RAID Server Failure:
A RAID server failure can take place for many reasons. Most RAID server failures are typically attributed to a logical RAID server failure. However, a physical RAID server failure can also cause a logical RAID server failure or a failure of a NAS or SAN storage device.
Most of the RAID data recoveries we have seen are attributed to a logical RAID server failure. The best solution to avoid needing a RAID data recovery or server data recovery service is to have an excellent hardware and software maintenance plan in place.
A RAID server failure can be caused for many reasons. We have listed some RAID server failures below and how they may occur. Our findings are based on communication with potential clients requesting information on RAID data recovery services and questions about how to address their RAID failure.
How to Keep your RAID Server, NAS or SAN storage device Safe:
- Backup… Backup… Backup.
- Replace older hard drives every 2 to three years or as needed.
- Keep your server virus software up to date.
- Test your UPS battery and device.
- Perform routine server maintenance.
- Check your Server Operating system log.
- Check your backup logs.
Logical RAID Server Failure causes:
- You Re-initialized RAID array when there is still a RAID hard drive failure.
- A virus attack damaged the RAID striping.
- The RAID partition was formatted.
- A RAID partition is missing or went offline.
- RAID configuration lost or got corrupted.
- A RAID Software corruption occurred.
- You upgraded your server operating system.
- Server registry corrupted.
- Someone accidentally deleted server operating system files.
- A bad command was executed or written to your Linux server.
Hardware RAID Server Failures / Physical RAID Server Failures:
- The RAID controller card is failing.
- The server motherboard or other key component failed.
- Although rare, more than one hard drive failed at the same time.
- A loose controller cable.
- A hard drive failed and then a second drive failed.
- There was a hardware change to your server causing a RAID hardware incompatibility.
- A RAID server was physically damaged by water.
Server Power Issues + Other RAID Server Failures :
- An unstable electrical anomaly damaged the RAID Server, NAS or SAN device.
- Your UPS battery is bad and your server had a power issue.
