Abstract: The invention provides for a method and corresponding Information Handling System (IHS) to protect storage systems from device discontinuity caused by misconfigurations. An embodiment of the IHS comprises a network switch coupled for communication to a storage group where a member of the storage group is a group leader. The group leader has access to configuration information for each member of the group and the network switch. The IHS further comprises an agent monitor that communicates a proposed change affecting the switch and/or a member of the group to the group leader. The group leader in response to the proposed change determines the acceptability of the proposed change using the accessed configuration information and in turn, communicates the determined acceptability to the agent monitor at the network switch. The agent monitor or the group leader then provides output indicating the acceptability of the proposed change to a network administrator.

Abstract: A system and method for providing automatic data restoration after a storage device failure are disclosed. An agent module detects a failure at a logical unit located at a primary storage device. The agent module locates backup data from the failed logical unit that is stored on a backup storage device and transfers the backup data from the backup storage device to a spare logical unit located on the primary storage device. The agent module then maps the spare logical unit to an address associated with a host in response to detecting the failure at the logical unit.

Abstract: A method and system for releasing a reservation held by a host on a target device is disclosed. The method includes determining if a reservation held by a host on a target device is releasable, and if so releasing that reservation upon failure of the host. The method may be used in any computer or information handling system.
