Problems solved by technology

Therefore, when configuration changes, software upgrades, etc. cause software unavailability or system crashes (system panic), or other reasons cause system crashes, for example, in the following scenarios: (1) The user uses the storage device supplier The latest software information is a non-destructive (NDU) upgrade of the software. During the NDU process, changes to the driver and software may cause the system to crash or fail to restart or some software may not be available; (2) the user Perform new configurations on certain software, resulting in system downtime or software unavailability; (3) As time goes by, the system itself accumulates errors that lead to system downtime, if the user cannot restart the storage device under these circumstances To solve the problems encountered and only to seek help from the storage device supplier, a lot of time may be wasted unnecessarily, and the system may not be restored in time, which may lead to major commercial losses
On the other hand, for the technical support personnel or engineers of the storage equipment supplier, it will also waste precious time unnecessarily

Abstract

The embodiment of the invention provides a method and device for fault recovery in storage equipment. The storage equipment comprises at least one server and a storage device, wherein a plurality of assemblies operate on the at least one server. The method comprises the following steps of performing backup on one or a plurality of assemblies in the plurality of assemblies operating on the at least one server in the storage device; monitoring the fault occurrence on the at least one server, and positioning the assembly causing the fault; obtaining one or a plurality of assemblies which are backed up in the storage device and correspond to the assembly causing the fault; and recovering the fault by the obtained one or the plurality of assemblies.

Description

technical field [0001] Embodiments of the present disclosure generally relate to the field of storage, and more particularly relate to methods and apparatuses for fault recovery in storage devices. Background technique [0002] Current storage devices, especially storage devices used as storage servers, do not support backup and restoration of control path data (control path data). For example, for some storage devices already on the market, such as EMC mid-range and high-end storage devices, there are parts with different functions, such as the operating system kernel running on the storage processor SP / control station server CS / data movement server DM , software and system configuration, and data related to operating status are not backed up. Therefore, when configuration changes, software upgrades, etc. cause software unavailability or system crashes (system panic), or other reasons cause system crashes, for example, in the following scenarios: (1) The user uses the stor...
