The DMI specification has reserved ComponentId=1 for the DMI SP. The specification also defines the MIF file for the SP. The network administrator must take this into consideration when creating the .MAP files or when specifying the OID preference as a command-line parameter to the miftomib utility. Every MIF file must contain a standard group with ID 1.
Table 6-4 ComponentID Group Translated to DMI MIB
MIS Object Identifier and SYNTAX |
MIF Data |
Description |
Notes |
---|---|---|---|
DMIcompindex INTEGER (1...217483647) |
Component ID |
Unique value for component |
Assigned at installation by the SP, it communicates with this component until uninstalled; managing applications record this ID to request attributes later |
DMIcompManufacture DisplayString (0...64) |
Attribute "Manufacture" |
Value assigned by the component provider |
The name of the organization that produced this component |
DMIcompProduct DisplayString (0...64) |
Attribute "Product" |
Value assigned by the component provider |
Name of the component |
DMIcompVersion DisplayString (0...64) |
Attribute "Version" |
Value assigned by the component provider |
Version of the component |
DMIcompSerialnumber DisplayString (0...64) |
Attribute "Serial Number" |
Value assigned by the component provider |
Serial number of component |
DMIcompInstallation Date |
Attribute "Installation" |
Value assigned by the SP at installation time |
28-octet displayable string composed of date and time |
DMIcompVerify Integer (0...7) |
Attribute "Verify" |
Verification level of this component at installation time |
A request for this attribute causes the component to find out if it is still in the system and working properly |
With this mapping, any MIF that is installed with the DMI has at minimum the ComponentID Group visible to management applications. All attributes within this group have read-only access. As MIFs become standard and are translated into MIBs, they become accessible but have additional anchor points in the DmtfGroups tree. For example, if the software MIF were defined, the translation would provide a DMISW MIB and be anchored as follows:
enterprise.sun.DmtfGroups.DMISW(2)
or
1.3.6.1.4.1.42.2000.3
Managing applications must be prepared for the same component to be visible in two different branches of the DmtfGroups tree.
