01209: Pct of Time Device Reserved 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:  Identify the system causing the reserve delay.

RATIONALE:  This measure reflects the actual time that a
reserve was in effect by one system, rather than the delay
that may have been incurred by another system that shares the
device measured by exception 1208.  However, if exception
1208 is reported in a complex of two or more systems, this
exception may identify the system causing the delay.

DEFINITION:  This exception is detected when the percent of
time a device was reserved exceeds the installation-defined
maximum.

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:

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

percent - The maximum percent of time a device is reserved is
specified.  A 5 percent threshold would appear as:
