SES-2 Commands
The SES-2 command set uses the SCSI SEND DIAGNOSTIC and RECEIVE DIAGNOSTIC RESULTS commands to obtain configuration information for the enclosure and to set and sense standard bits for each element installed in the enclosure. The SEND DIAGNOSTIC command is used to send control information to internal or external LED indicators or to instruct one enclosure element to change its state or perform an operation. Access to the e The application client has two mechanisms for accessing the enclosure service process:
- a) Directly to a standalone enclosure services process, for example an enclosure controller chip. SCSI conditions communicated directly include hard reset, logical unit Reset and I_T nexus loss.
- b) Indirectly through a LUN of another peripheral device – for example a drive within the enclosure. The drive will communicate with the Enclosure Through the Enclosure Services Interface. In this case the only SCSI device condition communicated through the LUN is hard reset.
