RAID5 How to recover a single block and multiple hard drive failures

RAID5 is a relatively common disk array, with relatively high fault tolerance, won everyone's favorite. Although the RAID5 fault tolerance is very high, but also encountered a failure, the following to share the experience of RAID5 single block and multiple hard disk failure how to recover and hard disk data recovery method.

RAID5 single-Block Hard drive recovery method:

A single hard drive fails, and we plug it in by hot-swapping and plugging it in. If hot plug is not used to enter the RAID configuration interface, the hard disk is Forceonline operation. You can also change other hard drive slots by remembering not to disrupt the disk order. If the above action does not resolve the problem, try to format the hard disk after you insert it, and then use the Rebuild action. In this process, you may encounter an inability to format, because the hard disk physical error is serious, you should replace the hard disk after rebuilding data to solve the problem.

To replace the hard drive note:

1: Before replacing the damaged hard drive, be sure to check the current status of the array to ensure that the normal hard drive is online.

2: You cannot plug any hard disk before the array data is rebuilt. To complete the operation quickly and timely.

RAID5 multiple Hard Drive recovery method:

The first part of the hard drive on the line, in the operating system to try to read the data, in the case of reading, then the other hard drive online, and finally rebuild the data. If the damage to the SCSI card causes the configuration information to be lost, after the card is replaced, try to read the configuration information from the hard disk. After all the disks are on-line, the operating system may be unable to access the raid, view the array status in Computer Management and Disk Management, or, in the uninitialized state, try using the top data recovery software of the Shanghai Day Shield Data Recovery Center to scan the data by track to recover Be sure not to perform RAID initialization operations.
