Abstract: When the boot monitoring unit receives, from a management server, a first boot response for a first boot request from a NIC1 of a managed server, a boot monitoring unit stores a receiving time of the first boot response. When the boot monitoring unit receives a second boot request from a NIC2 of the managed server, and when a predetermined time has not elapsed from the receiving time, the boot monitoring unit determines that the management server is normal, and transmits an NOP program to the managed server. When the predetermined time has elapsed from the receiving time, the boot monitoring unit determines that the management server is stopped, and transmits a recovering program to the managed server.

Abstract: A storage device in which the MR-IOV is applied to an internal network of a storage controller. Data path failover can be executed in the storage device. The internal network of the storage controller is configured to enable the access of a virtual function (VF) “VF 0:0, 1” of each endpoint device (ED0-ED2) from a root port RP0. Likewise, “VF 1:0, 1” of each endpoint device can be accessed from a root port RP1. In a first data path from the RP0 to ED0 in a normal state, “VF 0:0, 1” and “MVF 0, 0” are connected by VF mapping. When a failure occurs on the first data path, the MR-PCIM executes the VF migration, whereby in the second data path from the RP1 to ED0, “VF 1:0, 1” and “MVF 0, 0” are connected by VF mapping. As a result, failover to the second data path is realized.

Abstract: A failed link is detected between a first SAS expander and a device. A data transfer of the first SAS expander connected to the device via the failed link is re-routed to a second SAS expander connected to the device via a functional link. The first SAS expander is connected to the SAS expander via the phys of the first SAS expander and the phys of the second SAS expander for inter-expander communications.

Abstract: A system and method for recovering from logical path failures is set forth. More specifically, when a host detects a logical path failure, the host enters a path discovery mode of operation. If the host continues to detect a logical path failure while operating in the logical path discovery mode of operation, the host removes the logical path from a logical path mask, and the host does not use the removed logical path again. Additionally, the system and method facilitates recovery of the failed logical paths by using a plurality of logical path masks. A first mask is referred to as an intermediate failure logical path mask and a second mask is referred to as a permanent failure logical path mask.

Abstract: A system and method for recovering from a single logical path failure. More specifically, although a host has not grouped its logical paths, the host knows which logical paths it has available. When a host detects a logical path failure, the host enters a path discovery mode of operation. If the host continues to detect a logical path failure while operating in the logical path discovery mode of operation, the host removes the logical path from a logical path mask, and the host does not use the removed logical path again. In the case of ungrouped logical paths, the host aborts its process because it does not have more paths available to continue its process. Additionally, in certain embodiments, a pseudo path group for ungrouped logical paths is created.

Abstract translation: 用于从单个逻辑路径故障恢复的系统和方法。 更具体地说，尽管主机没有对其逻辑路径进行分组，但主机知道其可用的逻辑路径。 当主机检测到逻辑路径故障时，主机将进入路径发现操作模式。 如果在逻辑路径发现操作模式下主机继续检测到逻辑路径故障，则主机从逻辑路径掩码中删除逻辑路径，并且主机不再使用已删除的逻辑路径。 在未分组的逻辑路径的情况下，主机中止其进程，因为它没有更多可用的路径来继续其进程。 另外，在某些实施例中，创建用于未分组的逻辑路径的伪路径组。
