CIMOM attributes includes:
SMI-S Provider Service ID
The unique service id of the CIMOM. As specified in SMI-S, responses from different IP addresses with the same Service ID value are assumed to be the same CIMOM and collapsed together.
Interop Namespace
The entry namespace in CIM containing the Server profile that has the CIMOM data and list of registered profiles.
Registered Profiles Supported
The list of profiles this CIMOM claims to support.
SLP Service Names
The full service name(s) for this CIMOM
TCP/IP Addresses
The list of one or more IP addresses for the CIMOM.
SMI-S Provider IP Port Numbers
The IP ports on this CIMOM.
Once access is granted, the full CIM data can be obtained. This may result in the device representation going away successfully because the entity already exists, or the object access failing or security problem. If access is successful, the object becomes a representation of an actual device. The name changes based on the rules specified in the Discovery Preferences panel for SMI-S Storage Devices. The following base attributes then appear:
Registered Profile
The profile this device represents along with the version. Ex: "SNIA:Array 1.0.2".
Namespace
The namespace with the schema details about this particular profile.
Manufacturer
The manufacturer of this device.
Type and Model
Type and model string representing this device
Serial Number
Serial number for the device
Endpoint Unique Name
Unique identifier (primary FC port in fibre channel).
Storage Device Type
Specifies whether this is a fibre channel or iSCSI device.
Finally, any extended attributes specified by the attribute extension files are created. These may vary based on the device. For example, for an IBM DS4000 disk array the following values are gathered:
Subscriptions
Indicates whether a managed object is registered to receive state or alert indications.
Nickname
A name for the device
Controller IP Addresses
IP addresses for the controllers on the target.
