• Only Media Scan is selected: The media scan operation scans
each drive starting at the lowest port. If all the drives have been
scanned and there is time remaining, the operation begins scan-
ning the lowest port again and continues until the scheduled time
completes.
• Verify and Media Scan are selected: Both tasks run sequentially
within the scheduled window. If the scheduled duration is four
hours, the verification operation is run during the first two hours
and the media scan operation follows during the remaining two
hours. If the duration is only one hour, only the verification
operation is performed.
• Rebuild/Initialize, Verify, and Media Scan are selected: If all
three operations are selected and a rebuild/initialize operation is
required, the rebuild/initialize operation is performed first. If
this operation completes within the first two hours of the win-
dow, a verification operation starts. If the rebuild/initialize oper-
ation completes in the last two hours of the window, the media
scan operation starts.
