I think this should rather be something like
.IR /sys/class/scsi_disk/ c : b : t : l /device/lunid
These rules from groff_man_style(7) apply:
Use italics for file and path names, ...
... An exception involves vari‐
ant text in a context already typeset in italics, such
as file or path names with replaceable components; in
such cases, follow the convention of mathematical typog‐
raphy: set the file or path name in italics as usual but
use roman for the variant part (see .IR and .RI below),
...
Thanks,
Alex
