RAID is a great system for increasing speed and availability of data as it offers more data protection than non-RAID disk systems. The management of the disks and the data distribution across them can be extremely complex.
No matter how well designed or implemented the system is, still there is one factor that causes problems to most RAID array and that is human being.
Why raid used?
RAID is a technology that is used to increase the performance and/or reliability of data storage. The abbreviation stands for Redundant Array of Inexpensive Disks. A RAID system consists of two or more drives working in parallel.

- Hard drives making clicking, grinding, or other abnormal noises
- Hard drive head crash
- Hard drive crashes
- Hard disk drive malfunction

Here is the list of general “Do’s” and “Don’ts” you need to know if you are using RAID-5 for data storage. If you’re reading this list for education, you’ll be wiser for the experience. If you’re already dealing with an emergency situation, do read on, but as you’ll see, it may be too late for some of the advice provided.
DO’s
- Fully document your storage array configuration during initial setup, including the physical arrangement and order of connection for all component devices, especially the disk drives.
- Maintain sequence of array members by tagging the physical disk drive units (not simply the tray the drive is mounted in) while everything is fully functional, and certainly, if trouble does arise, BEFORE any trouble-shooting begins.
- Test the subsystem’s ability to recover from a drive failure. With all data backed up, remove one of the drives from the subsystem while it’s running, and bring it back to full, undegraded operation using a blank hard drive replacement.
- Understand the fundamental concepts behind RAID-5 functioning, so that when any anomaly occurs remedies are always focused on preserving the data.
- Recognize that if as many as two hard drive elements have failed (that means any more than ONE), there is no possibility for regaining access to stored data without high-level data recovery expertise (call Micronics right away).
- Understand the distinctions between RAID-5 and other common levels of implementation, i.e., RAID-0, RAID-1, RAID-6, and RAID-10; knowing what your subsystem is NOT will help you understand better what it really is.
- Be familiar with any RAID subsystem manufacturer’s documentation and technical descriptions. At the same time, don’t rely on manufacturer service help to protect your data: their focus is on proper functioning of the equipment and they generally assume your data is backed up.
- Immediately replace a failed hard disk drive element upon fault detection; the replacement must be a pre-tested, known working device, fully conforming to subsystem designer specifications.
- Fully understand what “fault tolerance” really means in terms applicable to your specific subsystem, and always take action without delay to protect its full, complete functioning.
- When and if you begin in-house troubleshooting on failed RAID equipment, be meticulous and get assistance to document each and every remedial step taken.
- Know that rebuilding a RAID reporting a corrupted file system will not repair it, but further corrupt your data, possibly making it unrecoverable.
- As with all data storage, back up regularly!
DON’Ts
- Do not think of a RAID-5 as a data backup solution (it’s really only a scheme to increase data availability).
- Do not think of rebuilding a RAID-5 as a data recovery solution. Ideally you can read all data and have ensured a viable backup for the data contained on the subsystem is already saved before rebuilding.
- Never continue remedial actions after it becomes known that more than one disk drive has a fault; if this is the case you must seek professional data recovery help (call Micronics right away).
- Do not EVER attempt to rebuild a RAID unless ALL of the hard disk drive members are present, accounted for, confirmed to be fully functional individually, connected in the correct sequential order, and that the RAID controller also performs its POST and any other test routines flawlessly.
- Never ignore a RAID-5 data storage subsystem fault warning, or any behavioral anomaly; if a drive has failed, first back up the data in the array, then replace the drive, and then rebuild. Even though your data remains completely available, you are running in a degraded mode: the fault tolerance is lost immediately when one drive malfunctions. Limit your RAID degradation or loss of fault tolerance to the shortest reasonable time.
- Don’t remove more than one disk drive at a time from its mounted or physically installed position; this way you can’t lose track of the drive connection sequencing.
- Do not allow the RAID controller to execute write operations on any known working drives thus overwriting striping data needed for RAID-5 reconstruction.
- CHKDSK or the like should not be used, and if so, only with extreme caution; successful uses with RAID-5 are very limited; do not guess.
- Don’t try disk drives in different “slots” or shuffle the physical ordering of the array unless you are (and you probably cannot be) certain that the subsystem controller can recognize the changes; do not guess.
Don’t keep trying numerous “experiments” in efforts to bring inaccessible data back on line; call Micronics — rather than later.
