SES_DOWNLOAD_MICROCODE_STATUS_DESCRIPTOR structure (scsi.h)

  • Article

The SES_DOWNLOAD_MICROCODE_STATUS_DESCRIPTOR structure specifies the status and additional status of a download microcode.

Syntax

typedef struct _SES_DOWNLOAD_MICROCODE_STATUS_DESCRIPTOR {
  UCHAR Reserved1;
  UCHAR SubEnclosureId;
  UCHAR Status;
  UCHAR AdditionalStatus;
  UCHAR MaximumImageSize[4];
  UCHAR Reserved2[3];
  UCHAR ExpectedBufferId;
  UCHAR ExpectedBufferOffset;
} SES_DOWNLOAD_MICROCODE_STATUS_DESCRIPTOR, *PSES_DOWNLOAD_MICROCODE_STATUS_DESCRIPTOR;

Members

Reserved1

Reserved for future use.

SubEnclosureId

Specifies the subenclosure to which the download microcode status descriptor applies to.

Status

Specifies the status of download microcode operations for the subenclosure. After reporting a code indicating completion, the enclosure services process shall set this field to 0x00 and shall set the AdditionalStatus field to 0x00. Status may can contain one of the following values:

Value Meaning
0x00
 No download microcode operation is in progress.
0x01
 Download microcode operation is in progress. The enclosure services process has received one or more Download Microcode Control diagnostic pages and is awaiting additional microcode data.
0x02
 Download microcode operation data transfer is complete, currently updating nonvolatile storage.
0x03
 The enclosure services process is currently updating nonvolatile storage with deferred microcode.
0x04 to 0x0F
 Reserved for codes indicating interim status
0x10
 Download microcode operation complete with no error. The enclosure services process begins using the new microcode after returning this status.
0x11
 Download microcode operation complete with no error. The enclosure services process (e.g., a standalone enclosure services process) begins using the new microcode after the next hard reset or power on.
0x12
 Download microcode operation complete with no error. The enclosure services process (e.g., an attached enclosure services process) begins using the new microcode after the next power on.
0x13
 Download microcode operation complete with no error. The enclosure services process (e.g., an attached enclosure services process) begins using the new microcode after either processing a SES_DOWNLOAD_MICROCODE_CONTROL_DIAGNOSTIC_PAGE specifying the activate deferred microcode mode, hard reset, or power on.
0x14 to 0x6F
 Reserved for codes indicating no error.
0x70 to 0x7F
 Vendor specific
0x80
 Error in one or more of the Download Microcode Control diagnostic page fields.
0x81
 Specifies a Microcode image error.
0x82
 Download microcode timeout. The enclosure services process may discard microcode data after a vendor specific amount of time, if it does not receive the entire microcode image.
0x83
 Internal error in the download microcode operation. New microcode image is needed before a hard reset or power on
0x84
 Internal error in the download microcode operation. Hard reset and power on safe
0x00
 Processed a SES_DOWNLOAD_MICROCODE_CONTROL_DIAGNOSTIC_PAGE with the Mode field set to 0x0F (i.e., activate deferred microcode), if there is no deferred microcode.
0x86 to 0x0EF
 Reserved for codes indicating errors.
0xF0 to 0xFF
 Vendor Specific

AdditionalStatus

Provides an additional status value for certain values of Status .

MaximumImageSize[4]

Indicates the maximum size in bytes of the microcode image that the enclosure services process accepts. The image may be delivered using one or more SES_DOWNLOAD_MICROCODE_CONTROL_DIAGNOSTIC_PAGE.

Reserved2[3]

Reserved for future use.

ExpectedBufferId

Indicates the next value that the enclosure services process expects in the BufferId field in SES_DOWNLOAD_MICROCODE_CONTROL_DIAGNOSTIC_PAGE.

ExpectedBufferOffset

Indicates the next value that the enclosure services process expects in the BufferOffset field in SES_DOWNLOAD_MICROCODE_CONTROL_DIAGNOSTIC_PAGE. If the enclosure services process accepts arbitrary BufferOffset values, then it shall set ExpectedBufferOffset to 0xFFFFFFFF.
