Claim:
A method for performing a takeover of storage devices of a failing node in a clustered storage system, comprising: at a failing node, detecting a failure status, and initiating a coredump process and sending a message to a takeover node notifying the takeover node of the coredump process; at a failing node, selecting a storage device for the coredump and obtaining unique storage device identification information of coredump storage device; at a failing node, generating a message that includes said unique storage device identification information and sending the message across a cluster interconnect to the takeover node in the cluster; at the takeover node, upon receipt of said message from the failing node, said takeover node starting a takeover process simultaneously with said failing node performing said coredump process including resetting one or more storage adapters at said failing node simultaneously with said takeover node asserting reservations on the storage devices excluding the coredump storage device, and at the failing node, performing a coredump write process, and at said takeover node, further obtaining said unique storage device identification information and asserting reservations on the coredump storage device.
