Warning Threshold Low threshold for the
amount of space used in
this storage class. For disk
this is the percentage of
total space used. For tape
this is the number of free
VVs remaining. Alarms
will be sent to SSM
periodically when this
threshold is exceeded, and
the Space Thresholds
field on the HPSS Health
and Status window will
be changed to Warning.
Note that this field may be
overridden for specific
storage subsystems.
For disk, any integer percentage
between 1 and 100 (inclusive)
which is less than or equal to the
Critical Threshold. For tape, any
non-negative integer VV count
which is greater than or equal to the
Critical Threshold. Note: The
threshold for a disk class may be
disabled by setting this value to 100
percent. The threshold for a tape
class may be disabled by setting
this value to zero.
Disk: 80,
Tape: 10
