Options

<rack-name>

Specifies the virtual HDFS rack to be modified. Each rack name begins with a forward slash—for example /example-name.

--add-client-ip-ranges <low-ip-address>-<high-ip-address>...

Adds a specified IP address range of external Hadoop compute clients to the virtual rack.

--add-ip-pools <subnet>:<pool>...

Adds a specified pool of OneFS cluster IP addresses to the virtual rack.

--clear-client-ip-ranges

Removes all IP address ranges of external Hadoop compute clients from the virtual rack.

--clear-ip-pools

Removes all pools of OneFS cluster IP addresses from the virtual rack.

--client-ip-ranges <low-ip-address>-<high-ip-address>...

Specifies IP address ranges of external Hadoop compute clients assigned to the virtual rack. The value assigned through this option overwrites any existing IP address ranges. You can add a new range through the --add-client-ip-ranges option.

--ip-pools <subnet>:<pool>...

Assigns pools of OneFS node IP addresses to the virtual rack. The value assigned through this option overwrites any existing IP address pools. You can add a new pool through the --add-ip-pools option.

--name <rack-name>

Assigns a new name to the specified virtual rack. The rack name must begin with a forward slash—for example /example-name.

--remove-client-ip-ranges <low-ip-address>-<high-ip-address>...

Removes a specified IP address range of external Hadoop compute clients from the virtual rack. You can only remove an entire range; you cannot delete a subset of a range.

--remove-ip-pools <subnet>:<pool>...

Removes a specified pool of OneFS cluster IP addresses from the virtual rack.

--verbose | -v

Displays more detailed information.

--zone <string>

Specifies the access zone that contains the virtual rack you want to modify.
