Abstract: A method, non-transitory machine readable medium, and system are provided for modifying a device-specific module (DSM) corresponding to a storage device. In some embodiments, the method includes registering a first device-specific module (DSM) with a Multipath I/O (MPIO) module. The MPIO module provides one or more interfaces of the first DSM that redirect to one or more interfaces of a second DSM. The second DSM is modified to a modified second DSM. The MPIO module accesses the one or more interfaces of the first DSM and the accesses are redirected, by the one or more interfaces of the first DSM, to one or more interfaces of the modified second DSM.

Abstract: Methods and systems for automatically identifying storage array modifications thereof. An interface device associated with a data-processing system and a storage array thereof can be automatically monitored in order to identify one or more command completion events associated with the interface device. Data indicative of the status of the interface device can then be automatically compiled in response to identifying the command completion even(s) as a result of automatically monitoring the interface device. Data indicating that the storage array has been modified can thereafter be generated if the data indicative of a status of the interface device is equivalent to a particular value.

Abstract: An apparatus and method for enhancing data availability by leveraging primary/backup data storage volumes. A Remote Volume Mirroring (RVM) system may be leveraged according to the present invention to provide volume failover by enhancing the functionality of the arrays, in a manner transparent to the host operating system.
