With r319610, sesutil started twiddling the bits of every SES device. Not everything is a disk slot, there are also fan controllers, temperature sensors, even power supplies, among other things controlled by SES. Add a type check to make sure we are only operating on device slot and array device slot elements. Other type elements will be skipped, but it would be simple to add additional cases for controlling the ident LEDs of other element types (which are not necessarily the same bits). Rather than doing raw bit manipulation of an unstructured byte array using unnamed numeric constants, leverage existing code abstractions.

FreeBSD
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
