Parameter
Volume Low Warning Threshold =
number
Purge Files On Dismount = value
Use to
Specify the number of blocks of free disk space that can remain
on a volume before the system issues a warning.
Supported values: 0 to 1000000 blocks
Default: 256 blocks
Consider the following: A block is the minimum space allocated to
a file.; a file can grow only in multiples of the block size.
The block's physical size is determined when the volume is
created. A volume can be assigned these block sizes: 4 KB, 8 KB,
16 KB, 32 KB, or 64 KB.
For example, if you enter 256 blocks for this parameter and the
volume's block size is 4 KB, the system warns you that the
volume is full when about 1 MB of space is left.
If your volumes are assigned different block sizes, each volume
has a different amount of free space when the warning is issued.
Have the system purge deleted files on a volume when it is
dismounted.
Supported values: ON, OFF
Default: OFF
