Troubleshooting  39 

 

 

Effects of a hard drive failure 

When a hard drive fails, all logical drives that are in the same array are affected. Each logical drive in an 

array may be using a different fault-tolerance method, so each logical drive can be affected differently. 

•

 

RAID 0 configurations cannot tolerate drive failure. If any physical drive in the array fails, all 
non-fault-tolerant (RAID 0) logical drives in the same array will also fail. 

•

 

RAID 1+0 configurations can tolerate multiple drive failures as long as no failed drives are mirrored to 
one another (with no spares assigned). 

•

 

RAID 5 configurations can tolerate one drive failure (with no spares assigned). 

•

 

RAID 6 with ADG configurations can tolerate simultaneous failure of two drives (with no spares 
assigned). 

 

Compromised fault tolerance 

  

 

CAUTION: 

 When fault tolerance is compromised, data loss can occur. However, it may be 

possible to recover the data. For more information, see "Recovering from compromised fault 

tolerance (refer to "

Powering up

" on page 

21

)." 

  

If more drives fail than the fault-tolerance method can manage, fault tolerance is compromised, and the 

logical drive fails. If this failure occurs, the operating system rejects all requests and indicates unrecoverable 

errors. 
For example, fault tolerance might occur when a drive in an array fails while another drive in the array is 

being rebuilt. 
Compromised fault tolerance can also be caused by problems unrelated to drives. In such cases, replacing 

the physical drives is not required. 

 

Recovering from compromised fault tolerance 

If fault tolerance is compromised, inserting replacement drives does not improve the condition of the logical 

volume. Perform the following procedure to recover data: 

1.

 

Check for loose, dirty, broken, or bent cabling and connectors on all devices. 

2.

 

Power down the D6000 ("

Power down

" on page 

21

). 

3.

 

Power up the D6000 ("

Powering up

" on page 

21

). 

In some cases, a marginal drive is operational long enough to allow backup of important files. 

4.

 

Make copies of important data, if possible. 

5.

 

Replace any failed drives ("

Hard drive

" on page 

23

). 

 

Factors to consider before replacing hard drives 

You can replace hard drives without powering down the system. However, before replacing a degraded 
drive:
