Automatically creating multiple replication sessions in response to a single replication command entered by a user

A computer program product having a non-transitory computer readable medium which stores a set of instructions to perform replication, the set of instructions, when carried out by computerized circuitry, causing the computerized circuitry to perform a method of:

• receiving a virtual storage processor (VSP) replication command from a user, the VSP replication command specifying a source VSP and a destination VSP;
• identifying, in response to the VSP replication command, multiple source data objects which are configured to store data from the context of the source VSP;
• and
• after the multiple source data objects are identified, automatically creating multiple replication sessions to replicate the multiple source data objects as multiple destination data objects which are configured to store data from the context of the destination VSP,
• wherein a configuration database holds multiple VSP records corresponding to multiple VSPs,
• wherein identifying the multiple source data objects includes (i) locating, from the configuration database, a set of VSP records corresponding to the source VSP and (ii) ascertaining, from the set of VSP records, the multiple source data objects which are configured to store data from the context of the source VSP,
• wherein the multiple source data objects which are configured to store data from the context of the source VSP include multiple file systems,
• wherein the set of VSP records corresponding to the source VSP includes an identifier of each of the multiple file systems and a set of host interfaces through which the multiple file systems are accessed,
• wherein ascertaining the multiple source data objects includes constructing a list of lower-deck files from the set of VSP records, each lower-deck file on the list being one of the multiple source data objects,
• wherein at least some lower-deck files contain upper-deck file systems of upper-deck files;
• and
• wherein the method further comprises, prior to creating the multiple replication sessions, mounting the upper-deck file systems to a root file system of the source VSP.

An electronic apparatus, comprising:

• memory;
• and
• control circuitry coupled to the memory, the memory storing instructions which, when carried out by the control circuitry, cause the control circuitry to:
• receive a virtual storage processor (VSP) replication command from a user, the VSP replication command specifying a source VSP and a destination VSP,
• identify, in response to the VSP replication command, multiple source data objects which are configured to store data from the context of the source VSP, and
• after the multiple source data objects are identified, automatically create multiple replication sessions to replicate the multiple source data objects as multiple destination data objects which are configured to store data from the context of the destination VSP,
• wherein a configuration database holds multiple VSP records corresponding to multiple VSPs,
• wherein the control circuitry, caused to identify the multiple source data objects, is further caused to (i) locate, from the configuration database, a set of VSP records corresponding to the source VSP and (ii) ascertain, from the set of VSP records, the multiple source data objects which are configured to store data from the context of the source VSP,
• wherein the multiple source data objects which are configured to store data from the context of the source VSP include multiple file systems,
• wherein the set of VSP records corresponding to the source VSP includes an identifier of each of the multiple file systems and a set of host interfaces through which the multiple file systems are accessed,
• wherein the control circuitry constructed and arranged to ascertain the multiple source data objects is further constructed and arranged to construct a list of lower-deck files from the set of VSP records, each lower-deck file on the list being one of the multiple source data objects,
• wherein at least some lower-deck files contain upper-deck file systems of upper-deck files;
• and
• wherein, prior to creating the multiple replication sessions, the control circuitry is further constructed and arranged to mount the upper-deck file systems to a root file system of the source VSP.
