Abstract
(EN)
A method for processing a hard disk identifier duplication, comprising: obtaining a first preset number of first disk identifiers in a rear chip in a rear back board and a second preset number of second disk identifiers in a cascaded chip in a cascaded back board, wherein the first preset number is the number of hard disks managed by the rear back board, and the second preset number is the number of hard disks managed by the cascaded back board; if a duplication occurs in the first disk identifiers and the second disk identifiers, generating a second preset number of third disk identifiers different from all the first disk identifiers; and modifying the second preset number of second disk identifiers in the cascaded chip in the cascaded back board into the second preset number of third disk identifiers by using a preset language. There is no duplicate disk identifier in the disk identifiers managed by the cascaded back board and the rear back board, so that no erroneous data would be read, thereby eliminating potential safety hazards caused by a data reading error. An apparatus and system for processing a hard disk identifier duplication have the same beneficial effects as those of the processing method above.
(FR)
Procédé de traitement d'une duplication d'identifiant de disque dur consistant à : obtenir un premier nombre prédéfini de premiers identifiants de disque dans une puce arrière dans une carte de support arrière et un second nombre prédéfini de deuxièmes identifiants de disque dans une puce en cascade dans une carte de support en cascade, le premier nombre prédéfini étant le nombre de disques durs gérés par la carte de support arrière, et le second nombre prédéfini étant le nombre de disques durs gérés par la carte de support en cascade ; si une duplication se produit dans les premiers identifiants de disque et les deuxièmes identifiants de disque, générer un second nombre prédéfini de troisièmes identifiants de disque différents de tous les premiers identifiants de disque ; et modifier le second nombre prédéfini de deuxièmes identifiants de disque dans la puce en cascade dans la carte de support en cascade dans le second nombre prédéfini de troisièmes identifiants de disque à l'aide d'une langue prédéfinie. Il n'y a pas d'identifiant de disque dupliqué dans les identifiants de disque gérés par la carte de support en cascade et la carte de support arrière, si bien qu'aucune donnée erronée ne serait lue, ce qui permet d'éliminer les risques potentiels de sécurité provoqués par une erreur de lecture de données. Un appareil et un système de traitement d'une duplication d'identifiant de disque dur présentent les mêmes effets bénéfiques que ceux du procédé de traitement ci-dessus.

一种硬盘盘符重复问题的处理方法,包括获取后置背板中的后置芯片内的第一预设数目的第一盘符以及级联背板中的级联芯片内的第二预设数目的第二盘符,其中,第一预设数目为后置背板管理的硬盘数,第二预设数目为级联背板管理的硬盘数;当第一盘符与第二盘符存在重复的情况时,生成不同于所有的第一盘符的第二预设数目的第三盘符;采用预设语言将级联背板中的级联芯片内的第二预设数目的第二盘符修改为第二预设数目的第三盘符。级联背板与后置背板管理的硬盘不会存在重复的盘符,便不会读取错误的数据,消除了由数据读取错误产生的安全隐患。一种硬盘盘符重复问题的处理装置及系统,具有如上处理方法相同的有益效果。
