Upgrade or Downgrade Scenario
When you are upgrading from a release earlier than Cisco SAN-OS Release 3.1(2), all modules operate
with bandwidth fairness disabled until the next module reload. After the upgrade, any new module that
is inserted has bandwidth fairness enabled.
When you are downgrading to a release earlier than Cisco SAN-OS Release 3.1(2), all modules keep
operating in the same bandwidth fairness configuration prior to the downgrade. After the downgrade,
any new module that is inserted has bandwidth fairness disabled.
Taking Interfaces Out of Service
You can take interfaces out of service on Generation 2 and Generation 3 switching modules. When an
interface is out of service, all the shared resources for the interface are released as well as the
configuration associated with those resources.
Note The interface must be disabled before it can be taken out of service.
Caution Taking interfaces out of service releases all the shared resources to ensure that they are available to other
interfaces. This causes the configuration in the shared resources to revert to default when the interface
is brought back into service. Also, an interface cannot come back into service unless the default shared
resources for the port are available. The operation to free up shared resources from another port is
disruptive.
Note The interface cannot be a member of a PortChannel.
To take an interface out of service using Fabric Manager, follow these steps:
Step 1 Select a switch from the Fabric pane, or select a group of switches (SAN, fabric, VSAN) from the
Logical Domains pane.
Step 2 Expand Switches, expand Interfaces and select FC Physical in the Physical Attributes pane.
You se e t he FC Physical > General tab in the Information pane.
Step 3 Scroll down until you see the row containing the switch and port you want to configure.
Step 4 Scroll right (if necessary) until you see the Status Service column.
Step 5 Select in or out from the Status Service column.
Step 6 Click the Apply Changes icon.
