An administrator is experiencing a significant reduction of I/O performance. After issuing the
WRKDSKSTS command and pressing Fl 1 some of the disks in the list show “DEGRADED” rather
than “ACTIVE”.
Why are some of the disks in “DEGRADED” status?

A.
One of the disks in the RAID set has failed.

B.
Other devices which share the I/O bus are currently very busy.

C.
Read/write cache has been disabled on those disks for some reason.

D.
High ambient temperature has forced the drives to temporarily run slower.
