SG_SAFTE(8) SG3_UTILS SG_SAFTE(8) NAME sg_safte - Fetch status from a 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 (R)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 (R)(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 (R)(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 (R)(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 (R)(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 BUF- FER command (i.e. with buffer_id=0). This should be the enclo- sure configuration. If used twice (or more often), the response to subsequent READ BUFFER commands is output. -i, --insertions will issue a Read Device Insertions (R)(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 (R)(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. ATTRIBUTES See attributes(5) for descriptions of the following attributes: +---------------+--------------------------+ |ATTRIBUTE TYPE | ATTRIBUTE VALUE | +---------------+--------------------------+ |Availability | system/storage/sg3_utils | +---------------+--------------------------+ |Stability | Uncommitted | +---------------+--------------------------+ NOTES The implementation is based on the intermediate review document eg as found at http://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 Written by Hannes Reinecke and Douglas Gilbert. REPORTING BUGS Report bugs to <dgilbert at interlog dot com>.
