Sends a SCSI SET RNID command to a remote port of the end device.
Common Host Bus Adapter Library (libHBAAPI.a)
#include <hbaapi.h> HBA_STATUS HBA_SetRNIDMgmtInfo (handle, pInfo) HBA_HANDLE handle; HBA_MGMTINFO *pInfo;
The HBA_SetRNIDMgmtInfo subroutine sends a SCSI SET RNID (Request Node Identification Data) command with the SCIOLCHBA operation as its argument. This is done through a call to ioctl. The arg parameter for the SCIOLCHBA operation is the address of a scsi_chba structure. This structure is defined in the /usr/include/sys/scsi_buf.h file. The scsi_chba parameter block allows the caller to select the SET RNID command to be sent to the adapter. The pInfo structure stores the RNID data to be set. The pInfo structure is defined in the /usr/include/sys/hbaapi.h file. The structure includes:
If successful, the SET RNID data in pInfo is sent to the adapter.
| handle | Specifies the open file descriptor obtained from a successful call to the open subroutine. |
| pInfo | Specifies the structure containing the information to be set or received from the RNID command |
Upon successful completion, the HBA_SetRNIDMgmtInfo subroutine returns a value of HBA_STATUS_OK, or a value of 0. If unsuccessful, a value of HBA_STATUS_ERROR, or a 1 is returned.
The Storage Area Network Host Bus Adapter API subroutines return the following error codes:
| HBA_STATUS_OK | A value of 0 on successful completion. |
| HBA_STATUS_ERROR | A value of 1 if an error occurred. |
| HBA_STATUS_ERROR_INVALID_HANDLE | A value of 3 if there was an invalid file handle. |
