1. A data storage device comprising:
a plurality of memory dies; and
a processor configured to communicate with the plurality of memory dies and further configured to:
in response to determining that a subset of the plurality of memory dies is non-responsive, inform a host that the data storage device will perform a hardware reset on the subset of the plurality of memory dies;
in response to receiving an acknowledgment from the host, perform the hardware reset on the subset of the plurality of memory dies by:
sending a command to all memory dies of the plurality of memory dies to ignore a hardware reset command, wherein because the subset of the plurality of memory dies is non-responsive, the subset of the plurality of memory dies does not receive the command to ignore the hardware reset command; and
sending the hardware reset command on a communication channel shared by the plurality of memory dies; and
inform the host after the hardware reset on the subset of the plurality of memory dies has been performed.
