This read-only object mirrors the `rn` property of a capability-catalog provider record that stores the hardware-capability data Cisco ships for a specific local-disk (drive) model inside Cisco UCS Manager's internal information model, exposed here as a text string for this drive capability-catalog entry. The rn is just this object's own naming segment -- the last component appended to its parent's dn to build the full path -- rather than the whole path itself. For the catalog record covering a supported SAS SSD model, the rn might be a short token like ioexpander-1 or locator-led-1, which UCS Manager concatenates onto the parent blade's dn.
