Persistent ALPA policy

To ensure consistency among the different devices, after Persistent ALPA is enabled, all the

ALPAs become persistent, whether or not they were logged in before the Persistent ALPA policy

was enabled.

Disabling the Persistent ALPA policy

When you disable this policy, do not specify the value type (for example, flexible ALPA or stringent

ALPA). Use the following steps.

1. Connect to the switch and log in using an account assigned to the admin role.

2. Enter the ag

--persistentalpadisable command.

switch:admin> ag --persistentalpaenable 0

Persistent ALPA device data

Access Gateway uses a table to maintain a list of available and used ALPAs. When the number of

entries in this table is exhausted, the host receives an error message. You can remove some of the

entries to make space using the instructions in “Removing device data from the database”.

Removing device data from the database

Use the following steps to remove device data from the database.

1. Connect to the switch and log in using an account assigned to the admin role.

2. Enter the ag

--deletepwwnfromdb command.

switch:admin> ag --deletepwwnfromdb PWWN

In the example, PWWN is the port that you want to remove from the database.

Displaying device data

You can view the ALPA of the host related to any ports you delete from the database.

1. Connect to the switch and log in using an account assigned to the admin role.

2. Enter the ag

--printalpamap command with the appropriate option to display a database entry

for a specific F_Port. The following example will display an entry for F_Port 2.

switch:admin> ag --printalpamap 2

Clearing ALPA values

You can clear the ALPA values for a specific port.

1. Connect to the switch and log in using an account assigned to the admin role.

2. Enter the ag

--clearalpamap command with the appropriate option to remove the

PWW-to-ALPA mapping for a specific port. In the following example, the mapping for port 2 is

cleared from the database.

switch:admin> ag --clearalpamap 2
