Start iSCSI DHCP refresh

The start controller iscsiHostPort dhcpRefresh command initiates a refresh of the DHCP parameters for the iSCSI interface.

Supported Arrays

This command applies to any individual storage array, including the E2700, E5600, E2800, E5700, EF600 and EF300 arrays, as long as all SMcli packages are installed.

Roles

To execute this command on an E2800, E5700, EF600, or EF300 storage array, you must have the Storage Admin role.

Context

If the configuration method for the interface is not set to DHCP, the procedure returns an error.

Syntax

start controller [(a|b)] iscsiHostPort [portLabel] dhcpRefresh

Parameter

Parameter Description
controller The identifier letter of the controller that has the iSCSI host ports. Valid controller identifier values are a or b where a is the controller in slot A, and b is the controller in slot B.
iscsiHostPort

The host port label or the number of the iSCSI host port for which you want to refresh the DHCP parameters.

See the following for more information:

"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\"]
Note: For backward compatibility, the iscsiPortNumber, enclosed by braces [ ] rather than quotes and braces [" "] can still be used for E2700, E5600, or EF560 controllers (and other previous generations of E-Series or EF-Series controllers). For those controllers, valid values for iscsiPortNumber are as follows:
  • For controllers with integrated host ports, the numbering is 3, 4, 5, or 6.
  • For controllers with host ports on a host interface card only, the numbering is 1, 2, 3, or 4.

An example of the prior syntax is as follows:

iscsiHostPort[3]

Notes

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