Adaptec SATA RAID FOR Manual page 43

Glossary
T
task
An operation that occurs only on the RAID controller,
asynchronous to all other operations; for example, initializing a
disk or verifying an array. Some tasks can take an extended period
of time, particularly if the RAID controller is also performing
intensive data I/O while the task is running.
V
verify
Low-level check that a drive, logical device, or hot spare is good. In
a RAID 1, verify is a low-level check that contents of both
members' segments are consistent and, optionally, corrects errors
while assuming that the master drive is correct. In a simple
volume, verify performs a low-level check that the whole drive can
be read.
volume
See simple volume, spanned volume.
