Sequential write management in accordance with the present description permits impermissible write retries to be processed by a hard drive such as a Shingled Magnetic Recording (SMR) hard dive. In one embodiment, logic returns a successful write indication in response to a received retry write request operation without writing data to the SMR hard drive if the data of the received retry write operation has already been successfully written to the same location requested by the received retry write request operation. Conversely, a failure notice is returned if the data of the received retry write request operation has not been previously successfully written to the same location requested by the received retry write request operation. Other features and aspects may be realized, depending upon the particular application.

Sequential write management in a data storage system

The present disclosure includes a method for migration of a first virtual function of a first device located on a PCI bus and accessible by a device driver using a virtual address. A second virtual function is created on a second device. A base address is determined for the second virtual function as a function of a logical location of the second device within the PCI structure. An offset is determined for the second virtual function as a function of the base address and the virtual address. The device driver is notified that the first virtual function is on hold. The offset is stored in a translation table. The device driver is notified that the hold has been lifted. Accesses to the virtual address and by the device driver to memory of the second virtual function are routed based upon the offset in the translation table.

There is set forth herein a computer program product, computing device, and method for displaying an email message. In one example, a computing device receives an input comprising at least one criterion for redacting email messages; stores the at least one criterion in a configuration of a client computer program; receives an email message having a field, the field comprising a first content; determines whether a condition of at least one of the email message and a current state of the computing device satisfies the at least one criterion stored in the configuration of the client computer program; and, in response to determining that the condition satisfies the at least one criterion, displays a second content in place of the first content in a user interface of the client computer program, wherein the second content is different than the first content.

Criterion-dependent email display agent

According to embodiments of the invention, methods, computer readable storage medium, and a computer system for determining a mapping mode for a DMA data transfer are disclosed. The method may include receiving a request for a DMA data transfer within a computer system. The method may also include determining a mapping mode for the DMA data transfer based on available system profile data in response to receiving the request. The method may also include mapping the memory using the determined mapping mode.

Determining a mapping mode for a DMA data transfer

Personal digital assistant devices are provided that query power subsystems to determine a level of battery power currently available for operating processes, and further determine a number of screen display changes that may be effected on a persistent display device at that determined level. If the determined number of screen display changes that may be effected at the determined level of available battery power fails to meet a specified minimum threshold number of images, the processing unit powers down subsystems of the personal digital assistant device and causes a highest listed image of a prioritized list of screen image instances to be displayed on the persistent display device, which persistently displays the image after a loss of power.

Persistent display of priority information on a portable electronic device

Illustrative embodiments include a method, system, and computer program product for estimating boot-time memory requirement of a data processing system. A data processing system identifies, using system configuration information associated with the data processing system, a set of components needed for booting up the data processing system. The data processing system determines a dependency of a component identified in the set of components, the component including a memory estimator program. The data processing system determines an ancestry of the component identified in the set of components. The data processing system receives, using the memory estimator program of the component, a boot-time memory requirement of the component. The data processing system calculates a total boot-time memory requirement. The data processing system determines whether an amount of real memory of the data processing system satisfies the total boot-time memory requirement.

Estimation of boot-time memory requirement

A system and method for network image propagation without a predefined network advantageously allows customers to automatically perform several system BOS installation or mksysb restoration over a virtual network with no predefined network and minimal installer configuration overhead. A method for network image propagation comprises: identifying a plurality of logical partitions residing in the logically partitioned terminal; configuring a temporary virtual network to connect said plurality of logical partitions to each other, wherein each one of the logical partitions is assigned at least one of a virtual Internet Protocol (IP) address and a virtual Media Access Control (MAC) address; installing an application image on at least one of the logical partitions via the temporary virtual network; deconfiguring the temporary virtual network; and assigning at least one of a physical IP address and a physical MAC address to said at least one logical partition on which the application has been installed.

System and method for network image propagation without a predefined network

A computer implemented method, apparatus, and computer program product for booting a computer using a boot list. A determination is made as to whether a boot list is present in a non-volatile memory of the computer. The boot list is a set of paths, in which each path in the boot list is a path of a storage device. If the boot list is not present, a search is performed for the boot list in a reserved area of each storage device in a set of storage devices. When the boot list is found in the reserved area of a storage device in the set of storage devices, the boot list is copied from the reserved area of the storage device in the set of storage devices to form a copied boot list. The copied boot list is stored in the non-volatile memory to form a stored boot list. The computer is booted using the stored boot list in the non-volatile memory.
