Abstract
Described are techniques for indicating a state associated with a device. A request is received over a path for information about a device. A response to the request is sent. The response indicates a state regarding the device on the path. The response has a response status of good and a payload of a varying size. The payload is truncated at a location prior to that at which a device identifier for the device is expected. In accordance with the response, a state regarding the device on the path is determined.
Claims20
A method for indicating a state associated with a device comprising:
- sending a request over a path for information about a device;
- receiving a response to said request;
- and
- determining, in accordance with said response having a payload truncated at a location prior to that at which a device identifier for the device is expected and having a response status of good, a state regarding a combination of said device and said path.
A system comprising:
- a data storage system comprising a non-transitory computer readable medium with code stored thereon for:
- receiving a request over a path for information about a device;
- and
- sending a response to said request;
- and
- a host comprising a non-transitory computer readable medium with code stored thereon for:
- sending said request;
- receiving said response;
- and
- determining, in accordance with said response having a payload truncated at a location prior to that at which a device identifier for the device is expected and having a response status of good, a state regarding a combination of said device and said path.
A non-transitory computer readable medium comprising code stored thereon for indicating a state associated with a device, the non-transitory computer readable medium comprising code stored thereon for:
- sending a request over a path for information about a device;
- receiving a response to said request;
- and
- determining, in accordance with said response having a payload truncated at a location prior to that at which a device identifier for the device is expected and having a response status of good, a state regarding a combination of said device and said path.
