Abstract
A shared storage system includes a plurality of storage processors. A first storage processor of the plurality of storage processors is coupled with a shared storage device having a plurality of storage devices. The first storage processor receives a first verify connectivity request from an initiator device. In response to the first verify connectivity request, the first storage processor transmits a first ready response to the initiator device. After transmitting the first ready response, the first storage processor detects that the first storage processor is decoupled from the shared storage device. In accordance with detecting that the first storage processor is decoupled from the shared storage device, the first storage processor transmits a not-ready response to the initiator device in response to a second verify connectivity request from the initiator device.
