RRAYS

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
