Case:
IBM Four Disk 146G SAS Disk, RAID damage
Solution:
1. For the current non -heat -reserve hard disk with a well -operating state, complete backup to a security storage with redundant functions, the hard disk that exists in physical problems must be restored according to the corresponding faulty type solution, and the maximum possibility of the fault is maximum.The data of the physical hard disk is also backup to safe storage 2. Analysis of all hard disk mirrors that have been fully backup currently backup to determine the original structural parameters of the fault RAID, and determine the offline status of each hard disk in the fault raid.The hard disk situation builds RAID data in only read the environment, and conducts a basic logical verification of the virtual RAID constructed to determine the general structure of the file system and generates a complete image of RAIDWith verification, if the file system in the mirror is still inconsistent, it is fixed according to the solution of the corresponding file system damage, until the data required by the customer is migrated until the customer needs the data required by the customer.
