    摘要: A method for identifying the cause of degraded I/O performance between a host system and a storage controller includes initially monitoring I/O performance between the host system and the storage controller. The method further detects degraded I/O performance between the host system and the storage controller using any suitable technique. Once degraded I/O performance is detected, the method determines the cause of the degraded I/O performance by analyzing historical configuration records in the storage controller. These historical configuration records enable the storage controller to correlate the degraded I/O performance with configuration changes in the storage controller and/or the connected host systems. The method then notifies one or more host systems of the cause of the degraded I/O performance. A corresponding apparatus and computer program product are also disclosed herein.

    摘要: A method, apparatus, and computer program product for handling a failure condition in a storage controller is disclosed. In certain embodiments, a method may include initially detecting a failure condition in a storage controller. The failure condition may be associated with a specific host and a specific storage device connected to the storage controller. The method may further include determining a failure ID associated with the failure condition. Using the failure ID, en entry may be located in a data collection and recovery table. This entry may indicate one or more data collection and/or recovery processes to execute in response to the failure condition. The method may then execute the data collection and/or recovery processes indicated in the entry. While executing the data collection and/or recovery processes, connectivity may be maintained between hosts and storage devices not associated with the failure condition.

    摘要: A mechanism is provided in a storage control unit in a data processing system for providing unsolicited global disconnect requests to users. The mechanism stores lock control data in the storage control unit. The storage control unit allocates its resources into a plurality of clusters. Responsive to a given user connecting to a given partition that is for a logical subsystem resident on a first cluster within the plurality of clusters, the mechanism sends reflected partition information from the first cluster to a second cluster within the plurality of clusters. Responsive to the first cluster experiencing a failure condition, the mechanism moves control data from one or more logical subsystems from the first cluster to the second cluster and for each logical subsystem that moved from the first logical subsystem to the second logical subsystem and that has reflected partition information, presents unsolicited status to one or more users.

    摘要: An apparatus, system, and method for generating an advanced function usage planning report. One embodiment of the apparatus includes a detection module, a monitoring module, and a planning report module. The detection module detects use of an advanced function on a storage controller. The advanced function includes an optional storage function beyond a standard function set. The monitoring module monitors the use of the advanced function on the storage controller. The planning report module generates a planning report based at least in part on use information from the monitored use of the advanced function.

    摘要: An initial program load (IPL) of a logical partition (LPAR) is managed by establishing a logical path to the LPAR from a storage controller. When a notice is received by the storage controller from the LPAR that the IPL has commenced, the LPAR address is stored in a data structure. After the storage controller initiates a pack change state interrupt, the stored address is compared with the addresses in a list of all LPARS to which the interrupt is directed. If the list of addresses includes the stored address, the stored address is removed from the list. Thus, the pack change state interrupt is transmitted only to the addresses in the list, leaving the LPAR to complete the IPL without interruption. After the storage controller receives a notice from the LPAR that the IPL has completed, the address of the LPAR is removed from the data structure.

    摘要: An enterprise network interface client application and a local, central electronic complex (CEC) in a dual CEC environment implement an alternative method of communication. Upon a send failure of a command to a first CEC in the environment, the command is sent to a second CEC using a CEC to CEC message mechanism. A method of communicating an asynchronous event is implemented between a microcode layer and an enterprise network interface client application in a dual central electronic complex (CEC) environment. A copy of the event is retained. Upon a send failure of the event to a first CEC in the environment, the copy of the event is sent to a second CEC in the environment.
