Variable Name

Variable Description

The command block. The values of iCommand are:

DmiListAttributeCmd

0x208
DmiListFirstAttributeCmd
0x209
DmiListNextAttributeCmd
0x20a
iComponentId
The ID of the desired component.
iGroupId
The ID of the desired group within the component identified by iComponentId.
iAttributeId
The ID of the desired attribute within the group. In DmiListFirstAttributeCmd, this field is ignored. For the DmiListNextAttributeCmd command, the service layer starts filling the confirm buffer beginning with the attribute ID that follows the value in this field. To start at the first attribute, set this field to zero. On return from the command, the service layer updates this field with the ID of the last attribute put in the confirm buffer. The management application can continue issuing DmiListNextAttributeCmd commands until the returned iStatus field indicates that there is no more data.

Issuing DmiListAttributeReq displays an example of how to issue the DmiListAttributeReq command to the MI. IssuingDmiListAttributeReq
