Parameter​

ParameterDescription

Identifying an iSCSI host port label

Identifying an iSCSI host port label​

You must specify a label for the host port. Follow these steps to specify the host port label:

  1. If you do not know the port label for the iSCSI host port, run the

    show controller command.

  2. In the Host interface section of the results, locate the host port you want to select.

    Note
    The port label is the complete value returned for the Port field.

  3. Enclose the entire value of the port label in both quotes and square brackets: ["

    portLabel "]. For example, if the port label is Ch 2 , specify the iSCSI host port as follows:

                            iscsiHostPort[\"ch 2\"]
    Note
    If you are using a Windows command line and the label contains a pipe (|), the character should be escaped (using ^); otherwise, it will be interpreted as a command. For example, if the port label is e0b|0b , specify the iSCSI host port as follows: 

                            iscsiHostPort[\"e0b^|0b\"]

Notes​

This operation ends the iSCSI connections for the portal and temporarily brings down the portal.
