摘要:
An apparatus and system are provided for communicating control messages between a first device and a second device. The apparatus and system include a communication module that directs control messages between a first device and a second device through an intermediate device. The intermediate device is coupled to the first device by a control path and to the second device by a data path. The apparatus and system also include a translation module and a transmission module that cooperate to translate control messages received over the control path at the intermediate device to transport data messages and transport data messages received over the data path at the second device to control messages. Transport data messages are sent over the data path to the second device and control messages from the second device are sent over the control path to the first device.

摘要:
A system, method and article of manufacture are provided for the automatic recovery from errors encountered during an automated Licensed Internal Code (LIC) update on a storage controller. The present invention functions with a concurrent or nonconcurrent automated LIC update. The automated recovery from many error conditions is transparent to the attached host system and on-site service personnel, resulting an improvement in the LIC update process.

摘要:
A system, method and article of manufacture are provided to perform an automated concurrent licensed internal code (LIC) update and an automated nonconcurrent LIC update on a storage controller. The automated concurrent LIC update is performed on a storage controller by sequentially updating each cluster while maintaining operation of the storage controller. The automated concurrent LIC update allows multiple hosts to continue to access data via the storage controller while the system is actively undergoing the LIC update. The automated nonconcurrent LIC update is performed during the time the storage controller in not operating. The automated nonconcurrent LIC update allows service personnel to perform the update in an efficient and timely manner. When the update has completed, the storage controller becomes available to process data and the system is operating at the latest LIC level.
