Disabling a network interface
You can disable the network interfaces on the storage system.
• You can only disable top-level interfaces. This includes bonded interfaces and NICs that are
not part of bonded interfaces.
• To ensure that you always have access to the storage system, do not disable the last interface.
If you want to disable the last interface, first enable another interface.
CAUTION: If you disable an interface, be sure you enable another interface first. That way you
always have access to the storage system. If you disable all the interfaces, you must reconfigure
at least one interface using the Configuration Interface to access the storage system. See
“Configuring a network connection” (page 236).
To disable a network interface
1. Log in to the storage system, and open the tree.
2. Select the TCP/IP Network category.
3. Select from the list on the TCP/IP tab window the interface to disable.
4. Click TCP/IP Tasks, and select Edit.
5. Click Disable Interface.
6. Click OK.
A confirmation message opens. If you are disabling the only interface, the message warns
that the storage system may be inaccessible if you continue.
7. Click OK.
If the storage system for which you are disabling the interface is a manager in a management
group, a window opens which displays all the IP addresses of the managers in the management
group and a reminder to reconfigure the application servers that are affected by the update.
