Method for automatic updating of an access path to the system disk of a hardware perimeter of computer resources during launching of an operating activity on this perimeter, the perimeter being configured in a configurable system of computer resources adapted to:
- configure several perimeters intended to be activated simultaneously or successively, each perimeter including:
- a central processing unit formed by one or several calculation cells (30, 32, 34, 36) of a multi-cell computer platform (4),
- resources (8) common to the whole of the platform (4) of which at least a system disk (14, 16) is connected to the central processing unit via addressable means (6) for interconnection of the platform to the system disk (14, 16), and
- a working memory (48) containing the access path used during the activation of the perimeter in order to launch an operating system (24, 26) contained in the system disk (14, 16), this access path being composed of an upper part defining the hardware elements to be run through in order to reach the interconnection means (6) from the processing unit, this upper part being solely a function of the processing unit used in this perimeter, and a lower part defining the hardware elements to be run through in order to reach the system disk (14, 16) from the interconnection means (6), this lower part being solely a function of the position of the system disk (14, 16) with respect to the interconnection means (6),
- define an operating activity capable of being launched successively on several different perimeters, the activity bringing together software means to be utilised in order to carry out this activity, these software means including at least one operating system capable of managing the hardware resources of the perimeter on which the activity is to be launched, wherein the method includes:
- during the installation of a new system disk, a step (160) of saving the lower part of the access path to the new system disk in a list (70) of access paths stored in a memory (64),
- on the occasion of the definition of the operating activity, a step (180) of associating with this activity the lower part, stored in the list (70) of access paths, corresponding to the system disk including the operating system launched during this activity,
- on the occasion of the launching of the activity on a perimeter, a step (150) of automatic updating of the access path contained in the working memory (48) of this perimeter by combining the upper part of the access path of this perimeter with the lower part of the access path associated with this activity during its definition.
