139Command Console V2.5 User Guide
read source For HS-series controllers, a mirrored virtual disk option that
controls the way data is read from the virtual disk's members.
There are two Read Source options:
■ Least Busy (default) -- the Normal, virtual disk member
with the smallest I/O load is the target of all read
operations.
■ Round Robin -- each Normal, virtual disk member is the
target of a read operation in sequential membership order.
No preference is given to any member.
rebuild rate The rate at which the controller reconstructs a failed device on a
spare. To devote more or fewer cycles to rebuilding a failed
device on a spare, adjust the rate using a scale from 1-100. A
rebuild rate of 100 rebuilds the device at the fastest rate
possible.
reconstructing A physical device state that indicates that the controller is
regenerating a failed device's data onto a replacement device
that is part of a redundant virtual disk.
All user data remains available during the reconstruction
process, but some performance reduction occurs if a request
requires access to a device while it is being reconstructed.
reconstruction Process of regenerating all of a failed member's data, writing it
to a spare device, and incorporating the spare device as a
redundant RAID virtual disk member.
All user data remains available during the reconstruction
process, but some performance reduction occurs if a request
requires access to a device while it is being reconstructed.
reconstruction rate The speed at which a failed member's data is regenerated. The
rate is adjustable. See rebuild rate.
reduced A virtual disk state that indicates that a member device is
missing, failed, or physically removed from a virtual disk.
redundant RAID Any RAID level that uses redundant information to provide
some level of data protection. RAID 1 (mirroring), RAID 0+1
(striped mirroring), RAID 3 (striped parity), RAID 5 (striped
parity), and RAID 3/5 (striped parity) virtual disks are all
examples of virtual disks that use redundant-RAID techniques.
