Case:
This HP storage is relatively old. The bottom layer is composed of 7 73G SCSI disks, of which 1 is a heat -preserved disk and the RAID data area is composed of 6 disks.Offline this HP storage collapse.
Solution:
This is just a normal RAID collapse due to the drop of multiple disks. After the data is lost, the administrator does not take some damaged rescue measures. This still maintains the originality of the accident scene.In most cases, the data recovery of 100 data recovers.At the scene of the accident, first of the 7 disks, the complete mirror image was performed. All the latter operations were not performed on the original disk of the customer to maintain the originality of the scene.It is easy to analyze the RAID structure, exclude the disk replaced by the heat, and then exclude a disk that has long been offline, virtual reorganization RAID, and the data is perfectly reproduced.
