01207: Pct of Time Device Not Ready Exceeds Max

FILE: Device Activity File
SAS FILE NAME: DAYS.HARDVA01
SOURCE LOCATION: prefix.MICS.USER.SOURCE(DYRMFEXC)

SEVERITY: Warning              (SEVERITY='W')
MANAGEMENT AREA: Performance   (MGMTAREA='PERFORMANCE')

PURPOSE:  The percent of time a device was not ready may be
used to identify when the device was not ready due to mounts
or problems on the device.

RATIONALE:  The percent of time that a mountable device is
not ready is a measure of the mount service time (as separate
from the mount queue time, the time required to recognize the
mount request and locate the volume), and thus provides
productivity measures.  For a non-mountable device, "device-
not-ready" indicates a problem with the device.

DEFINITION:  This exception is detected when the percent of
time device-not-ready exceeds the installation-defined
maximum.  Different values should be established for
different device classes and types.

EXCEPTION STATEMENTS:  The SAS statements identifying the
exception situation and describing the condition are stored
in the source member named in SOURCE LOCATION and are
described below:

** 01207 PCT OF TIME DEVICE NOT READY EXCEEDS MAX;
IF (DEVCLASS EQ 'TAPE' AND DVAPCNRD GT percent) OR
   (DEVCLASS EQ 'DASD' AND DVAPCNRD GT percent)
 THEN DO;

THRESHOLD MODIFICATION:  The user should modify the percent
value according to the following convention:

percent - The maximum percent of time a device is not ready
is specified.  A 25 percent threshold would appear as:
