This article introduces you how to easily solve the failure of IBM storage hard disk, the content is very detailed, interested friends can refer to, hope to be helpful to you.

IBM stores hard disk failure information:

1. The storage of an IBM DS5300, a machine head, four expansion cabinets connected, and the bottom layer is the RAID of a hard disk group of 50 600GB.

2. Two groups of RAID5, one group of RAID crashed, this set of RAID consists of 27 600G hard drives, stored in Oracle database files, a total of 11 volumes in the upper layer of the storage system, the volume size of 1TB has 10, one is 4TB.

IBM storage hard disk detection analysis:

The engineer first checked the hardware of the user's 27 hard drives and found that the user's 2 hard drives had bad tracks, and the error redundancy level of SMART had exceeded the threshold. 25 normal hard disks were fully mirrored, and 2 bad hard disks were restored with hardware tools and generated image files.

IBM storage failure analysis:

First collect the IBM DS5300 storage log information. From the indicator light of the hard disk on the storage, we can see that there are two disks with yellow lights. Analyze the log information collected and the offline time of the two hard drives, so as to know that the data in that hard disk is up-to-date, and use the hard disk with the latest data for data recovery.

IBM storage failure solution:

1. Mandatory online through IBM DS storage management software, backup all stored hard drives before mandatory online, and then forced online.

2. Through the analysis of the bottom data of the hard disk, the RAID reorganization is carried out, the data is extracted from the bottom, the oracle database is reloaded, and the upper application is debugged.

IBM storage failure implementation:

All the hard drives stored have been backed up, and problems can also be restored, so the first solution is first tested on the simulator, and then online on storage.

The raid is in a degraded state after being forced online by IBM DS storage management software. At this time, set up the hot spare and put it on top of the hot spare for data synchronization. After synchronization, the upper volume can be used directly, all the data can be seen, and the upper application can also be used normally.

IBM Storage failure data recovery results:

Because the upper volume can be used directly, the data is also visible, but because of the data security issues, we copy all the files in the volume and hand them over to the customer. The data has been checked and accepted by the user, and the data recovery work is completed.

On how to easily solve the IBM storage hard disk failure to share here, I hope the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
