Brocade Fabric OS Command Reference 31

mode

Specifies the manner in which the ALPA is obtained in the event that the ALPA value is

already taken by another host. Valid modes include the following:

-s

Specifies a stringent ALPA request mode. In stringent mode, the login is rejected if the

ALPA is not available.

-f

Specifies a flexible ALPA request mode. In flexible mode, the host login is accepted

either with the requested ALPA value or with a different ALPA value if the requested

ALPA is not available.

--printalpamap F_Port

Displays the database entry for the specified port. An F_Port must be specified. The output

displays the PWWN-to-host-ALPA mapping.

--deletepwwnfromdb PWWN

Removes the specified port WWN entry from the database after the host has logged out.

--clearalpamap F_Port

Clears the ALPA values for the specific F_Port. This command removes the

PWWN-to-ALPA-value mapping from the database.

--addwwnmapping N_Port "WWN [;WWN2;...]" | --all

Maps one or more device WWNs to a preferred N_Port. All traffic form the specified

devices is forced through the specified N_Port, regardless of which F_Port the device logs

into. In the event the designated N_Port should become unavailable, an alternate port can

serve as a preferred failover port. This command only affects devices that are connecting to

the fabric after successful execution of this command; it will not affect devices already

logged in. If a device is already connected to the switch when its mapping is created, that

mapping goes into effect the next time the device connects. The WWN list must be

enclosed in double quotation marks. WWNs must be separated by semicolons.

The --all option indicates all device WWNs already mapped, for example, if you wish to

change an existing WWN mapping. It does not affect device WWNs that are not part of an

existing mapping.

--delwwnmapping N_Port "WWN [;WWN2;...]" | --all

Removes the mapping of one or more device WWNs to a preferred N_Port. The --all

option removes the mapping for all device WWNs currently mapped to the specified

N_Port. The WWN list must be enclosed in double quotation marks. WWNs must be

separated by semicolons. The mappings are removed upon execution of this command.

--addwwnpgmapping PG "WWN [;WWN2;...]" | --all

Maps one or more device WWNs to any of the N_Ports included in the specified port group

. The port group is identified by its port group ID. The --all option maps all currently

mapped device WWNs to the specified port group. The WWN list must be enclosed in

double quotation marks. WWNs must be separated by semicolons. The device WWN to

port group mapping takes effect the next time the device logs in.
