NAME
sg_safte - access SCSI Accessed Fault-Tolerant Enclosure (SAF-TE) de-
vice
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 (IN-
QUIRY peripheral device type 0xc) or a generic processor device (IN-
QUIRY peripheral device type 0x3).
If no options are given (only the DEVICE argument) then the overall en-
closure 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 hard-
ware 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 compo-
nents.
-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 en-
closure configuration. If used twice (or more often), the re-
sponse 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 std-
out. 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 In-
terface Specification" section of this page:
http://www.intel.com/content/www/us/en/servers/ipmi/ipmi-technical-re-
sources.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.
