Abstract
A method of enforcing active-active cluster input/output fencing through out-of-band management network for hung cluster nodes is disclosed. In accordance with one embodiment of the present disclosure, a method of resetting a cluster node in a shared storage system includes identifying the cluster node from a plurality of cluster nodes based on the cluster node failing to respond to a cluster service application. The method further includes propagating a reset signal to the cluster node using an out-of-band channel to perform a hardware reset of the cluster node.

A method of resetting a cluster node in a shared storage system, the method comprising:
- identifying the cluster node from a plurality of cluster nodes based on the cluster node failing to respond to a cluster service application;
- and
- propagating a reset signal to the cluster node using an out-of-band channel to perform a hardware reset of the cluster node.
A system for resetting a hung cluster node using a hardware reset, comprising:
- a plurality of cluster nodes forming a part of a network;
- a cluster service application operable to monitor the health of each of the plurality of cluster nodes;
- a quorum stored in the system, the quorum indicating an available status for each of the plurality of cluster nodes;
- wherein the cluster service application is operable to change the available status for a particular cluster node listed in the quorum if the particular cluster node fails to respond to the cluster service application;
- and
- a cluster agent operable to transmit the hardware reset to the particular cluster node using an out-of-band channel based on a change of available status of the particular cluster node in the quorum.
A computer-readable medium having computer-executable instructions for resetting a cluster node in an information handling system, comprising:
- instructions for identifying the cluster node from a plurality of cluster nodes based on the cluster node failing to respond to a cluster service application;
- and
- instructions for propagating a reset signal to the cluster node using an out-of-band channel to perform a hardware reset of the cluster node.
