Storage system, management server, and method of managing application thereof

Abstract

In a storage system having a plurality of disk array devices connected through a network to a host for running an application, and a management server for monitoring the disk array devices, the disk array device includes a physical disk error detecting unit for detecting an error in a physical disk. Meanwhile, the management server stores a corresponding relationship among the application, a logical volume used by the application, and the physical disk corresponding to the logical volume. Moreover, the management server includes an application detecting unit for detecting the application using the logical volume corresponding to the physical disk with the error according to the corresponding relationship when the physical disk error detecting unit of the disk array device detects the error in the physical disk.

         5 . A storage system according to  claim 3 , wherein said application processing capability allocating unit of said management server allocates the processing capability of said application according to operation input of a user.  
     
     
         6 . A storage system according to  claim 1 , wherein said management server at least includes applications detected by said application detecting unit, said disk array device used by said application, and an application information displaying unit for displaying application information concerning a processing capability allocated to said application on a screen of a display unit.  
     
     
         7 . A management server for monitoring a plurality of disk array devices connected through a network to a host for running an application and having a physical disk error detecting unit for detecting an error in a physical disk, wherein 
 said management server stores a corresponding relationship among said application, a logical volume used by said application, and said physical disk corresponding to said logical volume, and    said management server comprises:    an application detecting unit for detecting said application using a logical volume corresponding to said physical disk with said error according to said corresponding relationship when said physical disk error detecting unit of said disk array device detects said error in said physical disk.    
     
     
         8 . A management server according to  claim 7 , further comprising: 
 an application notifying unit for notifying a user terminal of information concerning said application detected by said application detecting unit.    
     
     
         9 . A management server according to  claim 7 , 
 wherein said corresponding relationship contains settings on priority of execution of a job of said application, and    said management server further comprises an application processing capability allocating unit for allocating a processing capability of said application according to said priority of execution of said job of said application which uses said physical disk with said error, when said physical disk error detecting unit of said disk array device detects said error in said physical disk.    
     
     
         10 . A management server according to  claim 9 , wherein the higher priority is given for execution of said job of said application using said physical disk with said error when said physical disk error detecting unit of said disk array device detects said error in said physical disk.  
     
     
         11 . A management server according to  claim 9 , wherein said application processing capability allocating unit allocates the processing capability of said application according to operation input of a user.  
     
     
         12 . A management server according to  claim 7 , further comprising at least: 
 applications detected by said application detecting unit, said disk array device used by said application, and an application information displaying unit for displaying application information concerning a processing capability allocated to said application on a screen of a display unit.    
     
     
         13 . A method of managing an application by a management server for monitoring a plurality of disk array devices connected through a network to a host for running an application, said method comprising: 
 allowing said management server to store a corresponding relationship among said application, a logical volume used by said application, and a physical disk corresponding to said logical volume, and    allowing said management server to detect said application using said logical volume corresponding to said physical disk with an error according to said corresponding relationship when said disk array device detects said error in said physical disk.    
     
     
         14 . A method of managing an application according to  claim 13 ,
