NAME

       sg_safte - access SCSI Accessed Fault-Tolerant Enclosure (SAF-TE) device

SYNOPSIS

       sg_safte  [--config] [--devstatus] [--encstatus] [--flags] [--help] [--hex] [--insertions]
       [--raw] [--usage] [--verbose] [--version] DEVICE

DESCRIPTION

       Fetches enclosure status (via a SCSI READ BUFFER command).  The DEVICE should be a  SAF-TE
       device  which  may be a storage array controller (INQUIRY peripheral device type 0xc) or a
       generic processor device (INQUIRY peripheral device type 0x3).

       If no options are given (only the DEVICE argument) then the overall  enclosure  status  as
       reported by the option --config ®is reported.

OPTIONS

Arguments to long options are mandatory for short options as well. The options are
arranged in alphabetical order based on the long option name.

-c, --config
will issues a Read Enclosure Configuration ®(READ BUFFER ID 0) cdb to the device,
which returns a list of the enclosure hardware resources.

-d, --devstatus
will issue a Read Device Slot Status ®(READ BUFFER ID 4) cdb to the device, which
returns information about the current state of each drive or slot.

-s, --encstatus
will issue a Read Enclosure Status ®(READ BUFFER ID 1) cdb to the device, which
returns the operational state of the components.

-f, --flags
will issue a Read Global Flags ®(READ BUFFER ID 5) cdb to the device, which read
the most recent state of the global flags of the RAID processor device.

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

-H, --hex
output the response to a READ BUFFER command in ASCII hex to stdout. If used once,
output the response to the first READ BUFFER command (i.e. with buffer_id=0). This
should be the enclosure configuration. If used twice (or more often), the response
to subsequent READ BUFFER commands is output.

-i, --insertions
will issue a Read Device Insertions ®(READ BUFFER ID 3) cdb to the device, which
returns information about the number of times devices have been inserted whilst the
RAID system was powered on.

-r, --raw
output the response to a READ BUFFER command in binary to stdout. If used once,
output the response to the first READ BUFFER command (i.e. with buffer_id=0). This
should be the enclosure configuration. If used twice (or more often), the response
to subsequent READ BUFFER commands is output.

-u, --usage
will issue a Read Usage Statistics ®(READ BUFFER ID 2) cdb to the device, which
returns the information on total usage time and number of power-on cycles of the
RAID device.

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

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

NOTES

       This implementation is based on the intermediate review document dated 19970414 and  named
       "SR041497.pdf".  So  it  is  quite  old. Intel and nStor are the authors. Intel have a zip
       archive containing this and related documents in the "SAF-TE: SCSI Accessed Fault Tolerant
       Enclosures Interface Specification" section of this page:

       http://www.intel.com/content/www/us/en/servers/ipmi/ipmi-technical-resources.html

       Similar  functionality  is  provided  by  SPC-4  SCSI  Enclosure  Services  (SES)  devices
       (Peripheral device type 0xd), which can be queried with the sg_ses utility.

EXAMPLES

       To view the configuration:

          sg_safte /dev/sg1

       To view the device slot status:

          sg_safte --devstatus /dev/sg1

EXIT STATUS

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