Disabling And Enabling Ports; Making Basic Connections; Connecting To Devices - HP A7533A - Brocade 4Gb SAN Switch Base Administrator's Manual

Disabling and enabling ports

By default, all licensed ports are enabled. You can disable and reenable them as necessary. Ports that you
activate with Ports on Demand must be enabled explicitly, as described in
WARNING! The fabric will be reconfigured if the port you are enabling or disabling is connected to
another switch.
The switch whose port has been disabled will be segmented from the fabric and all traffic flowing between
it and the fabric will be lost.
To disable a port:
1. Connect to the switch and log in using an account assigned to the admin role.
2. Issue the following command:
switch:admin> portdisable portnumber
where portnumber is the port number of the port you want to disable.
For 4/256 SAN Director and DC SAN Backbone Director (short name, DC Director): Issue the following
command:
switch:admin> portdisable slotnumber/portnumber
where slotnumber and portnumber are the slot and port numbers of the port you want to disable.
To enable a port:
1. Connect to the switch and log in using an admin account.
2. Issue the following command:
switch:admin> portenable portnumber
where portnumber is the port number of the port you want to enable.
For 4/256 SAN Director and DC Director: Issue the following command:
switch:admin> portenable slotnumber/portnumber
where slotnumber and portnumber are the slot and port numbers of the port you want to enable.
(Slots are numbered 1 through 4 and 7 through 10, counting from left to right.)
If the port is connected to another switch, the fabric may be reconfigured. If the port is connected to one or
more devices, these devices become available to the fabric.
If you change port configurations during a switch failover, the ports may become disabled. To bring the
ports online, re-issue the portEnable command after the failover is complete.

Making basic connections

You can make basic connections to devices and to other switches.
Before connecting a switch to a fabric that contains switches running different firmware versions, you must
first set the same PID format on all switches. The presence of different PID formats in a fabric causes fabric
segmentation.
For information on PID formats and related procedures, see
•
• For information on configuring the routing of connections, see
3. For information on configuring extended interswitch connections, see
on page 359.

Connecting to devices

To minimize port logins, power off all devices before connecting them to the switch. For devices that cannot
be powered off, first use the portDisable command to disable the port on the switch, and then connect
