摘要： A method for performing a data exchange between an initiator and a receiver in a fiber channel protocol (FCP) is provided. A control flag is set in a write command to indicate the presence of an identifier. The identifier is copied into a command descriptor block (CDB) of the write command and appended to a data frame. The write command and data frame, including the identifier, is sent from the initiator to the receiver.

摘要： Provided are a method, system, and program for copying tracks between a primary controller and secondary controller. A track is received from the primary controller that is part of a copy job comprising a sequence of tracks to copy along with a sequence number of the received track and a context number identifying computational resources in the primary controller used to transmit the track, sequence number, and context number. The context number and sequence number transmitted with the track are used to determine if a track preceding the received track was written to storage. The secondary-controller writes the received track to storage if the track preceding the received track was written to storage.
摘要翻译：提供了用于在主控制器和次控制器之间复制轨道的方法，系统和程序。从主控制器接收到作为复制作业的一部分的轨道，其包括要与所接收的轨道的序列号一起复制的轨道序列，以及识别用于发送轨道的主控制器中的计算资源的序列号，序列号和上下文编号。使用与轨道一起发送的上下文编号和序列号用于确定接收到的轨道之前的轨道是否被写入存储。如果接收到的轨道之前的轨道被写入存储器，则二级控制器将接收到的轨道写入存储器。

摘要： A method is disclosed to transfer information from a first information storage and retrieval system to a second information storage and retrieval system. The method provides a first information storage and retrieval system comprising a first track size and a plurality of first tracks, and a second information storage and retrieval system comprising a second track size and a plurality of second tracks. The method determines if the first track size is greater than the second track size. If the method determines that the first track size is greater than said second track size, then the method sets a ratio (R) equal to the first track size divided by the second track size, provides the (i)th first track from the first information storage and retrieval system to the second information storage and retrieval system, provides (R) second tracks, and maps the (i)th first track onto the (R) second tracks.

摘要： A method to provide information from a first information storage and retrieval system to a second information storage and retrieval system, where the first information storage and retrieval system comprises (N) PPRC adapters and information. The method generates and saves an Established Path Bitmap which recites the (N) PPRC adapters, and generates an Available Path Bitmap. If a PPRC adapter is in communication with the secondary storage system, then the method adds that adapter to the Available Path Bitmap. The primary information storage and retrieval system generates a PPRC task comprising a flag set to “off”. The method copies the Available Path Bitmap as a Working Bitmap, and generates a PPRC request comprising a flag set to “on”, selects one of the adapters recited in the Working Bitmap, and provides the PPRC request to that selected adapter. The method then once attempts to provide information to the second information storage and retrieval system using the selected adapter.
