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.

Various embodiments for managing data in a computing storage environment by a processor device are provided. In one such embodiment, by way of example only, an extender storage pool system is configured for at least one of a source and a target storage pool to expand an available storage capacity for the at least one of the source and the target storage pool. A most recent snapshot of the data is sent to the extender storage pool system. The most recent snapshot of the data is stored on the extender storage pool system as a last replicated snapshot of the data.

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.

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.

A method of automatic recovery from a boot device failure and an initial program load (IPL) failure of an operating system (OS) comprises: receiving and complying with a user selected option of an action upon an event of a boot device failure and an IPL failure. The user selected option may consist of taking the action of attempting an auto reboot of the server with the selected boot device and continuing the reboot attempts using the reduced priority boot devices from the bootlist until detection of a boot success, or taking no action allowing for manual user intervention.
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.
