Abstract: A method to issue a statesave command from a host system to attached storage is provided. The attached storage is monitored for a predetermined threshold time to identify an inaccessible device. Upon expiration of the predetermined threshold time, the statesave command is issued from a device driver of the host system to the attached storage.

Abstract: An approach to handling connection errors between an external antivirus server and a storage device is disclosed. The storage device is equipped with an internal antivirus server. Antivirus metadata that describes the antivirus scan is stored in an antivirus metadata repository on the storage device. The connection between the external antivirus server and the storage device is monitored. The external antivirus server executes the antivirus scan on the storage device. If the connection fails, control of the antivirus scan is passed from the external antivirus server to the internal antivirus server. The internal antivirus server determines where to begin based on the antivirus metadata. When the connection is restored, control is passed back to the external antivirus server.

Abstract: A method for upgrading microcode in a multi-module storage system may include selecting a first module from two or more modules and operating the first module using an upgraded microcode. The method may include monitoring the performance of the first module by a second module of the two or more modules and rendering an indication of performance of the first module. Further, the method may include determining whether the indication of performance of the first module is greater than or equal to a performance metric.

Abstract: For file scanning, a division module divides a file into plurality of subfiles. An access module maintains a status of each subfile and scans each subfile with a separate server.

Abstract: 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.

Abstract: An apparatus, system, and method are disclosed for maintaining asynchronous mirroring. A detection module detects insufficient storage space to store a snapshot of a logical volume in at least one of a primary storage system and a secondary storage system. The primary storage system comprises the logical volume. A write from a host to the logical volume is acknowledged, maintaining asynchronous mode mirroring between the primary storage system and the host. The mirror module mirrors the write to the logical volume at the secondary storage system using a backup synchronous mode in response to detecting the insufficient storage space. Under the backup synchronous mode, the primary storage system acknowledges the write to the host while concurrently mirroring the write to the secondary storage system. The secondary storage system acknowledges the mirrored write to the primary storage system.

Abstract: Systems, methods, and computer program products for providing operating system (O/S) redundancy in a computing system are provided. One system includes a host computing device, a plurality of memory devices, and a sub-loader coupled between the host computing device and the plurality of memory devices. Each memory device stores a respective O/S and the sub-loader is configured such that the plurality of memory devices appear transparent to the host computing device. One method includes designating, a first logical unit device as a primary logical unit device and subsequently determining that the first logical unit device is unresponsive. The designation is removed from the first logical unit device and a second logical unit device is designated as a new primary logical unit device. One computer program product includes instructions for performing the above method.

Abstract: A method for distributing drivers from a storage system to one or more host systems includes maintaining, in a storage system, a driver database containing drivers for different host systems. The drivers enable the different host systems to effectively communicate with the storage system. The method further determines whether a specific host system is configured with an appropriate driver. In the event the specific host system is not configured with the appropriate driver, the method retrieves the appropriate driver from the driver database. The method then transmits the appropriate driver from the storage system to the specific host system for installation thereon. By using the storage system as a central repository for the latest device drivers, the method ensures that connected host systems are always configured with the latest drivers. A corresponding apparatus, system, and computer program product are also disclosed herein.
