How the Threshold field works

The Threshold field specifies the disk space threshold. If a write causes the quota target to exceed the threshold, the write still succeeds, but a warning message is logged to the storage system console and an SNMP trap is generated. This field is optional.

The following list describes the rules for specifying a value in this field:
  • K means 1,024 bytes, M means 2 to the 20th power or 1024 * 1024 bytes, and G means 2 to the 30th power or 1024 * 1024 * 1024 bytes.
    Note: The Threshold field is not case-sensitive. Therefore, you can use K, k, M, m, G, or g.
  • The maximum value you can enter in the Threshold field is one of the following values (equivalent to 16 TB):
    • 16,383G
    • 16,777,215M
    • 17,179,869,180K
    Note: If you omit the K, M, or G, Data ONTAP assumes a default value of K. The value cannot be specified in decimal notation.
  • The value in the Threshold field, if any, should be a multiple of 4 KB.

    If it is not, the Threshold field can appear incorrect in quota reports. This happens because the Threshold field is always rounded up to the nearest multiple of 4 KB to match disk space limits, which are translated into 4-KB disk blocks.

  • The Threshold field must be on the same line as the Disk field.

    Otherwise, the Threshold field is ignored.

  • If you do not want to specify a threshold for the quota target, enter a hyphen (-) in this field or leave it blank.
