摘要： A method, system, and computer program product provide a shared virtual memory space via a cluster-aware virtual input/output (I/O) server (VIOS). The VIOS receives a paging file request from a first LPAR and thin-provisions a logical unit (LU) within the virtual memory space as a shared paging file of the same storage amount as the minimum required capacity. The VIOS also autonomously maintains a logical redundancy LU (redundant LU) as a real-time copy of the provisioned/allocated LU, where the redundant LU is a dynamic copy of the allocated LU that is autonomously updated responsive to any changes within the allocated LU. Responsive to a second VIOS attempting to read a LU currently utilized by a first VIOS, the read request is autonomously redirected to the logical redundancy LU. The redundant LU can be utilized to facilitate migration of a client LPAR to a different computing electronic complex (CEC).

摘要： A method, system, and computer usable program product for migrating memory data between partitions are provided in the illustrative embodiments. All or a portion of a memory data of the source partition is written to a data storage unit, which may be a shared paging space, or a shared area of a data storage unit other than a paging space. The writing uses a first data communication path configured for paging the memory data. The portion of the memory data from the data storage unit is read at a destination partition. The reading uses a second data communication path configured for paging a second memory data. The read portion of the memory data may be used for executing a migrated application. The writing and reading may use a third and a fourth data communication paths respectively that may be configured for paging memory data to the shared area.

摘要： Disclosed is a computer implemented method, data processing system and computer program product to discover an SCSI target. The method comprises a client adapter transmitting an N_port ID virtualization (NPIV) login to a virtual I/O server (VIOS). The client adapter receives a successful login acknowledgement from the VIOS and issues a discover-targets command to the fabric. Upon determining that the SCSI target information is received, wherein the SCSI target information includes at least one SCSI identifier. Responsive a determination that SCSI target information is received the client adapter issues a port login to a target port, wherein the target port is associated with the at least one SCSI target. The client adapter makes a process login to form an initiator/target nexus between a client and at least one SCSI target. The client adapter queries the SCSI target by using a world wide port name associated with the target port.

摘要： A method utilizes cluster-awareness to effectively support a live partition mobility (LPM) event and provide recovery from node failure within a Virtual Input/Output (I/O) Server (VIOS) cluster. An LPM utility creates a monitoring thread on a first VIOS on initiation of a corresponding LPM event. The monitoring thread tracks a status of an LPM and records status information in the mobility table of a database. The LPM utility creates other monitoring threads on other VIOSes running on the (same) source server. If the first VIOS VIOS sustains one of multiple failures, the LPM utility provides notification to other functioning nodes/VIOSes. The LPM utility enables a functioning monitoring thread to update the LPM status. In particular, a last monitoring thread may perform cleanup/update operations within the database based on an indication that there are nodes on the first server that are in failed state.

摘要： Mechanisms are provided for an I/O virtualization management partition (IMP) to control the shared functionality of an I/O virtualization (IOV) enabled I/O adapter (IDA) through a physical function (PF) of the IOA while the virtual functions (VFs) are assigned to client partitions for normal I/O operations directly. A hypervisor provides device-independent facilities to the code running in the IMP and client partitions. The IMP may include device specific code without the hypervisor needing to sacrifice its size, robustness, and upgradeability. The hypervisor provides the virtual intermediary functionally for the sharing and control of the IOA's control functions.

摘要： A “LUN Table” enables Logical Unit Number (LUN) mapping/masking within an Input/Output Virtualization IOV adapter included in a Serial Attached Small Computer System Interface (“SAS” or “Serial Attached SCSI”). A plurality of System Images (“SI”) share block storage through the SAS. The IOV adapter includes one or more Virtual Functions (VF), a Physical Function (PF), and a LUN Table within the PF. The VF allows each SI to communicate I/0 requests with a storage device through the PF. The LUN Table maps the I/0 requests to unique locations within the storage device. Each SI is isolated from all other SIs. Interference between each SI is avoided. A VIOS or a LUN mapping/masking SAN are not required. I/0 latency, processor overhead and storage cost are improved over prior LUN mapping/masking solutions.
