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.
