  • qos policy-group modify

    Modify a policy group

    Availability: This command is available to cluster administrators at the admin privilege level.

    Description

    The qos policy-group modify command modifies a user-created policy group.

    Parameters

    -policy-group <text> - Policy Group Name

    Specifies the name of the policy group that you want to modify.

    [-max-throughput <qos_tput>] - Maximum Throughput

    Specifies the maximum throughput for the policy group. A maximum throughput limit specifies the throughput that the policy group must not exceed. It is specified in terms of IOPS or MB/s, or a combination of comma separated IOPS and MB/s. The range is one to infinity. A value of zero is accepted but is internally treated as infinity.

    The values entered here are case-insensitive, and the units are base ten. There should be no space between the number and the units. The default value for max-throughput is infinity, which can be specified by the special value "INF". Note there is no default unit - all numbers except zero require explicit specification of the units.

    Two reserved keywords, "none" and "INF", are available for the situation that requires removal of a value, and the situation that needs to specify the maximum available value.

    Examples of valid throughput specifications are: "100B/s", "10KB/s", "1gb/s", "500MB/s", "1tb/s", and "100iops".

    [-min-throughput <qos_tput>] - Minimum Throughput

    Specifies the minimum throughput for the policy group. A minimum throughput specifies the desired performance level for a policy group. It is specified in terms of IOPS or MB/s, or a combination of comma separated IOPS and MB/s.

    The values entered here are case-insensitive, and the units are base ten. There should be no space between the number and the units. The default value for min-throughput is "0". The default unit is IOPS.

    One reserved keyword, 'none' is available for the situation that requires removal of a value.

    Examples of valid throughput specifications are: "100B/s", "10KB/s", "1gb/s", "500MB/s", "1tb/s", "100iops", "100iops,400KB/s", and "800KB/s,100iops"

    Examples

    cluster1::> qos policy-group modify p1 -max-throughput 10IOPS

    Modifies the "p1" policy group and sets its max throughput value to 10 IOPS.
