Computer system and a program install method thereof

Abstract

A computer system including plural computers, a management console for installing a program in the computers and a storage subsystem coupled to each computer and management console. The storage subsystem includes a first storage unit shared by the computers and plural second storage units corresponding to the computers. The first storage unit stores a file related to each installed program and an installer program for installing a program. The second storage units each store an install agent and a control file accessed by the install agent. The management console includes an install manager for starting each install agent by switching on power to a corresponding computer. Upon starting, the install agent starts the installer program based on the control file. The installer program reads a related file from the first storage unit, and transfers it to the second storage unit of the corresponding computer, thereby installing the program.

1 . A method of installing a program in a first system comprising a first system including a first computer, a second computer, a management computer to be operated by an operator to install a program, and a storage subsystem coupled to said first and second computers, wherein said storage subsystem comprises a shared logical unit which is to be accessed from said first computer, said second computer, and said management computer, a first logical unit to be accessed from said first computer, and a second logical unit to be accessed from second computer, said method comprising:
 a step, by said storage subsystem, of providing, in response to a linking request from said management computer, a link for use in installing a program between said first and second logical units;   a step, by said storage subsystem, of reading, in response to a command from out of said storage subsystem, an installer program stored in said shared logical unit;   a step, by said storage subsystem, of executing said installer program to read out a program stored in said shared logical unit and storing said program in said first logical unit; and   a step, by said storage subsystem, of storing, in accordance with said link, said program in said second logical unit.   
   
   
       2 . A method of installing a program in a first system including a first computer, a second computer, and a first storage subsystem coupled to said first and second computers, wherein said first storage subsystem comprises a first logical unit to be accessed from said first computer, and a second logical unit to be accessed from said second computer, said method comprising:
 wherein there is provided apart from said first system a second system including a third computer, a second storage subsystem coupled to third computer, and a management computer coupled to said third computer and said second storage subsystem;   wherein there is provided, between said first and second storage subsystems, a data transferor for copying data between a logical unit of said first storage subsystem and a logical unit of said second storage subsystem;   a step, by said second storage subsystem, of providing a first shared logical unit, a third logical unit corresponding to said first logical unit, and a fourth logical unit corresponding to said second logical unit in said second storage subsystem;   a step, by said storage subsystem, of providing, in response to a linking request from said management computer, a link for use in installing said program between said third and fourth logical units;   a step, by said second storage subsystem, of reading, in response to a command received from out of said second storage subsystem, an installer program stored in said first shared logical unit;   a step, by said second storage subsystem, of executing said installer program to read out a program stored in said first shared logical unit and storing said program in said third logical unit;   a step, by said second storage subsystem, of storing, in accordance with said link, said program in said fourth logical unit;   a step, by said data transferor, of copying contents of said third logical unit into said first logical unit; and   a step, by said data transferor, of copying contents of said fourth logical unit into said second logical unit.
