28 Fabric OS Command Reference

53-1003108-01

--pgdel pgid "N_Port1 [; N_Port2;...]"

Deletes one or more N_Ports from the specified port group. Deleted ports are

added to the default port group "pg0". The port list must be enclosed in quotation

marks. Ports must be separated by semicolons.

--pgrename pgid newname

Replaces the name of an existing port group with the specified new name. The

port group ID must not exceed 64 characters.

--pgremove pgid

Deletes the specified port group. The N_Ports in the port group that was deleted

are moved to the default port group, which is pgid 0.

--pgmapadd pgid "F_Port1[;F_Port2;...]"

Maps the specified F_Ports to the PG identified by the pgid. Upon execution, the

system identifies the least loaded N_Port in the port group and maps the F_Ports

to that N_Port. The port list must be enclosed in double quotation marks. Ports

must be separated by semicolons. Login balancing (LB) mode must be enabled

on the port group for this command to succeed. Use ag --pgsetmodes to enable

LB mode.

--pgmapdel pgid "F_Port1[;F_Port2;...]"

Removes one or more F_Ports that are part of the port group identified by the pgid

from their mapping to a corresponding N_Port. The port list must be enclosed in

double quotation marks. Ports must be separated by semicolons. Login balancing

(LB) mode must be enabled on the port group for this command to succeed. Use

ag --pgsetmodes to enable LB mode.

--pgsetmodes pgid "lb;mfnm"

Sets the APC modes for the specified port group. The mode list must be enclosed

in double quotation marks and the modes must be separated by a semicolon.

Alternately you can set the modes at the time when you create the port group with

the pgcreate command. The following modes are supported:

Specifies the login balancing mode for the specified port group. If login balancing

mode is enabled and an F_Port goes offline, logins in the port group are

redistributed among the remaining F_Ports. Similarly, if an N_Port comes online,

port logins in the PG are redistributed to maintain a balanced N_Port to F_Port

ratio. This operation is disruptive. Login balancing mode is disabled by default in

all port groups.

mfnm

Enables the managed fabric name monitoring mode (MFNM) in the specified port

group. This command changes the fabric name monitoring mode from "default" to

"managed". In both default and managed mode, the system queries the fabric

name once every 120 seconds, and if it detects an inconsistency, for example, if

the port group is connected to multiple fabrics, it triggers a RASLOG message.

The difference between default and managed fabric name monitoring is that in

managed mode, failover is disabled for all ports in the port group if the system

detects an inconsistency in fabric names.

You can add or remove MFNM from a port group, however, doing so will enable or

disable MFNM on the entire switch. RASLOG messages are generated only if

MFNM is enabled on the entire switch and multiple fabrics are connected to the

switch.

--pgdelmodes pgid "lb;mfnm"

Disables the specified modes on a given port group. The mode list must be

enclosed in double quotation marks and the modes must be separated by a

semicolon. For a description of supported modes, refer to --pgsetmodes.
