Abstract
Systems, methods, and computer readable storage mediums for generating an alert on a failure of a storage subsystem to phone home to the cloud in a replication environment. A dataset is replicated from a first storage subsystem to a second storage subsystem. The first and second storage subsystems also phone home log data to the cloud on a periodic basis. In response to detecting a failure of the first storage subsystem to phone home, the cloud generates and sends an alert to the second storage subsystem. In response to receiving this alert, the second storage subsystem starts disaster recovery operations for the dataset.
Claims17
A system comprising:
- a first storage subsystem;
- a second storage subsystem;
- and
- a cloud-based service;
- wherein the first storage subsystem is configured to replicate a dataset to the second storage subsystem;
- and
- wherein responsive to detecting one or more conditions indicative of an impending failure of the first storage subsystem, the cloud-based service is configured to:
- generate and convey an alert to the second storage subsystem;
- select a third storage subsystem to take over as a replication target of the dataset;
- and
- identify a highest medium identifier (ID) of the dataset already stored on the third storage subsystem.
A method comprising:
- replicating a dataset from a first storage subsystem to a second storage subsystem;
- and
- responsive to detecting one or more conditions indicative of an impending failure of the first storage subsystem:
- generating and conveying an alert from a cloud-based service to the second storage subsystem
- selecting, by the cloud-based service, a third storage subsystem to take over as a replication target of the dataset, and
- identifying, by the cloud-based service, a highest medium identifier (ID) of the dataset already stored on the third storage subsystem.
A non-transitory computer readable storage medium storing program instructions, wherein the program instructions are executable by a processor to:
- replicate a dataset from a first storage subsystem to a second storage subsystem;
- and
- responsive to detecting one or more conditions indicative of an impending failure of the first storage subsystem:
- generate and convey an alert from a cloud-based service to the second storage subsystem
- select, by the cloud-based server, a third storage subsystem to take over as a replication target of the dataset;
- and
- identify, by the cloud-based server, a highest medium identifier (ID) of the dataset already stored on the third storage subsystem.
