PORT_1_PREFERRED_ID=(n1,n2,n3...)
NOPORT_1_PREFERRED_ID
PORT_2_PREFERRED_ID=(n1,n2,n3...)
NOPORT_2_PREFERRED_ID
May be set only when dual-redundant configurations are operating in a transparent
failover configuration. It specifies which targets and units are handled by the specified
controller port. First, specify, the total set of ID numbers with the preferred ID
number switch. If you enter two or more PORT_1_PREFERRED_ID (or PORT_2)
numbers, the numbers must be enclosed within parentheses and separated with
commas. When changed, the new setting for this switch takes effect immediately.
NOTE: Only target ID numbers set with the PORT_1_ID (or PORT_2) switch can be
preferred with the PORT_1_PREFERRED_ID (or PORT_2) switch.
The other controller is automatically updated to support the remaining ID numbers, if
any. For example, if a dual-redundant pair of controllers is set to ID numbers 0, 1, and
2, one controller can be set to respond to ID numbers 0 and 1; the other controller
automatically responds to ID number 2. The first controller presents unit numbers 0
through 7 and 100 through 107. The other controller presents unit numbers 200
through 207 to the controllers.
Specify NOPORT_1_PREFERRED_ID (or NOPORT_2) for one controller so it is
immediately available if the other controller fails. The other controller processes all of
the data during normal operation. However, if the other controller fails, the controller
assigned the NOPORT_1_PREFFERED_ID (or NOPORT_2) switch assumes control
of the targets assigned to the failed controller.
PROMPT=“new prompt”
Specifies a 1- to 16-character prompt displayed when the controller’s CLI prompts for
input. Only printable ASCII characters and spaces are valid. The new prompt name
must be enclosed within quotes. When changed, the new text entered for this switch
takes effect immediately.
