HBA_SendRPS
HBA_SendRLS (current via response buffer of HBA_SendRPS)

3. Additional Notes

• FC Port ID format: Currently, the FC Port ID is always returned by the QLogic defined SDM API in 3 byte fields. However, the SNIA defined Common API returns the FC Port ID in a 32-bit field. In libqlsdm version 1.10 Beta+ and Linux HBA driver version 4.35 Beta and later, the ioctl and API implementations treat this 32-bit field as if it were an array of 4 bytes, and store the FC Port ID in bytes 1, 2, and 3 of this array. Byte 0 of this 32-bit field is treated as a reserved field.
• HBA_SendRNID data format: The data format for this function has been changed. The resulting data is shifted down 4 bytes compared to the format defined in the SNIA specification. The value of the newly created 4 bytes at the beginning of the returned data should be ignored as they are currently only hard-coded values. The function return status still represents the actual response status of the RNID command sent.
• Other features not supported: Currently Linux API library does not support any externally available NVRAM and diagnostics related API function. These supports are planned for a later date.
