摘要： A method for managing storage space in a storage port queue includes establishing a watermark for the storage port queue. The method further receives, at the storage port associated with the storage port queue, a command having an initiator-target-LUN (ITL) nexus associated therewith. Upon receiving the command, the method determines whether the used space in the storage port queue has reached the watermark. In the event the used space has not reached the watermark, the method processes the command. In the event the used space has reached the watermark and a specified number of commands for the ITL nexus are already present in the storage port queue, the method rejects the command. Otherwise, the method may process the command. A corresponding apparatus and computer program product are also disclosed herein.

摘要： A method, system, and computer program product to preserve data integrity in a mirror and copy environment is disclosed herein. In one embodiment, a method may include receiving a write command and data from a host device. The method may further include writing the data to a primary storage device and attaching a primary sequence number associated with the primary storage device to the write command, thereby providing a numbered write command with a command sequence number. The numbered write command may then be transmitted to a secondary storage device. The method may further include comparing the command sequence number to a secondary sequence number associated with the secondary storage device. If the command sequence number matches the secondary sequence number, then the command may be executed. Otherwise, it may be ignored.

摘要： A method for dynamically enabling and disabling use of XFR_RDY is disclosed herein. In one embodiment of the invention, such a method includes receiving a write command at a target and determining whether XFR_RDY is enabled or disabled for the write command. In the event XFR_RDY is disabled, the method determines whether one or more buffers are available at the target. If at least one buffer is available, the method processes the write command by writing data associated with the write command to the one or more buffers. The method then returns information indicating the number of buffers that are still available at the target after completing the write command. A corresponding apparatus and computer program product are also disclosed and claimed herein.
摘要翻译：本文公开了一种用于动态地启用和禁用XFR_RDY的方法。在本发明的一个实施例中，这种方法包括在目标处接收写入命令，并确定写入命令是否启用或禁用XFR_RDY。在XFR_RDY被禁用的情况下，该方法确定目标是否有一个或多个缓冲区可用。如果至少有一个缓冲区可用，该方法通过将与写入命令相关联的数据写入一个或多个缓冲器来处理写入命令。该方法然后在完成写命令之后返回指示目标上仍然可用的缓冲器的数量的信息。本文还公开并要求对应的装置和计算机程序产品。

摘要： An I/O device obtains multiple unique N_Port IDs (identifiers) for a NPIV N_Port ID Virtualization (NPIV) capable physical adapter. Fabric management routines are able to assign the multiple unique N_Port IDs to distinct fabric zones. LUNs (logical unit numbers) are able to be associated with the multiple unique N_Port IDs such the LUNs associated with unique N_Port ID do not exceed a limitation. The I/O device is able to associate different resources with different unique N_Port IDs to limit the scope of actions of one or more hosts. The I/O device is able to configure one or more LUNs by the multiple unique N_Port IDs to control access. Different unique N_Port IDs are able to be configured to have different quality of service attributes and/or different levels of security. The I/O device may include multiple independent logical partitions (LPARs) and assign each multiple unique N_Port IDs.

摘要： Provided are a computer program product, system, and method for processing a read operation for a target block of data. A read operation for the target block of data in target storage is received, wherein the target block of data is in an instant virtual copy relationship with a source block of data in source storage. It is determined that the target block of data in the target storage is not consistent with the source block of data in the source storage. The source block of data is retrieved. The data in the source block of data in the cache is synthesized to make the data appear to be retrieved from the target storage. The target block of data is marked as read from the source storage. In response to the read operation completing, the target block of data that was read from the source storage is demoted.

摘要： Provided a computer program product, system, and method for cache management of tracks in a first cache and a second cache for a storage. The first cache maintains modified and unmodified tracks in the storage subject to Input/Output (I/O) requests. Modified and unmodified tracks are demoted from the first cache. The modified and the unmodified tracks demoted from the first cache are promoted to the second cache. The unmodified tracks demoted from the second cache are discarded. The modified tracks in the second cache that are at proximate physical locations on the storage device are grouped and the grouped modified tracks are destaged from the second cache to the storage device.

摘要： Provided are a computer program product, system, and method for using an attribute of a write request to determine where to cache data in a storage system having multiple caches including non-volatile storage cache in a sequential access storage device. Received modified tracks are cached in the non-volatile storage device integrated with the sequential access storage device in response to determining to cache the modified tracks. A write request having modified tracks is received. A determination is made as to whether an attribute of the received write request satisfies a condition. The received modified tracks for the write request are cached in the non-volatile storage device in response to determining that the determined attribute does not satisfy the condition. A destage request is added to a request queue for the received write request having the determined attribute not satisfying the condition.
