in response to generating the management command, accessing the cache storage to identify the cached unique identifier and the cached firmware version for the particular device;
transmitting, by the management software module and to a device driver associated with the particular device or to the particular device, the management command and data indicating the cached unique identifier and the cached firmware version for the particular device;
determining, by the device driver or the particular device, that i) the cached unique identifier matches a current unique identifier for the particular device and ii) the cached firmware version matches a current firmware version for the particular device; and
in response to the matching, completing the management command at the particular device.
11. The system of claim 10 , the operations further comprising:
determining, by the device driver or the particular device, that the cached unique identifier does not match the current unique identifier for the particular device; and
in response to determining that the cached unique identifier does not match the current unique identifier for the particular device, rejecting the management command at the particular device.
12. The system of claim 10 , the operations further comprising:
determining, by the device driver or the particular device, that the cached firmware version does not match the current firmware version for the particular device; and
in response to determining that the cached firmware version does not match the current firmware version for the particular device, rejecting the management command at the particular device.
13. The system of claim 10 , wherein the unique identifier for each device is based on one or more properties of the device, the properties including, for each device, one or more of a serial number of the device, a state of the device, and a current configuration of the device.
