RAID failures can occur due to several reasons. But the real question is what you should do after data loss due to RAID failure. Generally, people have no idea what to do and what not to do.
As a result of which they applied their little knowledge which can worsen the whole situation. If you also want to know what to do and don’t do, then continue reading the article.
The Dos and Don’ts When Dealing with a RAID Failure
Here are five basic dos and don’ts when dealing with the RAID failure:
1. Make Additional Backup Offsite:
One of the things you have to do to avoid any problem in case of RAID failure is to keep the backup offsite. In most of the cases even when drives break RAID system keeps on working. However, the RAID system fails when issues arise in the second hard drive. Thus, it is essential to save your critical data at an offsite location. In this way, you won’t lose any of your data in case of the RAID failure. So, you can recover all your data easily from external hard drives, tapes or the cloud.
2. Quit Using RAID System:
RAID failure can provide a base for several other issues. Therefore, the moment you notice knowledge decline, any changes in your RAID or failures stop using it. This is a significant move to protect your data and avoid any severe impacts on your system. Because if you continue using your RAID system, it can worsen the problem and will overwrite knowledge. Therefore, avoid making the situation more terrible. Besides, don’t set up restoration computer software as it can also overwrite information worsening the situation instead of helping you.
3. Don’t Replace RAID Control:
One of the main reasons for the failure of the RAID system is the RAID control failure. The primary role of the RAID control is to manage and control all hard drives. Therefore, in case RAID control fails, it can strike the system. So, many people will consider replacing the defected RAID control with a new one. However, the problem is it cannot solve anything in reality and can lead the situation to greater danger. Therefore avoid replacing RAID control.
4. Don’t Replace Circuit Boards:
The RAID system consists of a series of hard drives. There are times when RAID fails due to the issues in the hard drives circuit boards. Therefore, when you confirm that its circuit boards are damaged then don’t try to replace them. Why, because not all the circuit boards are compatible with the system. Moreover, it is a risky option, as well. In case anything goes wrong will replace the circuits the whole situation will get worse, and it can permanently destroy all your data.
5. Avoid DIY Recovery:
Sometimes the reason for the data loss is the multiple hard drives failure. Therefore, at times when two or more hard drives fail to avoid using DIY raid data recovery. It is always better to take help from an expert. A single mistake during DIY recovery can cause the whole system to collapse. It can increase the extent of damages if you are confident and have experience then still before trying DIY methods to make an image for the server.
We have explained five things to do and avoid not to make the situation worse when RAID failure occurs.
