Nvidia 4 INITIALIZING, REBUILDING, AND SYNCHRONIZING RAID ARRAYS

CHAPTER

INITIALIZING, REBUILDING, ANDSYNCHRONIZING RAID ARRAYS

This chapter describes the following MediaShield tasks:

•Initializing a RAID Array

•Erase the data on the array by writing all zeros to the sectors of each hard disk.

•Rebuilding a RAID Array

•Rebuild a broken mirrored array

•Watch the progress of rebuilding of an array

•Only applies to RAID 1, RAID 0+1, and RAID 5 arrays

•Synchronizing a RAID Array

•Rebuild the redundancy in RAID 1 or RAID 0+1 arrays (copy the data to the

redundant disk—the same operation as rebuilding)

•Rebuild the parity in RAID 5 arrays
