ξEnding Boundary

This field is valid in the MODE SENSE command. This field indicates the ending of the active notch or, if the active notch is zero, the ending of the logical unit (IDD).

ξPage Notch

This is a bit map which shows whether or not other mode pages are being changed if the device is notched. The most significant bit of this field corresponds to page code 3Fh and the least significant bit corresponds to page code 00h. If it is specified, the IDD disregards this value.

Figure 4.8 MODE SELECT parameters: informal exception control page

This page specifies whether the drive failure prediction function is enabled or disabled and the reporting method when a drive failure is predicted.

The log errors bit (LogErr) of zero indicates that the logging of informational exception conditions within a target is vendor specific. A LogErr bit of one indicates the target logs informational exception conditions.

A Test bit of one creates a false device failure at the next interval time, if the DExcpt bit is not set. When the Test bit is one, the MRIE and Report count fields apply as if the Test bit were zero. The
