SG_COPY_RESULTS(8)

NAME
sg_copy_results - send SCSI RECEIVE COPY RESULTS command (XCOPY related)

SYNOPSIS
sg_copy_results [--failed|--params|--receive|--status] [--help] [--hex] [--list_id=ID] [--verbose] [--version] [--xfer_len=BTL] DEVICE

DESCRIPTION

This utility is designed to query the status of the SCSI Extended Copy facility (see SPC-3 revision 23 sections 6.3 and 6.17), present in some modern storage arrays. This utility sends a SCSI RECEIVE COPY RESULTS command to the given DEVICE and displays the response.

The command has four distinct modes of operation, distinguished by the service action field:

COPY STATUS
    Displays the current status of the EXTENDED COPY command identified by the list id field.

RECEIVE DATA
    Return the held data read by the EXTENDED COPY command identified by the list id field. This option is only meaningful if the respective segment descriptor are supported.

OPERATING PARAMETERS
    Return copy manager operating parameters. This option is also useful to determine if the SCSI Extended Copy facility is supported.

FAILED SEGMENT DETAILS
    Return copy target device sense data and other information about any failed segments.

OPTIONS
Arguments to long options are mandatory for short options as well.

-f, --failed
    sets the service action field to FAILED SEGMENT DETAILS [4].

-h, --help
    output the usage message then exit.

-H, --hex
    prints out the response buffer in hex.

-l, --list_id=ID
    sets the list identifier field to ID (default: 0).

-p, --params
    sets the service action field to OPERATING PARAMETERS [3]. This is the default.

-r, --receive
    sets the service action field to RECEIVE DATA [1].

-s, --status
    sets the service action field to COPY STATUS [0].

-v, --verbose
    increase the level of verbosity, (i.e. debug output).

-V, --version
    print the version string and then exit.

-x, --xfer_len=BTL
    sets the allocation length field to BTL. It is the byte transfer length and is the maximum (byte) size of the response. BTL must be less than 10000 and defaults to 520.

NOTES
Decoding of RECEIVE DATA service action is not implemented.

EXAMPLES
Query the operating parameters for a device:

# sg_copy_results -p /dev/sdo
Receive copy results (report operating parameters):
    Supports no list identifier: no
    Maximum target descriptor count: 2
    Maximum segment descriptor count: 1
    Maximum descriptor list length: 92 bytes
    Maximum segment length: 33553920 bytes
    Inline data not supported
    Held data limit: 0 bytes
    Maximum stream device transfer size: 0 bytes
    Total concurrent copies: 0
    Maximum concurrent copies: 255
    Data segment granularity: 512 bytes
    Inline data granularity: 1 bytes
    Held data granularity: 1 bytes
    Implemented descriptor list:
        Segment descriptor 0x02: Copy from block device to block device
        Target descriptor 0xe4: Identification descriptor

EXIT STATUS
The exit status of sg_copy_results is 0 when it is successful. Otherwise see the sg3_utils(8) man page.
