Enclosure Services Information (ESI)
The drives supported by the manual do not process the contents of the SCSI Enclosure Service (SES) pages. The
drive attempts to transfer the page contents to or from the enclosure using the Enclosure Services Interface (ESI) as
directed by the command. Errors detected in the transfer are returned to the initiator in response to the command.
See ANSI document X3T10 NCITS 305-199x regarding the SCSI-3 Enclosure Services Command Set (SES) for
descriptions of the data presented in the SES pages.

The data returned by the subsequent Receive Diagnostic Results command use the diagnostic page format
described in the ANSI SCSI-2 specification. PF needs to be on, set to 1, for ESI pages 01h through 0Fh and
requires no subsequent Receive Diagnostic command. Further, ESI requests for page 01h through 0Fh are sent
without any prior Send Diagnostic request. See Tables 208 and 209 which show formats of the two pages supported
by disc drive.
Self-Test
0
Requests that the device server perform the Device Self-Test operation specified by the Self-Test Code field or in
the parameter list. The diagnostic operation might or might not require the device server to return parameter data
that contains diagnostic results. If the return of parameter data is not required, the return of Good status indicates
successful completion of the diagnostic operation. If the return of parameter data is required, the device server
either:
- performs the requested diagnostic operation, prepare the parameter data to be returned and indicate completion
by returning Good status. The application client issues a Receive Diagnostic Results command to recover the
parameter data; or
