Abstract: Various systems and methods for configuring and performing DR rehearsal operations. One method involves initiating a disaster recovery rehearsal for an application. The method involves generating a snapshot of a first storage element used by the application. The method also involves configuring a second storage element and starting an instance of the application. Starting the instance of the application utilizes the snapshot and the second storage element. Generating the snapshot, configuring the second storage element, and starting the instance of the application are performed in response to initiating the DR rehearsal.

Abstract: A computer-implemented method for proactively evaluating failover nodes prior to the occurrence of failover events may include (1) identifying at least one primary node that services at least one application, (2) identifying at least one failover node designated to service the application if the primary node were to fail, (3) prior to detecting failure of the primary node, proactively evaluating the failover node's ability to service the application if the primary node were to fail, and then (4) in response to determining that the failover node would be unable to adequately service the application if the primary node were to fail, proactively performing at least one corrective action that would cause the application to be adequately serviced if the primary node were to fail. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: A method and system for logical partition (LPAR) migration including creating a profile for a logical partition on a host system comprising one or more LPARs, wherein the profile is associated with a first name. Also, within the profile, a port of a client virtual small computer system interface (SCSI) adapter of the LPAR is mapped to a port of a server virtual SCSI adapter of a virtual input/output server (VIOS) of the host system. The server port of the VIOS is set to accept any port of virtual client SCSI adapters of the one or more LPARs of the host system. Within the VIOS, the server port of the VIOS is mapped to a device name (i.e., LPAR) and to a target device (i.e., a disk of shared storage), for purposes of proper failover implementation of the LPAR, wherein the target device comprises an operating system for the LPAR.
