NAME
sg_safte - Fetch status from a SCSI Accessed Fault-Tolerant Enclosure (SAF-TE) deviceSYNOPSIS
sg_safte [--config] [--devstatus] [--encstatus] [--flags] [--help] [--hex] [--insertions] [--raw] [--usage] [--verbose] [--version] DEVICEDESCRIPTION
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
The implementation is based on the intermediate review document eg as found athttp://www.intel.com/design/servers/ipmi/saf-te.htm
As the specification was never finalized this document serves as the de-facto standard.
Similar functionality is provided by SPC-4 SCSI Enclosure Services 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.AUTHORS
