All Fibre Channel ports on the switch are taken offline. If the switch was part of a fabric, the fabric
reconfigures.
To enable a switch:
1. Connect to the switch and log in as admin.
2. Issue the switchenable command at the command line.
All Fibre Channel ports that passed the POST test are enabled. If the switch has interswitch links to a
fabric, it joins the fabric.
Disabling and enabling a port
All licensed ports are enabled by default. You can disable and reenable them as necessary. Ports that
you activate with Ports on Demand must be enabled explicitly, as described in ”Activating Ports on
Demand” on page 30.
To disable a port:
1. Connect to the switch and log in as admin.
2. For the SAN Switch 2/8V, SAN Switch 2/16V, SAN Switch 2/32, and SAN Switch 4/32, issue the
following command:
portdisable portnumber
where portnumber is the port number of the port you want to disable.
For the Core Switch 2/64 and the SAN Director 2/128, issue the following command:
portdisable slotnumber/portnumber
where slotnumber and portnumber are the slot and port numbers of the port you want
to disable.
If the port is connected to another switch, the fabric might reconfigure.
To enable a port:
1. Connect to the switch and log in as admin.
2. For the SAN Switch 2/8V, SAN Switch 2/16V, SAN Switch 2/32, and SAN Switch 4/32, issue the
following command:
portenable portnumber
The portnumber is the port number of the port you want to enable.
For the Core Switch 2/64 and the SAN Director 2/128, issue the following command:
portenable slotnumber/portnumber
The 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 might reconfigure. 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 might become disabled. Reissue the
portenable command after the failover is complete to bring the ports online.
