CHAPTER 3 Using the NVRAIDMAN Utility More About Rebuilding Arrays • Rebuilding Occurs in the Background The rebuilding process takes some time to complete, and occurs in the background so as not to affect the performance of the system. • Rebuilding Applies Only to RAID 1 or RAID 0+1 Arrays Rebuilding an array works only when using RAID 1 and/or RAID 0+1. Rebuilding does not apply to RAID 0 and JBOD arrays. • Rebuilding applies to a degraded fault tolerant array You can rebuild a degraded mirrored array using any available Free Disk or Dedicated Disk. For example, Figure 3.22 shows a mirrored array using two 34.48 GB drives while having two Free Disks each 55.90 GB large. Figure 3.22 Free Disks Available for Rebuilding To use one of these available free disks to rebuild your array, follow the same steps as explained in "Rebuilding a RAID Array" on page 47, except when prompted to select a disk, choose one of the two available free disks.

More About Rebuilding Arrays
•
Rebuilding Occurs in the Background
The rebuilding process takes some time to complete, and occurs in the background so
as not to affect the performance of the system.
•
Rebuilding Applies Only to RAID 1 or RAID 0+1 Arrays
Rebuilding an array works only when using RAID 1 and/or RAID 0+1. Rebuilding does
not apply to RAID 0 and JBOD arrays.
•
Rebuilding applies to a degraded fault tolerant array
You can rebuild a degraded mirrored array using any available Free Disk or Dedicated
Disk.
For example,
Figure 3.22
shows a mirrored array using two 34.48 GB drives while
having two Free Disks each 55.90 GB large.
Figure 3.22
Free Disks Available for Rebuilding
To use one of these available free disks to rebuild your array, follow the same steps as
explained in
“Rebuilding a RAID Array” on page 47
, except when prompted to select a
disk, choose one of the two available free disks.
