Disclosed systems and methods include or support a message logging service in which, responsive to receiving an event message generated by a business function, the message is logged in accordance with a message severity, one or more severity level attributes of the system, and one or more message logging criterion. Responsive to determining the message severity meets a first criterion, the message may be routed to and saved within a first persistent log file. Responsive to determining the message severity satisfies a second criterion, the message may be temporarily stored to a FIFO message queue, for possible inclusion in a second persistent log file. A health monitoring service for monitoring application programs corresponding to various business functions, upon detecting a degraded health state of a business function, may cause messages stored in the message queue to be dumped to a second persistent log file.

Techniques for managing data mobility domains in storage system environments. The techniques employ a multiple master approach, in which each storage system in a storage system domain can function as an owner of the domain. Each domain owner has privileges pertaining to addition of new members to the domain, removal of members from the domain, and modification of domain credentials. When a new storage system is added as a member of the domain, the domain credentials are provided from the domain owner to the new storage system, resulting in the domain credentials being shared among all members of the domain. Domain membership information is also shared among all members of the domain. In this way, the management of storage system domains can be achieved without the need of a domain management server, avoiding a single point of failure or latency and reducing the complexity/cost associated with the domain management server.

Systems and methods of serverless management of data mobility domains

A data protection technique involves, based on a first set of policies on a first storage array, generating a second set of policies on a second storage array to track the first set. The first array maintains a first storage object, and the second array maintains a second storage object as a replica of the first storage object. The technique further includes detecting assignment of the first set of policies to the first storage object and, in response to such detection, assigning the second set of policies to the second storage object. Application of a set of storage policies to a storage object may be delayed if the storage object is a replication destination. A policy group may identify multiple data protection rules or policies, which may include a snapshot rule and/or replication rule, and a user may be prevented from directly making a rule modification to a policy group. An orphan policy group cleanup operation may be performed to delete orphan policy groups.

A method is used in managing virtual systems in data storage systems. First and second virtual systems are managed. The first virtual system uses a first format for communicating with a data storage system and the second virtual system uses a second format for communicating with the data storage system. A universal virtual system management module of the data storage system is used for communicating with the first and second virtual systems. The universal virtual system management module communicates with the first virtual system by using a first virtual system handler configured to communicate based on the first format. The universal virtual system management module communicates with the second virtual system by using a second virtual system handler configured to communicate based on the second format.

Described are techniques for using a first secure communication connection between a first component and a second component to establish a second communication connection as another secure communication connection between the components. The first secure communication connection may be used to exchange fingerprints for digital certificates of the two components. The second communication may be used to exchange digital certificates of the two components. Each of the components may determine whether the received fingerprint of the other component matches a calculated fingerprint of the received certificate for the other component, and if so, the received certificate for the other component may be stored in a data store of said each component.
