Abstract
A method, system and computer program product for facilitating communication among storage controllers of a storage system. The method comprises detecting an event indicative of status change in a storage system having a plurality of storage controllers; determining that it is needed to communicate the event from a first storage controller to a second storage controller of the storage controllers; transmitting a message about the event from the first storage controller to a host in response to failure of a dedicated link between the first storage controller and the second storage controller; and forwarding the message from the host to the second storage controller.
Claims18
A computer-implemented method, comprising:
- transmitting, by one or more processors, a message about an event indicative of a status change in a storage system from a first storage controller to a host in response to failure of a dedicated link between the first storage controller and a second storage controller, wherein the first storage controller is attached to the host;
- and
- forwarding, by one or more processors, the message from the host to the second storage controller.
A system comprising:
- one or more processors;
- and
- a computer-readable memory coupled to the one or more processors, the computer-readable memory comprising instructions that when executed by the one or more processors perform actions of:
- detecting an event indicative of status change in a storage system having a plurality of storage controllers;
- determining that it is needed to communicate the event from a first storage controller to a second storage controller of the plurality of storage controllers;
- transmitting a message about the event from the first storage controller to a host in response to failure of a dedicated link between the first storage controller and the second storage controller, where in the first storage controller is attached to the host;
- and
- forwarding the message from the host to the second storage controller.
A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to perform actions of:
- transmitting a message about an event indicative of a status change in a storage system having plurality of storage controllers from a first storage controller to a host in response to failure of a dedicated link between the first storage controller and a second storage controller, where in the first storage controller is attached to the host;
- and
- forwarding the message from the host to the second storage controller.
