Storage Pool Attribute Set
MIRROR
specifies whether mirrored volumes are allowed in the storage pool. The following
are valid values:
The default value is ALLOWED.
DISKTHRESHOLD
specifies a threshold at which the disk processes associated with physical volumes
in the storage pool should emit an EMS disk-full event. A value of OFF disables
disk-full event emission. A value of 1 through 100 specifies the percentage of
allocated disk space used at which the event should be emitted. For example, a
value of 75 causes event emission when 75 percent of the space allocated for a
volume has been used. This parameter works in conjunction with the next
parameter to control the frequency of disk-full event emission. The default value is
OFF.
DISKINTERVAL
specifies a percent interval at which disk-full events should be generated after the
DISKTHRESHOLD value has been reached. This attribute has no effect when it
has a value of OFF. It also has no effect when the value of DISKTHRESHOLD is
OFF or when the sum of the values of the DISKTHRESHOLD and DISKINTERVAL
exceeds 100. A DISKINTERVAL value of 1 through 99 represents a specific
percent interval. For example, if a storage pool has a DISKTHRESHOLD of 75
percent and a DISKINTERVAL of 5 percent, an event is emitted when disk usage
reaches 75, 80, 85, 90, and 95 percent. The default value is OFF.
EXTENTTHRESHOLD
specifies a threshold at which the disk processes associated with physical volumes
in the storage pool should emit an EMS file-full event. A value of OFF or 0 disables
file-full event emission. A value greater than 0 represents the number of remaining
unallocated file extents in a file. For example, a value of 2 indicates that a disk
process should emit a file-full event when only 2 extents remain to be allocated to
a file. This parameter works in conjunction with the next parameter to control the
frequency of file-full event emission. The default value is OFF.
EXTENTINTERVAL
specifies an extent interval at which file-full events should be generated after the
EXTENTTHRESHOLD value has been reached. This attribute has no effect when
it has a value of OFF. It also has no effect when EXTENTTHRESHOLD is OFF or
Mirror State Meaning
D[ISALLOWED] A mirrored volume cannot be associated with the storage pool.
A[LLOWED] A mirrored volume can be associated with the storage pool.
R[EQUIRED] A volume must be mirrored before it can be associated with the
storage pool.
