Usage for general access:
    sg_ses  [--all] [--ALL] [--descriptor=DES] [--dev-slot-num=SN]
            [--eiioe=A_F] [--filter] [--get=STR] [--hex]
            [--index=IIA | =TIA,II] [--inner-hex] [--join] [--json[=JO]]
            [--js-file=JFN] [--maxlen=LEN] [--no-config] [--no-time]
            [--page=PG] [--quiet] [--raw] [--readonly] [--sas-addr=SA]
            [--status] [--verbose] [--warn] DEVICE

  where the main general access options are:
    --all|-a            same as --join followed by remaining SES dpages
    --descriptor=DES|-D DES    descriptor name (for indexing)
    --dev-slot-num=SN|--dsn=SN|-x SN    device slot number (for indexing)
    --filter|-f         filter out enclosure status flags that are clear
                        use twice for status=okay entries only
    --get=STR|-G STR    get value of field by acronym or position
    --help|-h           print out usage message, use multiple times for more
    --index=IIA|-I IIA    individual index ('-1' for overall) or element
                          type abbreviation (e.g. 'arr'). A range may be
                          given for the individual index (e.g. '2:5')
    --index=TIA,II|-I TIA,II    comma separated pair: TIA is type header
                                index or element type abbreviation;
                                II is individual index ('-1' for overall)
    --join|-j           group Enclosure Status, Element Descriptor
                        and Additional Element Status pages. Use twice
                        to add Threshold In page
    --json[=JO]|-J[=JO]    output in JSON instead of plain text.
                           Use --json=? for JSON help
    --page=PG|-p PG     diagnostic page code (abbreviation or number)
                        (def: 'ssp' [0x0] (supported diagnostic pages))
    --sas-addr=SA|-A SA    SAS address in hex (for indexing)
    --status|-s         fetch status information (default action)

The 'general access' usage fetches pages or fields from a SCSI enclosure.
Use '-hh' (or more) for further usage patterns, '-hh' displays the
'control' usage. For examples see '-hhhh' . The term 'diagnostic page'
is often abbreviated to 'dpage'.
