  where:
    -a     fetch and decode all log pages
    -A     fetch and decode all log pages and subpages
    -b     shorten the output of some log pages
    -c=PC  page control(PC) (default: 1)
                  0: current threshhold, 1: current cumulative
                  2: default threshhold, 3: default cumulative
    -h     output in hex (default: decode if known)
    -H     output in hex (same as '-h')
    -l     list supported log page names (equivalent to '-p=0')
    -L     list supported log page and subpages names (equivalent to
           '-p=0,ff')
    -m=LEN   max response length (decimal) (def: 0 -> everything)
    -n       decode some pages into multiple name=value lines
    -p=PG    page code in hex (def: 0)
    -p=PG,SPG    both in hex, (defs: 0,0)
    -paramp=PP   (in hex) (def: 0)
    -pcb   show parameter control bytes in decoded output


tool: D15:     -ppc   set the Parameter Pointer Control (PPC) bit (def: 0)
    -r     reset log parameters (takes PC and SP into account)
           (uses PCR bit in LOG SELECT)
    -select  perform LOG SELECT using SP and PC values
    -sp    set the Saving Parameters (SP) bit (def: 0)
    -t     outputs temperature log page (0xd)
    -T     outputs transport (protocol specific port) log page (0x18)
    -v     increase verbosity
    -V     output version string
    -?     output this usage message

Performs a SCSI LOG SENSE (or LOG SELECT) command
