Using Advanced Features of
RAID Admin
The advanced features of RAID Admin give you several
options as you work with RAID arrays.
With RAID Admin’s advanced features you can:
• Subdivide arrays into as many as six “slices”
• Merge multiple slices into one slice
• Expand array capacity by adding drives
• Verify or rebuild parity in a protected RAID array (RAID 3 and 5)
• Specify which arrays are visible on host systems (LUN masking)
Slicing an Array
You can subdivide a RAID array into segments, or slices. These slices are effectively
hardware partitions of all drives on the array. Each slice is a separate LUN and appears
as a separate volume on a host computer.
